Slechts een week na het verschijnen van RC2 is Firefox 3 RC3 vrijgegeven. Het wordt iedereen die reeds gebruik maakt van deze browserversie aangeraden te upgraden naar de nieuwste versie.

Released: June 11, 2008

This third Firefox 3 Release Candidate is a preview release of Mozilla's next generation Firefox browser and is being made available for testing purposes only.

Preview releases are published to collect feedback from Web developers and our testing community before advancing to the next stage in the release process. The final version of Firefox 3 will be released when we qualify the product as fully ready for our users. Users of the latest released version of Firefox should not expect all of their add-ons to work properly with this preview release.

Please see below for an extensive list of features and enhancements found in Firefox 3, as well as known issues and frequently asked questions. As always, we appreciate your feedback either through this feedback form or by filing a bug in Bugzilla.
