Sandboxed Flash Player for Firefox Now Available in Beta Form

Adobe on Monday announced the availability of Flash Player Protected Mode for Mozilla Firefox . Essentially a sandboxed version of the popular browser plugin, Flash Player Protected Mode for Firefox is currently in beta. Hit the jump for more.

The popular plugin is no stranger to sandboxing technology, having supported sandboxing within Chrome for over an year and in Internet Explorer for longer than that. Back in late 2010, when Adobe first enabled sandboxing support in Chrome’s integrated Flash Player, the company had hinted at the possibility of the technology being extended to other browsers.

“Today, Adobe has launched a public beta of our new Flash Player sandbox (aka “Protected Mode”) for the Firefox browser,” announced Peleus Uhley, a senior security researcher at Adobe, in a blog post. “The design of this sandbox is similar to what Adobe delivered with Adobe Reader X Protected Mode and follows the same Practical Windows Sandboxing approach. Like the Adobe Reader X sandbox, Flash Player will establish a low integrity, highly restricted process that must communicate through a broker to limit its privileged activities.”

“Sandboxing technology has proven very effective in protecting users by increasing the cost and complexity of authoring effective exploits. For example, since its launch in November 2010, we have not seen a single successful exploit in the wild against Adobe Reader X.”

This particular Adobe Flash Protected Mode implementation requires Firefox 4.0 or later and supports both Windows Vista and Windows 7. The beta is available at the Adobe Labs site .
