Adobe is working on a new sandboxed version of the Flash Player browser plugin for Firefox. The move will make it tougher to compromise a system's security using malicious Shockwave Flash objects. The new plugin for Firefox (and other browsers like Opera, which rely on the common Netscape Plugin Wrapper model of browser plugins), will work essentially similar to the Flash Player Google Chrome ships with, which works in a "Protected Mode". When "sandboxed" Shockwave Flash objects in webpages will work as separate processes, with much lower privileges than the actual user, the user's machine environment will be kept abstract to it. Adobe has already redesigned the browser plugin of its Reader X (PDF viewer) to work this way, and hasn't seen a significant successful exploit since November, last year.
