A few weeks ago, my Firefox browser became unusable. I do not know what caused this to happen. When I went into Firefox, the first thing that I noticed was that my bookmark toolbar was gone. The next thing I noticed was that typing something into the search field and clicking enter produces no result. And then, of course, the main and largest problem was that typing something into the address bar also produced no result. I could not visit any web pages with Firefox. At this point, I was forced to use Chrome.

I ran a full virus scan with Bitdefender (free version) and I also ran MalwareBytes. It did find a PuP: GeekBuddy, which I proceeded to remove. This did not solve my problem. I then uninstalled and reinstalled Firefox, this did not solve the problem. I then tried to disable my firewall and virus services to see if I could access web pages from Firefox: I could not. I tried the troubleshooting steps provided by Firefox such as restarting in Safe Mode and Refreshing, this did not fix it. I then decided to try something else. I uninstalled Firefox and I then ran CCleaner, the registry cleanup from CCleaner. I removed all of the old registry entries etc. I then restarted and ran it again. I then installed Firefox. At this point, I was able to use Firefox again.

At this point, I can use Firefox but I cannot change any of my default settings: such as to change my home page, to not remember history, or to change my default search provider, which is currently defaulting to Yahoo. If I change any one of these settings, Firefox opens up and is totally unusable as before. I have to Refresh Firefox to get back into action with Firefox.

In addition, I cannot install NoScript, if I do that I also see that my Firefox is totally unusable as before and I have to Refresh Firefox again. I am really upset about this, I do not know if my browser has been hijacked somehow. How can I clean up my Firefox completely and stop all of this aberrant behavior?

Thanks in advance for your help.

Note: Some software, like Advanced SystemCare with Surfing Protection, can protect files in the Firefox profile folder against changes. If you have such software then check the settings or uninstall this software.

Thanks for the link, I will read over this page to see if I can get any ideas. UPDATE: actually, each time I launch Firefox, it launches as unusable and it has nothing to do with my preferences or add-ons....it just launches that way at each start-up. I can then Refresh Firefox and it starts working again.

So is everything okay now?

Try to rename/remove the xulstore.json file in the Firefox profile folder.

You can also check for problems with preferences.

Delete possible user.js and numbered prefs-##.js files and rename/remove the prefs.js file to reset all prefs to the default value including prefs set via user.js and prefs that are no longer supported in current Firefox releases.

You can use this button to go to the current Firefox profile folder:

Let me try this from cor-el, thanks! Hoping it solves this problem. Still working through these issues in my scant spare time.
