Firefox shutting off add ons

Over the past few days, I've been having an issue with Firefox suddenly disabling and turning off add ons. Specifically, I have the Adblock Plus add on, to block and stop advertisements, spyware, and social media tracking. I will get a behavior in a website I'm not used to getting, like a window asking me if I wish to permit cookies, or sometimes a pop-up ad, and then I'll see that the ABP Stop Sign icon is no longer visible in the toolbar. I will have to go into the Add Ons control page, and click for it to be turned on again, and then go back and reload the page. What is happening here that Firefox is suddenly shutting down add ons? What is the solution to this?

It’s possible that there is a problem with the file(s) that store the extensions registry.

Type about:support in the address bar and press enter.

Under the page logo on the left side, you will see Application Basics. Under this find Profile Folder. To its right press the button Show Folder. This will open your file browser to the current Firefox profile. Now Close Firefox.

Windows: Show Folder; Linux: Open Directory; Mac: Show in Finder

Linux: Under the page logo on the left side, you will see Application Basics. Under this find Profile Directory. To its right press the button Open Directory.

Delete all extensions* files and compatibility.ini in the Firefox profile folder to reset the extensions registry.

New files will be created when required.

After, restart Firefox.

Did you possibly enable Private Browsing mode and your extensions are not enabled in PB mode ?

I'm not comfortable in the least going into any "files" and deleting anything. The last time I did that, I had to do a full and total reinstall from scratch, and lost all of my bookmarks, passwords, settings, and everything else. I only got some of my passwords back because I had physically printed them out a few weeks before. Even then I lost about a quarter of my overall passwords. Never did get any of my bookmarks back. I don't trust the "backup" function, as it doesn't. Doesn't back anything up, that is. I've never had any success reinstalling a backup, because of this "profiles" thing screwing everything up. It doesn't work for me.

I'm getting tired of having to manually go in and reset the thing every time I open up a new browser window.

And no, I've never used PB, so that can't be it. Thanks anyway.

There has to be another fix for this.
