As Revo Uninstaller clears garbage after Programs removal, here is an add-on eCleaner for Firefox that clears preferences left by extensions after their uninstallation.

Haven’t found this type of add-on for browsers like Firefox, Chrome, Opera and IE. Uninstallation of certain add-ons doesn’t clear saved Preferences (thanks to developers of add-ons for this) which does contributes to slow loading of Firefox. eCleaner displays a list of saved preferences by extensions and corresponding stored values in its options.

Clearing Preferences left by extensions after uninstallation with eCleaner

  • Download eCleaner, install and restart Firefox browser.
  • Open Add-ons Manager by clicking Firefox Menu button >Add-ons, locate eCleaner and click its “Options”
  • eCleaner displays saved preferences by extensions with their corresponding values, select add-ons which are uninstalled already or no longer installed for Firefox, and click “Clear Selected” button to let eCleaner do the rest.

Tip: Hold down Ctrl button on the keyboard and select all the extensions one by one and click ‘Clear Selected’ to delete all at once.
