Mozilla on Wednesday yanked the most recent version of its Firefox browser after discovering a security vulnerability that could provide scammers with access to your browsing history.
Firefox 16 was removed from the current Firefox installer page last night. Those who have already been upgraded will get the patched version as soon as it's available, Mozilla said in a blog post. If you're worried, there's the option to downgrade to Firefox 15.0.1, which is not affected by the bug.
Mozilla said it is "actively working on a fix" and plans to ship an update sometime today.
