Resetting preferences (zoom, tabs, privacy, network, encryption, updates, where to save file downloads, etc.) is one of many procedures that can be helpful in [[Troubleshoot and diagnose Firefox problems|troubleshooting Firefox problems]]. We'll explain two ways to do this.
*If changes to preference settings are not saved when you restart Firefox, see [[Preferences are not saved]].

= Solution 1: Refresh Firefox =
The refresh feature restores Firefox to its default state while saving your essential information. This solution will reset preferences but will also remove other customizations, including added [[Find and install add-ons to add features to Firefox|extensions and themes]]. For more information, see [[Refresh Firefox - reset add-ons and settings]].
=Solution 2: Delete Firefox preference files=
#[[Template:OpenProfileFolder]]
#[[Template:closeFirefox]]
#Locate and delete the file {filepath prefs.js} (or rename it, for example, to ''prefs.jsOLD'', to keep the old file as a backup). If you find more than one, a {filepath prefs.js.moztmp} file or a {filepath user.js} file, delete (or rename) these as well.
#You can close the profile folder and open Firefox now.
