Whenever I try to "clear recent history," which I try to do after every browsing session, I get a message saying "A script on this page may be busy or it may have stopped responding. You can stop the script now, or you can continue to see if the script will complete. Script: chrome://browser/content/sanitize.js:133" I used to get this periodically before I upgraded to Firefox 6.0 but now I get it every time I try to clear my recent history. This happens on both my home and work computers and I'm using Firefox 6.0 and a Windows XP Professional SP2 operating system on each computer. How can I remedy this?

That can be caused by clearing the cookies via Delete browsing, search and download history on Firefox.

  • Firefox/Tools > Options > Privacy > Firefox will: "Use custom settings for history" > [X] Clear history when Firefox closes > Settings
  • Firefox > History > Clear Recent History or Tools > Clear Recent History

Try to exclude the cookies to see if that helps.
Let all cookies expire when you close Firefox to remove unwanted cookies and keep the ones with an allow exception.
Make sure that you do not clear the "Site Preferences" as that will remove all exceptions.

  • Tools > Options > Privacy > Cookies: "Keep until": "I close Firefox"

If you use Delete browsing, search and download history on Firefox to clear the cookies then Firefox also tries to clear the cookies from plugins like Flash and starts a plugin-container process for each plugin and that can add extra time and can cause an unresponsive script error to appear.

I've tried to follow your instructions (although I wasn't sure if your first two bullet points were how you suggest I set my settings or how you thought they may be already set) and will see if this remedies the problem. Thank you for your help.
