Firefox 6.0 Released

The Mozilla organization today released a new version, 6.0, of its Firefox Web browser, for Mac OS X, Linux, and Windows.  Version 6.0 incorporates some new features, some of particular interest to Web developers, including:

  • Added support for the latest draft version of WebSockets with a prefixed API
  • Added support for EventSource / server-sent events
  • The address bar now highlights the domain of the website you’re visiting
  • Added Scratchpad, an interactive JavaScript prototyping environment

More changes and links to further information can be found in the Release Notes.  The new release also incorporates several stability and security fixes.

You can obtain the new version, in 70+ languages, from the download page.  Alternatively, you can use the built-in update mechanism (Help -> About Firefox -> Check for Updates).  Because of its security content, I recommend that you upgrade to the new version reasonably quickly.

If for some reasons you are still using Firefox 3.6.x, Mozilla has released version 3.6.20, incorporating security fixes; you can download it here.  The 3.6.x series will only be supported for a limited time, so I encourage you to migrate the current version as soon as you can.

Update Tuesday, 16 August, 19:20 EDT

For those using the 3.6.x browser version, Mozilla has published a Security Advisory [MFSA 2011-30], detailing the security vulnerabilities fixed in 3.6.20, several of which are rated Critical.  If you must stay with 3.6.x, the upgrade to 3.6.20 is strongly recommended.

Update Tuesday, 16 August, 20:37 EDT

The Mozilla Foundation  Security Advisory [MFSA 2011-29] is now available, and lists the security fixes, many Critical, in Firefox 6.0.  I suggest you upgrade your installation as soon as you conveniently can.
