Firefox 3.6.4 provides uninterrupted browsing for Windows and Linux users when there is a crash in the Adobe Flash, Apple Quicktime or Microsoft Silverlight plugins.This new feature is plugin browser crash protection. What happened earlier was when Flash or Quicktime crashed in the browser, it would take the entire browser down with it Firefox 3.6.4 changed it so that non-responsive plugins crash the plugin, not the browser, after 10 seconds.
If a plugin crashes or freezes, it will not affect the rest of Firefox. You will be able to reload the page to restart the plugin and try again.
This move was much anticiapted becasue many users found that they couldn?t play FarmVille, which runs on Adobe Flash consequently FarmVille was crashing very often so in firefox timeout for unresponsive plugins was increased from 10 seconds to 45 seconds, giving the hefty Flash-based game enough time to properly load.
Firefox 3.6.4 also fixes the following issues found in previous versions of Firefox 3.6:
