Public beta of Flash Player sandbox for Firefox is out

A little over a year after the implementation of a Flash Player sandbox into Google Chrome, Adobe has announced the release of a public beta of its new Flash Player sandbox for the Firefox browser.

“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,” shared Peleus Uhley, Adobe’ platform security strategist.

The sandbox is designed to protect the browser from attacks exploiting Flash vulnerabilities, and the Adobe Flash Player Protected Mode for Firefox 4.0 or later will be supported on both Windows Vista and Windows 7.

“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,” says Uhley, and added that the final version of the sandbox is due to be released later this year.

Firefox is the first browser for which Adobe engineers have developed a sandboxed version of Flash, as Google’s developers did the implementation for Chrome.
