35 days logo

Over the next 35 days we’ll be talking about all of the new developer features in Firefox 3.5.

The upcoming release of Firefox 3.5 is a big upgrade for users.  It includes new privacy features, improvements in interactive performance and a new JavaScript engine that will improve the experience for users using script-heavy web sites.  These are all features that users will appreciate and talk about.

But what Firefox 3.5 really represents is a huge upgrade to the web itself.  We’ve included support for audio, video, threads in JavaScript, new canvas features, tons of new CSS features, downloadable fonts and geolocation.  While Firefox 3 was a signifigant upgrade for the web’s users, Firefox 3.5 does the same for developers.

Because of the sheer volume of new features for developers in Firefox 3.5 we’ll be spending the next 35 days featuring all of them, with two posts a day, every day.  Each day’s first post will describe one new feature in Firefox in depth – how to use it, why it’s there and some examples of what it can do for you.  The second post will be all fun – examples of demos that people have put together using all of the features that are in Firefox 3.5.

Like much of what we do at Mozilla this is a community-led project. We’ve reached out to members of the Mozilla and web developer community for posts and demos.  Some posts will be written by core Mozilla hackers, but many of them will be written by people who are just excited about the chance to use this technology in the wild.

My personal belief is that these posts represent Mozilla’s dreams for the future of the web.  We are not a company like every other browser vendor – our core mission is to improve and protect the web.  Firefox 3.5 represents what we think the next stage of the web will be – interactive applications, video, web sites collaborating and sharing information – all via the browser.  Our hope is that each of you will take what we post here, encourage other browser vendors to implement similar features where they haven’t already, and do your part to keep the web vibrant.

    @ CG: You’ve got it @$$-backwards… Mozilla builds the browser; the independent developers rework the add-ons to work within the new browser version.
    @Alan & Lycanthrope: I totally agree with both of you. Less fluff/bloat, lightning-fast, add-ons only if you want ‘em. Look at how popular salad bars have become. Why? They let YOU personalize the salad to your tastes. Who could ever contest that?! FF rocks, and I’m a REALLY impatient b!t©h, so give us 3.5 now, Mozilla, or I’m calling my Daddy! ;)

    I am using firefox 3.5b4 and I can say it’s simply awesome, but seriously more 35 days of waiting is not cool. why don’t you people try to speed up the release(just kidding). You guys have done a great job and I am proud to be a part of it.

    Guys, first off the features in 3.5 are NOT bloat.

    Geolocation lets web sites know your physical location (if you choose, off by default) (think google maps)

    Audio/video elements are for sites to embed video and audio WITHOUT the use of flash… and you can manipulate these video’s with JS. So this means videos can have an effect on the page… the page to the video… trigger events… the sky is the limit.

    TraceMonkey is the new javascript engine… The latest nightly is now faster at Sunspider benches than chrome 1(whoa!) (1423ms vs 1556ms)

    Private Browsing is just that.

    However, Mozilla outlined that the next version (3.6 ATM, and not that i can’t wait for 3.5!!) is really the dream come true… they’re going to implement lightweight themes and add-ons, and increase start-up time, UI interactions, etc. noticeably. The same improvements that doubled Firefox 3.5 browser’s java script performance is going to be used internally for the UI.

    Firefox 3.5 most certainly rocks as loading facebook and other JS intense sites is a quick, short and painless… I’d go as far to say it takes a 3rd the time on average, and i can’t wait to see sites that start using the video/audio elements. Like the article states, this is a treat to the developers, we’ll get more presents from mozilla with the next version :p

    I am a longtime fan of Firefox. I have used it and loved it since it was Phoenix 0.3.

    So far I’m not impressed with FF 3.5. I have tried beta 4 and beta 99. There are many sites and pages that just won’t load.

    I too am an ardent fan for Firefox and have been looking forward to upgrading to 3.5. Now that has happened I am extremely disappointed to find that it takes upwards of 8 minutes to start. This is totally unacceptable and will have to switch to IE until the problem is fixed.
