Firefox 2.0 is right on track to finalization as the Release Candidate 1 version has been made available for download via mozilla.org. Close to fifty editions of the Firefox 2.0 RC1 can be downloaded, covering just as many different languages. Additionally, all the variants of the Mozilla browser deliver support for Windows, Mac OS X and Linux i686. Mozilla's Tim Riley has announced the release on September 27, 2006: "This is just to let everyone know that the QA testing for RC1 is complete. The set of locales that are ready can be found in the shipped-locales file in bug 353341. 49 locales are being released."

Riley even provided a summary of the areas QA tested: smoketests and BFTs, JS tests, Security Regression test suite, L10n trademark and functionality, extended Extension testing, extended top 100 sites testing and software update testing.

"We have a handful of bugs that look reasonable to cause a FF2 RC2," stated Mike Schroepfer, Mozilla's director of engineering. "We are in the end game here - which means days matter and our tolerance for risk is *zero*. We will not take bugs unless they are of great benefit: crashes, web compatibility, and major regressions. IMHO [In My Humble Opinion] FF2 RC1 is already a tremendously superior product to FF15. So let's wrap this up!"
