Add-Ons Problem
So I've been having a problem with Firefox. Every time I open Firefox the last add-on on the taskbar is grayed out and doesn't work properly, it also makes it impossible to open any website, it just load infinitely. I have disable/enable the last add-on on my task bar in order for Firefox to work properly. It's really annoying and it just started to be like that for about 2 week.

Ok, the problem was solved by creating a new profile. All of my extensions are working correctly.

I forgot to add an image of the task bar. And it doesn't matter which add-on is the last one, it's always grayed out every time I re open Firefox

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.
See "Corrupt extension files":
+++++++++++++++++++++++++++ You will have to approve the updating one last time.
OK I tried doing that and reinstalled all add-ons that I had. It looks like there is a problem with uBlock Origin and One Tab. Will see if those two have a support page or I don't know what else to try. One Tab and uBlock are showing grayed out like I sent in the screenshot above.
Keep us posted.

Go to that message, and use the Undo link to its right.
Still no fix from OneTab or uBlock. Will keep replying if something helps
