• Firefox 4.0.1 giving "TypeError: components.classes['@ [cid] is not defined. How can I fix? Other posts about it did not solve my problem.

  I started Firefox in Mode safe mode with no addons, extensions or themes active. And it still happens. I noticed Greasemonkey is installed but can find no way to remove it - but no scripts are installed in it.

  I use AVG Antivirus and have read the web-protection component could cause this problem but have not read how to correct it. Any info would be greatly appreciated.

  Occurs whenever I open Firefox for the first time and every time I open a new browser window. Coming as at any time a web page generates a popup window. Can't when I just open a new tab or link in a new tab.

  Do a clean install (re)-:

  • Download a new copy of Firefox and save the file to the desktop.
  • Firefox 4.0.x: http://www.mozilla.com/en-US/firefox/all.html
  • Uninstall your current version of Firefox and remove the Firefox program folder before installing this copy of the Firefox installer.
  • Do not remove the data of a personal nature if you uninstall the current version.
  • It is important to remove the Firefox program folder to delete all the files and make sure that there is no problem with the files that were the remains after uninstallation.
  • It is perhaps not necessary to create a new profile, so first try if it works with your current profile, and if not then create a new profile.

  Create a new profile as a test to see if your profile is the source of the problems.
  See:

  • Basic troubleshooting: make a new profile

  There may be extensions and plugins installed by default in a new profile, so check that in "tools > Modules > Extensions & Plugins»
  
  If this new profile works then you can transfer files from the old profile to the new profile (be careful not to copy corrupted files)
