Firefox was released today. is a stability release to attention some bugs that surfaced after the recent security update Fixes for this release as quoted from Mozilla below,

  • Bug 400406 - Firefox will ignore the “clearâ€? CSS property when used beneath a box that is using the “floatâ€? property. There is a temporary workaround JS/CSS code available for web developers with affected layouts.
  • Bug 400467 - Windows Vista users will get “Java not foundâ€? or “Java not workingâ€? errors when trying to load Java applets after updating. To fix this, users can right-click the Firefox icon and “Run as administratorâ€?, then browse to a page with a Java applet — doing this once will fix the problem and permanently restore Java functionality.
  • Bug 396695 - Add-ons are disabled after updating. Users can fix this problem by opening their profile folder and removing three files (extensions.rdf, extensions.ini and extensions.cache)
  • Bug 400421 - Removing a single area element from an image map will cause the entire map to disappear. There is no workaround available at this time.
  • Bug 400735 - Some Windows users may experience crashes at startup. There is no workaround available at this time.
