Summary

• This feature provides a way for users to automatically fix Firefox by creating a new profile and migrating their data.

• When the Reset Firefox command is invoked, Firefox will:
  • Confirm with the user what actions are about to be taken
  • Create a new user profile
  • Migrate the user data (bookmarks, history, saved passwords, autofill form/search data, extensions and themes)
  • Reset the toolbars and controls
  • Reset all the user preferences to Firefox defaults
  • Disable all the add-ons and switch to the default theme
  • Restart using the new profile.

• The feature can be accessed three different ways:
  • When the user attempts to re-install Firefox (same version is already installed), he is offered the option to reset Firefox. Note that the reset process is performed by Firefox, not by the installer.
  • After Firefox crashes three consecutive times at start-up, it will offer to either reset Firefox or to start in safe mode.
  • The user can open the Troubleshooting Information page (about:support) and click the Reset Firefox button.

• Since OS X and Linux don't have installers, there is no way to trigger this process for them upon re-installation. The rest of the cases are valid for them too.
