Install or Upgrade to Firefox 3.6.6 in Ubuntu Using PPA

The much anticipated Firefox 3.6.4 was released some days ago and within days, another important updated release of Firefox called Firefox 3.6.6 is ready for download. As we have already seen in our Firefox 3.6.4 review, Firefox 3.6.4 is the last major release before the eventual Firefox 4.0.

What's New in Firefox 3.6.6?
  • Firefox 3.6.4 provides uninterrupted browsing for users when there is a crash in the Adobe Flash, Apple Quicktime or Microsoft Silverlight plugins.
  • Or in other words, 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. 
  • And Firefox 3.6.6 modifies the crash protection feature in Firefox 3.6.4 to increase the amount of time that plugins are allowed to be non-responsive before being terminated.
