Firefox v20.0.1
Greasemonkey v1.8
Bob v5.2.4
Conquertell4 v1.0.3
This morning everything was working fine. Later I decided to make some space on my hard drive by deleting some old videos and pictures using File Shredder. While they were being shredded I clicked back to Firefox, where I had several tabs open and tried to view my games. The page wouldn't load then a box opened up asking if I wanted to disable a script on the page or continue (or words to that effect). This has happened a few times before, but usually only when my computer is running slow and I'm trying to load one particular game that has been going on forever. Anyway I clicked continue (at least I think I did because that's what I generally click on) and eventually the page loaded, but was displaying as if BOB wasn't installed. I can't click on any of the in-game snapshots I have previously taken as the links don't work and appear as a jumble of characters and Bob has completely disappeared from the side menu.
I checked to see if the user script was still installed and enabled and it is along with Conquertell which is still working as normal. I then checked Greasemonkey and that is also enabled, except now I don't have the monkey icon at the bottom of my page like before. I did notice that there was a newer version of GM so I installed that but this didn't fix the problem, Nor did unintsalling/reinstalling BOB and GM or clearing the cache and deleting cookies etc.
Finally I tried uninstalling everything again including Firefox (while keeping my profile, because I didn't want to loose my bookmarks etc) and reinstalling, but still no joy.
Since I'm not very computer savvy I have no idea what else I can do, so any help/advice would be much appreciated.
Thanks!
