Hello,
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 and some Preferences.
- Open websites will not be saved in Firefox versions lower than 25.
To Reset Firefox do the following:
For Firefox versions previous to 29.0:
- Go to 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.
For Firefox 29.0 and above:
- Click the menu button
, click help 
and select Troubleshooting Information.Now, a new tab containing your troubleshooting information should open.
- At the top right corner of the page, you should see a button that says "Reset Firefox". Click on it.
- 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.
Further information can be found in the Refresh Firefox - reset add-ons and settings article.
