Mozilla Yanks Firefox 16 Over Security Concerns

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.

"The vulnerability could allow a malicious site to potentially determine which websites users have visited and have access to the URL or URL parameters," Mozilla said. "At this time we have no indication that this vulnerability is currently being exploited in the wild."

Firefox 16 made its debut on Monday, and the update largely focused on new developer tools. That included a developer command line, which Mozilla showed off in the video demo below.

On mobile, Firefox for Android got Reader Mode, which made it easier to view, read and share articles and stories from your mobile phone or tablet. To use, tap the "Reader" icon in the Awesome Bar.
