Firefox Aurora 13 is out – SPDY on by default and a list of other improvements

We have just released Aurora 13, together with a number of improvements.

Highlights

There are a couple of things we’d like to shine some extra light on here:

SPDY on by default

The SPDY control brings responsive and scalable transport to Firefox. It allows for multiplexing and connection sharing and is SSL only. It will offer faster page loads and better scalability for SPDY-enabled web servers.

Our first implementation was in Firefox 11, but now with Firefox Aurora 13 it is on by default!

User Agent change for Mobile

The preferred way for web sites to offer content depending on the device is to use CSS Media Queries. However, there is a good amount of user agent sniffing still going on out there, so we wanted to make you aware of the change/difference between Firefox on mobile phones and on tablets, as outlined in Mobile and Tablet indicators.

For Firefox on mobile it will be:

Mozilla/5.0 (Android; Mobile; rv:13.0) Gecko/13.0 Firefox/13.0

Firefox on tablets will be:

Mozilla/5.0 (Android; Tablet; rv:13.0) Gecko/13.0 Firefox/13.0

List of improvements

Here are all the improvements we’ve made complete with links to each bug listing for those who want to read up more on respective implementation.

    It seems to me that firefox is becoming more a software to develop webpages and less a browser…

      Is there any specific you are referring to? Basically, all features listed here are there to make web browsing faster and better, and to offer web developers to build richer web sites.

      If that’s what you think then you need to think the same about IE10, Chrome, Safari, and Opera. They all have had built-in tools like this for a LONG time while Firefox had to rely on the Firebug addon.

        Yes, all web browsers have developer tools, which I believe is great. Firebug set the standard and definitely also raised the bar for how debugging in the web browser could be done.

    really loved to see SPDY on by default…
    are there any chances of making SPDY, a web standard.
    and UA changes…
    media queries dont work properly on all devices, so this was necessary.

      Yes, it’s a nice step forward.
      The group developing SPDY are working towards a standardization.

      We’re working on UA changes, and the most notable ones in Aurora 13 are the new tab page with the most visited pages for the current user and that the Awesome Bar now auto-completes typed URLs

    Yes we value the fast,I am becoming to feel the ffx is more comfort in developing as long as end user development.

    Watching you in Aurora 12.0a2

    why to delete -moz prefix ?
    now I need to find a solution in all conditions of my scripts to check
    if it’s mozilla under version 13 to allow -moz filters…
    great progress guy, continue like this and maybe in 20 years we will stay
    cool to pass time with my family rather than corrrect and correct css and js

    ok guys, I understand that you have your reasons to clean
    your code, but what’s the sens to remove -moz prefix only on border-radius and border-shadow but not -moz-linear-gradient ?

    come on, just REMOVE those idiotic profiles so we can finally implement firefox to enterprise environment. MS App-V etc. just hates your profiles.. they just doesn’t work.
