Firefox 3.6 feedback

Firefox 3.6 was released on Jan 21st and has already been downloaded more than 35 million times! It features a faster JavaScript engine, faster DOM performance and a bunch of new HTML5 features. Highlights for web developers include support for the WOFF font format, new CSS features like gradients and multiple backgrounds, drag and drop, File API, device orientation, and more. Want to see the full list? Look at our Firefox 3.6 for Developers page on developer.mozilla.org.

We hope that you took the time to test Firefox 3.6 on your web sites before the release. If you didn’t, it’s not too late to let us know about issues. Here are a few problems that we’ve seen in the wild so far:

  • We’ve seen a couple of issues with the FCKEditor component, used widely on the web. It apparently doesn’t handle dates after 2009 properly (this is the first major browser release in 2010, a new decade!) and it also has some problems with document.readyState.
  • People who had the YSlow extension installed saw crashes with Firefox 3.6. YSlow has been updated to version 2.0.6 to fix the issue
  • Some Facebook apps were broken by a change we made to comply with the upcoming HTML5 standard. We updated element.getElementsByTagNameNS and document.getElementsByTagNameNS to no longer case-fold when doing tag name lookups. (We strongly suggest that you only use lower-case for tag names for many reasons, including this.) For more information, please see this note from Henri Sivonen about what’s changed. Facebook has since fixed the issue in their code, but other sites may also be tripping over this.

We’re looking for feedback on any developer-facing regressions you’ve seen in 3.6 from 3.5. Please comment on this post if you have feedback.

    Not so much of a functional regression.
    However, I am not too fond of the new tab behavior. Previously a new tab would open after all existing tabs. Now it opens next to the window in which it was opened. Can this be configured? Do you know the bug# that changed this behavior? Thanks.

    I know of at least two issues.

    1. On this site:

    http://areyouwatchingthis.com/login

    The Login text appears twice. It only appeared once on Firefox 3.5. Still investigating why.

    2. Flash is horribly broken when displayed in the sidebar. This is a major regression.

    I am getting the following error repeatedly when typing in a regular input field, afaik it’s triggered on keyup/keypress.

    [Exception… “Component returned failure code: 0x8000ffff (NS_ERROR_UNEXPECTED) [nsIPrefBranch.getBoolPref]” nsresult: “0x8000ffff (NS_ERROR_UNEXPECTED)” location: “JS frame :: file:///C:/Program%20Files/Mozilla%20Firefox/components/nsFormAutoComplete.js :: anonymous :: line 97” data: no] file:///C:/Program%20Files/Mozilla%20Firefox/components/nsFormAutoComplete.js Line 97

    When I set the autocomplete attribute it’s gone, so I presume it has something to do with a security setting or maybe an add-on?

    Cheers,
    Boye

    Note that there are other case issues related to the getElementsByTagNameNS one in 3.6 – for instance, after adoptNoding an XHTML element with (partially) uppercase attributes into an HTML document, the attributes are no longer available using getAttribute (although they can be accessed using getAttributeNS and the attributes collection). ChatZilla got bitten by this ( https://bugzilla.mozilla.org/show_bug.cgi?id=541647 ).

  5. Jesper Kristensen

    bug 476856 changed handling of syntax errors in CSS urls, which broke the following site, which works in IE8, Chrome and Firefox 3.5: https://www.tinglysning.dk/

    They have “background-image: url(foo.gif’);” in their style sheet, which breaks the entire rest of the style sheet in Firefox 3.5, but only breaks the next single block in all other browsers.

    There is black rectangle flicker while loading java applet. In FF 3.5 it’s ok.

    I use an animated Java Applet weather map everyday and I have seen no black rectangle during or after loading. This is a Weather.com Applet that is about 14 years old.

    I’m using version 6 Update 17 java Runtime on Windows Vista Home SP2.

    Your second comment about problems with FCKeditor is really a problem with another editor named KTML, seems to be an old extension for Dreamweaver.

    With Firefox 3.6 is changed way that new tab opens. In Firefox before 3.6 new tabs were opened in the end of tab toolbar (which was perfect for me.) In Firefox 3.6 new tab opens in the tab next to active one. Please, at least put the option in “tab” submenu to choose the way for opening tabs.

    I work on a site where I have input fields with 25px height (21px height+ 4px padding top). The problem occurs on FireFox 3.6 where the text is automatically vertically centered so the CSS should look like 25px height without any padding top. What I should do in this case?

    I tested on Windows and MAC with FireFox 3.5.7 and FireFox 3.6

    I don’t know what problem i am getting in my FF 3.6 version but when i opened some of live stock quote website. mozila getting crashed and suddenly it’s closed without any warning or notice before close. these happened to me many times after upgrading from 3.0 version

    February 9th, 2010 at 12:17

    1. darkyndy

      This happened to me too, but I think that the main problem is the operating system (Windows 7 in my case). On Windows Vista I didn’t had any problems … but with Windows 7 there are some…

      About my problem posted above, the solution was to use for input fields only padding and no height. In this was the text is center aligned and works in all browsers.

    I am not a developer.

    I have found two problems that I could only alleviate by going back to 3.5.7

    1. In using the Google Docs spreadsheets, my comment notifications (the orange upper right hand corner in a cell) no longer display, although the comments are still there.

    2. In using the ebill billpay software through my brokerage (Fidelity) I no longer see any icons, just a recessed, grey lined white space where icons used to be. Some example icons were for a calendar to drop down and set a date or a little ebill icon that one could click on to go to the billers site and see the bill. The functionality was gone too.

    Sincerely,

    Tom

    Is it me? Or has any one else noticed that Mozilla, gmail included, freezes alot since the last download. Almost daily now I can count on loosing content because Moziila freezes. I hope this changes soon.

    February 16th, 2010 at 00:02

    1. Transcontinental

      AJM, I have had as far as I’m concerned not one single freeze nor crash, not one single problem with Firefox 3.6 running on XP SP3 Home (with 80 extensions moreover), and I’ve been running FF 3.6 ever since the moment it was made available. I may add that comments on forums (and I read quite a few) are not particularly talkative regarding what could look like Firefox 3.6 chronic problems; on the contrary :) The “Thing” here is running fast ‘n smooth!

  17. Michael

    Not a development issue, but a minor niggling user interface one:

    Why was it necessary to change the default tab-opening behavior to copycat IE? Why was it necessary to not even put the option to revert this behavior under Tools > Options > Tabs?

    Yes, I know, you can go into about:config to change it back to what we’re used to, but that seems gratuitously unnecessary. If I wanted a browser that “looks and feels” like IE in everything down to tab-opening behavior, I’d use frickin’ IE. If you want to give users the *option* for IE tab-opening-next-to-your-tab behavior, great. But forcing all of us who are actually used to the up-til-now-existing Firefox tab behavior to face a random annoying user interface change like this at the update and either adapt or dig through about:config, is poor design.

  19. Transcontinental

    Quite true, Michael, I agree. I remember having read somewhere (a source of authority as to what I recall) stating that the new tab-opening behavior was “smarter” (that was the idea) on the long term… I disagree on that, I think preference for a tab-closing behavior is strictly related to one’s preference of organization, like FIFO or FILO…
    Whatever, the choice should be clearly implemented in the Options window.

  20. David Kloepper

    IE Tab is broken under the new version. Coral IE Tab is not an acceptable substitute and IE Tab is no longer supported by the old developer. Millions of Firefox users are affected by this problem. IE Tab is critical to my usage of Firefox, so I will have to abandon all future Firefox developments if this is not fixed.

    Firefox 3.6 doesn’t seem to be reading the stylesheet on a client’s site of mine:
    http://www.sacredspaceacupuncture.com

    No other sites of mine seem to be affected like this…. and all other browsers are fine, including Firefox 3.5.. well it was until i updated

    (i haven’t debugged in IE for style issues so ignore that for now)

    hmmm…

  22. Rudi Olckers

    I’m experiencing the same issue as darkyndy. I require an input text field of height e.g. 50px. FF3.6 vertically aligns the input text field value in the middle. This is not happening in FF3.5.8/7, IE7 nor Chrome (where the value is top-aligned). I can do a work around but I have a suspicion that I’m not the only only experiencing this issue as many users have not upgraded to FF3.6 yet. This is a sample of how to reproduce the issue:

    .classA {
    height: 50px;
    background-color: red;
    }

  23. Bambu

    Add me to the list of those who aren’t happy about the new tab behaviour! I would like to see an option to go back to new tab being added to the end of the list of tabs.

    @Michael – what’s the about:config option to return to the old behaviour? I looked at it and didn’t see what could be changed.

    @David Kloepper – what don’t you like about Coral IE Tab? I think it works as well as, if not better than, IE Tab.

    February 23rd, 2010 at 11:23

    1. David Kloepper

      Check out the myriad of negative comments about Coral IE Tab on the add-ons website at https://addons.mozilla.org/en-US/firefox/addon/10909. Also check out the many distressed comments about the death of the original IE Tab and the inadequacy of Coral at https://addons.mozilla.org/en-US/firefox/reviews/display/1419?show=20&page=16. Coral simply does not (yet?) have the same functionality as the original despite the addition of AdBlock. Perhaps the new developer will fix this. Until then, I will be stuck in a time warp with other Firefox 3.5 users. Or maybe I’ll revert to Opera if security becomes a large issue with 3.5.

    Downloaded 3.6 a few days ago. I used to like this product but after using it for short periods of time it gets slower and slower until it just locks the whole system up. My broadband connection is operating at the same speed I used to get on dial up about 5 years ago. I hope you have some fixes coming. Also, trying to post comment on your feedback site was impossible. The send button never did activate. What is going on with what used to be a good browser?????

    Hi Chester,

    Unfortunately, all versions of Firefox 3.x have a bug in its
    AppleScript implementation.

    The result is that URL Manager Pro cannot query the current web page
    and the Add Bookmark command does not function.

    Thanks.

    Is there any way to inform Mozilla so they could fix their AppleScript implementation problem? It sure would be great to be able to use URL Manager Pro with Firefox 3.x! :D Let me know.

    February 27th, 2010 at 18:45

  28. Edward

    I hope the Mac OS Apple events can be made to work properly with the new Firefox soon..

    Currently there is a problem which does not let it properly integrate with URL manager pro, it is very inconvenient that it is not working.

    Thanks..

    It seems that Firefox 3.6 has a bug in its AppleScript implementation.

    Since Firefox 3.6, all of the flash based apps on facebook are not working. I checked the apps using Firefox 3.5.8, the apps run.

    is it firefox 3.6 that cause this problem? If not, then how come version 3.5.8 makes flash apps work?

    March 2nd, 2010 at 12:21

    I would like to see FIREFOX add a feature that would allow me to customize what the F1-F12 keys can do. I am especially interested in a very simple feature that would allow me to setup/assign my email address to an F-key. Many times I have to enter my email address and one slip of the finger can end up with an incorrect or misspelled address. I would live to be able to go under the TOOLS > OPTIONS > GENERAL > {new tab here} ENTER F-KEY ASSIGNMENT and have a spot to enter my email and assign or remap the F-KEY to this.

    How do I fix this broken behaviour?

    March 12th, 2010 at 03:19

  38. JT

    Ugh. The new tab behavior is awful. It’s to easy to lose track. FIFO just makes sense. The old way should be the default, and the new method should only be an option. Stop trying to copy the failures of IE.

    Hi!

    Mozilla keeps changing interfaces – This is a real pain as we have to keep producing yet another accompanying DLL for each release of firefox. This sort of movement of interfaces is one of the reasons that commercial companies and products shy away from Mozilla.

    For example, in 3.5, your interface IID for IDOMNSELEMENT is f0aef489-18c5-4de6-99d5-58b3758b098c , but then in 3.6 its changed to c9da11bc-32d4-425e-a91f-7e0939c39251 – How can we get around continually having to rebuild with newer items each time you re release your product? If you had a “real” com server instead of XPCOM, the interface IDs would just be in the registry and we could read them back without the continual need for our engineers to play catch up to support mozilla, each time you re release ! tsk.

    There is almost certainly a regression when using 3.6 to authenticate facebook apps created using the facebook flash/flex libraries. I only ever tested it on 3.6 but have since found at least one other person reporting a problem with 3.6, and many others reporting broken facebook apps starting Jan 2010: they do not specifically blame 3.6 but it’s a likely culprit considering neither api’s nor their code changed around the time 3.6 was introduced. I can confirm my app works on Safari 4, see blog post below for someone else (ny) reporting it working on 3.5.8 but not 3.6

    The behaviour on 3.6 is that, when attempting authentication, it does switch to the browser but never actually opens a tab with the relevant page.

    Just encountered a change in 3.6 when using the Web Developer Extension. Whereas in all other versions if you hit ‘images’ > ‘view image information’, a full detail of ALL images is provided, under 3.6 no background images are shown. I went back to 3.5.8 and it works fine and shows all images. Not sure if this is a bug in FF3.6, a setting I need to alter or the WD extension requiring an update?

    Not that I have a lot against yahoo, I just don’t want the tool bar appearing at random intervals on Firefox. If I want it I’ll install it, thank you. One thing that brought me to Mozilla was the high BS factor with IE. Now Moz seems to be copying ms shoveling BS updates full of unwanted mandatory updates pushed on me. Make all the changes you want but please let me decide if i want to use them. If I could I would go back about 8 years to those versions where simple clean workable was the rule. change for change sake isn’t necessarily useful!

    I’ve used Firefox for years but it has incompatibility issues with my computer since the newest updates. My computer refuses to wake up from sleep, I get slow downs in checking my email and crashes. When I remove it and use Windows my computer works fine. I’m sorry but Firefox will no longer be my browser of choice.

    I am having constant freezes in firefox 3.6.1 on windows 7 x64. Checking the task manager shows firefox is using 50% of my CPU (on a two-core machine, so it’s locking out one core)
    even typing this message is taking forever because every 38 characters the screen stops responding. Anybody got any tips? This is quite terrible.

    April 22nd, 2010 at 19:29

  49. Kevin

    I had problems with 3.6.x and had to revert back – now using 3.5.9 and everything is fine again including the tab behaviour.

    I won’t be updating again until this reverts back to how it was as I use this a lot – the change is a right pain when you’ve got tons of windows open like I have.

    I run XP Home and it never had a problem with Firefox until 3.6.x – the crashing and freezing makes it unusable.

    To revert back simply download an old version I suggest 3.5.9 and install. Then under Tools > Options > Advanced > Update uncheck the ‘Automatically download and install the update’ button and check ‘Ask me what I want to do’. This will ensure that the new version won’t re-install itself.

    @Ad Bouwen: I have the exact same issue in my work enviro, but instead of 3.6.3, I have 3.5.5 and it CONSTANTLY downgrades to 3.0.6. If I close out all instances of the browser and re-open it, it will upgrade to 3.5.5. Very bizarre…

    Mozilla Firefox version 3.6 was a forced update on my computer by Mozilla. I would have never allowed it because now my realplayer downloader doesnt even work at all, and when I researched the problem, found out realplayer doesnt support F.F. v3.6 BOGUS! Is there anyway to disable the upgrading of mozilla firefox from the version prior to this one if I uninstall, and reinstall? Why dont you program twits leave well enough alone

  56. Ms.Snow

    I would really like to see firefox give us a little more room in the plugin section. I really resent not being able to permanently remove a plugin. The enable/disable feature is stupid… If I dont want a plug in in there at all I have to put up with it being there in disabled mode. Plus the automatic detection of a bunch of plugin’s that I never wanted in the first place take over that section and I cant get rid of them. Please Please Please give us a feature that lets us remove what we dont want there.
    I also would like to customize how my tool bar fits together the size and places that each feature is shown.

      I like your comment very much, Ms Show. Your comment is what I really want to let Firefox know.
      Always give us choices, please.
      I have three browsers on my computers: IE, Firefox, and Chrome. However, I only use firefox because I have the freedom to choose. So don’t take away my freedom. It is the most important feature that keep me stay with Firefox.

    URL Manager Pro 3.5 b11 works for me in with Firefox 3.5.8 but not in Firefox 3.6

    So what gives here? They fixed it for 3.5.8 and broke it again in 3.6?

    Makes no sense to me.

    I am having horrible problems with FireFox 3.6.10. Especially typing lag, and freezing, and videos playing choppy. My computer is only 8 months old, I have super-high performance DSL and plenty of memory, etc.

    I can concur what Rex said. The longer it’s open, the worse it gets. I can’t even get the menus to drop down faster than like 15-20 seconds! It’s unbelievable.

    Has anyone found a solution? If not, I’m switching to Opera or Safari.

    I am running Windows 7 OS.

    Too many connectivity and usability problems with FF3.6.9 and FF3.6.10 to list here.

    The latest: FF simply refused to connect via port 80, even while Thunderbird and Chrome connected. Upon clicking on a bookmark, the url appeared in the tab (not the title), and either a “remote site reset” FF error page appeared, or FF just hung. Safe mode was OK but very slow.

    I uninstalled; downloaded and reinstalled FF3.6.10, and it still wouldn’t connect. I then downloaded FF3.5.13, installed it — and it runs fine.

    I want HTML5 and the new JavaScript engine, but application basics have to be bulletproof: Connectivity; basic functionality; add-on operation; basic malware protection. In my user’s opinion, FF3.6.9 and FF3.6.10 were not ready for release. I know that you guys know these things already, and I look forward to a really robust release in the near future.

    Firefox 3.6.11 is freezing with yahoo mail application. it is getting stuck with loading yui api’s or a geo package. Performance of this browser seems to be lower than the 3.6.3 on xp sp2 machine.

    Started building an upgrade to my website. It runs well on Safari, Chrome, IExplorer, FIreFox 3.5 but not when tested with Firefox 3.6 …my problem concerns where div and iframes are placed by the browser (v3.6) using CSS rules. Apparently, something very important broke in the new release.

    Is unpredictable result via CSS rules a wide spread problem using the latest release?

    Cheers, Jim

    P.S. The upgrade to my site has not been uploaded to the server. I would it to run version 3.6 first.

    I had to download the version for yahoo.ca & everything works proper & great till it up dates to the 3.6 thing then the yahoo email treats every email out going like spam so I turned the auto updates to ask & then ignore it or if I update it fails the emails again & again.So maybe you should try to figure out what you did wrong & go back to what works,Don’t believe me .go to yahoo answers & just read the hundreds of angry & upset folks concerns there.
    as a mechanic the experiance teaches “IF IT AIN’T BROKE, DON’T FIX IT”

    I am not a developer but have used FF since 2003. Since the update that changed the way that FF handles Adobe Flash crashes life has been difficult for anyone wanting to watch flash videos via FF. Previously Flash crashes happened maybe once a month, causing the browser to crash as well. Now I can experience 10 or more failures of Flash EVERY day. mI have read as many articles as possible and implimented all suggestions all to no avail. I have also tried FF 4 beta to no avail. Either get this sorted or lose a great many FF users to other platforms. I am now seriously looking at Opera and even IE because this issue is driving me round the twist – GET IT SORTED.

    As other users have found, watching video via firefox ultimately makes it crash. I’ve looked at the Task Manager while Firefox is running and it just consumes more and more operating memory. It does not purge as you watch, just keeps eating more. The last time it crashed it became impossible to reboot and worse yet I cannot even uninstall it !!! I am at a loss, I want if off my machine for now and cannot accomplish this. Anyone with a solution? It would be greatly appreciated.

    I guess i was lucky as mine did work but you guys got to say perfect the number instead of uping the number with some new tricks but not fixing the last problems & stop with the “BETA” crap.
    Its the best browser but you guys are as sick & twisted as microsoft as you think the numbers must be upped as the microsoft folks do.Mostly they do that because explorer is so full of holes & with a built in hole from day one they make their numbers go up because they can’t fix the last one but sell the puke & white wash to the general public to make them think they have made improvments where its just the same old dog ! Mocrosoft is in the busness of selling software so expect they will continue to up the number while the fools rush out for the new..Its seems firefox is trying to do the same but not so scitzophrenicly in detail as microsoft.
    Kind oof like the north american auto market with its built in flaws!

    Does anyone know how to export Bookmarks from Firefox 3.6.13 into Safari and/or Opera? Firefox is not letting me do this.

    I`ve just gone back to 3.6 having used 7 for a short time and 7 drives you nuts! In 7, after about 10 mins, you constantly have to move the mouse around to get a page to load no matter what tips you follow from Mozilla, it`s absolutely crazy. I wouldn`t go back to using 7 if they paid me. I only upgraded because 3.5 kept crashing on Windows 7

    I am having trouble reaching specific websites to pay bills. When I type in the address and press go Firefox 3.6 redirects me to all different sites. I cannot reach the address that I type in. I keep getting redirected to sites I do not want. This makes Firefox 3.6 worse than useless because I cannot do the simple basic step of entering a known address and going there.

      It sounds like your computer is infected with malware. See this support article for help. In general, the Firefox Support site is a better place to get support than commenting on a blog.
