Summary

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