Everything was working fine earlier today. I restarted my computer and opened Firefox. The Firefox button has disappeared. I haven't installed any new software. I thought maybe it had been corrupted somehow, so I deleted it and downloaded again. The Firefox button is still missing. What happened? How do I recover it?

You only see the Firefox button when the menu bar is hidden.

Note that a "Reset" creates a new profile and tries to import some settings from the old profile leaving the old profile intact, including the cache folder (about:cache) that can take up to 1 GB.

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:

  1. Go to Firefox > Help > Troubleshooting Information.
  2. Click the "Reset Firefox" button.
  3. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
  4. Firefox will open with all factory defaults applied.


Further information can be found in the Refresh Firefox - reset add-ons and settings article.

At the risk of exposing my ignorance, since I don't have a Firefox button, how do I get to Help>Troubleshooting ?
