A recently disclosed vulnerability in the Firefox 3.5 web browser forced the Mozilla Firefox development team to release version 3.5.1 of the web browser early to fix the vulnerability. The vulnerability, which is affecting all operating systems that Firefox can be installed on, is linked to the Firefox JavaScript Tracemonkey engine. A temporary fix was published soon after that would disable part of the Javascript engine.
The Mozilla Firefox team is currently distributing the Firefox 3.5.1 update to all mirror websites. It is expected to be announced publicly in the next 48 hours giving Firefox 3.5 users a change to update their web browser to fix the security vulnerability.
The release is not available on any of the popular download portals yet. We took the liberty to upload the US version of Firefox 3.5.1 for the Windows operating to a free file host from where it can be downloaded. Users who use a different operating system or language will have to wait a while longer before they can download and update their version of Firefox.
The big download portals are expected to offer Firefox 3.5.1 soon as a download on their website. Cautious users might want to wait until the new version has been announced officially by the Firefox team. Users who have applied the temporary workaround to Firefox 3.5 should undo the changes by doing the following:
Type in about:config in the Firefox address bar and hit enter. Now filter for the term javascript.options.jit.content and double-click it afterwards to set it to true which enables the Tracemonkey JavaScript engine.
Firefox 3.5.1 US for Windows can be downloaded from Mediafire.

It breaks Google Gears compatibility. Guess if you need that you’re back to waiting on google
Great ! Thanks for this particularly appreciated convenience. Though living in France, I most often use English versions of native English language softwares, because of quicker updates most often and because of the absence of language barriers when searching for information on a given topic of the software. Firefox included, and your link comforts my position!
Gears 0.5.29.0 actually does work with 3.5.1 if you use the Nightly Tester Tools extension to override compatibility. This wasn’t the case where past versions of Gears were found to be incompatible with new versions of Firefox which is why I’m mentioning it here. You can also re-enable Gears functionality by setting “extensions.checkCompatibility” to “False” in “about:config” although that’s never the best choice. Just remember to set it back to “True” once Google gets their Gears updated…again.
