Download Mozilla Firefox 4 RC 2

Mozilla has finally released a Release Candidate version of Firefox 4. Hopefully we will soon have the final version of Firefox 4 unless there is no more Release Candidate (RC 2) version before the final release. Firefox 4 RC 2 is considered to be stable and safe to use for daily web browsing, though the features and content may change before the final product release. At this time many Add-ons may not yet have been tested by their authors to ensure that they are compatible with this release. If you wish to help test Add-on compatibility, please install the Add-on Compatibility Reporter – your favorite Add-on author will appreciate it!
