Google Chrome’s ability to keep a browsing session afloat, even if one of the webpages were to crash is really impressive. What I mean to say is that if one page goes down it doesn’t take the entire session down with it.
With the new Release Candidate, Firefox tries to achieve the same functionality through its crash proofing and plug-in isolation mechanism. So let’s say, you were watching a flash video and the flash plugin crashes. Unlike, previous versions of firefox which would react to this by crashing the entire browser, the 3.6.4 release candidate isolates the flash plugin page and preserves the rest of the browsing session.
This Release Candidate is available for Windows, Mac and Linux users. You can download it from here.
