It makes using the browser kind of impossible. Any ideas? Chosen solution The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences. To Reset Firefox do the following: Go to https://support.mozilla.org/questions/944619 Firefox > Help > Troubleshooting Information. Click the "Reset Firefox" button. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish. Firefox will open with all factory defaults applied.
