Hi, first try restarting Firefox - 3-bar menu > Exit.

Hold down the Shift key when you start Firefox to start in Safe Mode. More - Diagnose Firefox issues using Troubleshoot Mode.

If it's OK in Safe Mode, disable any theme or extensions you have - 3-bar menu > Add-ons > Themes/Extensions, then restart Firefox; now if it's still OK, re-enable them one by one until you find the culprit. You may need to restart Firefox after enabling some extensions.

Note: If you use userChrome.css - you don't have it if you don't know what it is, this is also disabled in Safe Mode, so should be regarded as an additional if unlikely suspect, and can be disabled to test by placing /* before, and */ after the file in the chrome folder, then restarting Firefox.

In case a Refresh has occurred, please look on your Desktop for a file named Old Firefox Data - Refresh Firefox - reset add-ons and settings.

• Profiles - Where Firefox stores your bookmarks, passwords and other user data.

• Recover important data from an old profile.

Firefox may have for some reason, created a new empty Profile. To select your original one, please see Recover user data missing after Firefox update.
