One of my Firefox extensions, specifically, one called FiddlerHook, is currently disabled and has no remove button. It has a note that it's unverified, so I want to remove it, but there is no Remove button. How do I go about removing it?
Following the instructions given in this answer, I went to my extensions folder to delete it that way, but about half of the extensions there are represented by GUID names. Since FiddlerHook isn't among the ones that I can see among the more plain text names, I'm assuming that it's one of the GUID ones, but I don't want to delete the wrong one. I tried loading one of them into a text editor, and it looks as though they're executables of some kind (I saw PK followed by a bunch of gibberish), so that didn't help me figure out which one it is I have to delete.
Taking SleepingGod's advice, I went to the official documentation, and that said that there should be a .xpl file or a filder with the same name as the extension's ID. In the case of FiddlerHook, that ID is [email protected], but there's no [email protected] file or [email protected] folder in my extensions folder. A thorough search of my entire C drive also came up empty. Restarting Firefox in safe mode was of no help, because even in that mode, that extension doesn't have a remove button in the Extensions Manager.
Would there be anything in the registry that would be causing that extension to show up as an entry in the Extension Manager even though there is no .xpi file for it?
