How to remove an add-on that won't uninstall
I have an add-on that has been fine and working in Firefox for a long time. I had been getting updates to the add-on and updates to Firefox. The last time I updated Firefox the little icon for the add-on disappeared from the toolbar. I thought that maybe in the last update that maybe it wasn't compatible and got disabled, but when I looked at the add-on list, there it was plain as day. So, I went to the website of the makers of the add-on and they said that if it wasn't working to uninstall it, but that's the problem I can't uninstall it. When I press the "uninstall" button, I get the "Do you want to uninstall XXXXX? and when I click "Uninstall" to continue the removal it just does nothing. So now I'm thinking, does this mean that I have to completely uninstall Firefox or can I go into the user profile directory and remove a file and manually force a removal.

Which extension are you referring to?
You can try to remove that extension in Safe mode
You can remove the folder where that extension is installed in the extensions folder in the Firefox Profile Folder if uninstalling doesn't work.
Help > Troubleshooting Information > Profile Directory > Open Containing folder
See:
I was trying to remove the 1Password extension. I tried Safe mode, but it didn't uninstall in Safe Mode either. Firefox has been having trouble exiting (it exited in Safe Mode, but not in Normal Mode).
Removing the pertinent .com files from the Profile Folder (see cor-el's post above) seems to have worked well.
