Firefox 16, the latest version of Mozilla’s popular web browser, was recently released - and swiftly pulled owing to a major security flaw.
Mozilla claims that “the vulnerability could allow a malicious site to potentially determine which websites users have visited and have access to the URL or URL parameters.”
At present the company has no indication that the vulnerability has been exploited anywhere in the world.
As a result of this flaw, Firefox 16 has been pulled from the internet for the time being. Head on over to the Firefox download page and you’ll still only be able to download Firefox 15.
Mozilla advises any who downloaded and are using Firefox 16 to roll back to Firefox 15. There are instructions on how to do so here. Alternatively, Firefox 16 will be automatically patched to eradicate the vulnerability.
Firefox 16 has a number of fixes and improvements, along with a couple of new features - mainly aimed at developers. For example, there’s a “New Developer Toolbar with buttons for quick access to tools, error count for the Web Console, and a new command line for quick keyboard access.”
On the regular user front, there’s now web app support for all three supported operating systems - Windows, Mac and Linux - and Mac owners can expect VoiceOver support as standard.
Firefox is the second most widely used web browser in the world after Microsoft's Internet Explorer, although Google's Chrome is practically level according to recent figures. Both represent around 20 per cent of internet traffic according to recent figures. High profile security issues like this won't be helpful in such a close-fought battle.
