Mozilla has pushed out version 11 of its Firefox browser complete with the usual security patches, as well as a few new features, such as add-on sync and two new developer tools. The company was able to meet its six-week release schedule, even though earlier in the week it had announced that Firefox 11 would be delayed due to two vulnerabilities discovered at the Pwn2Own competition.

Apparently, the vulnerability in question was one that Mozilla had already identified and fixed on its own, so they decided to go ahead with the release. However, to avoid conflicts with Microsoft's Patch Tuesday, Firefox 11 will initially be pushed out through manual updates only and not via the automatic update mechanism.

The most notable new feature for end users is the ability to sync add-ons across multiple computers, something that's been available to Google Chrome users since late 2010. To enable the new feature, Firefox 11 users will simply need to have signed up for the free Sync service, which also synchronizes your bookmarks, passwords, settings, history, add-ons, and tabs with Firefox on other computers.

3D Page Inspector View (Tilt)

For developers, Mozilla has included a new style editor and WebGL visualisation tool. The first lets developers edit CSS documents on-the-fly and immediately see the effect it has on the design of the page without leaving the browser. Meanwhile, Page Inspector 3D View (nicknamed 'Tilt'), is a WebGL-powered "view source" option on steroids, which highlights what raw code looks like when the public sees it on a live Web site.
