@Sander Lepik - I am not sure if you're directing your comments at me or not, but I didn't create this addon. Since TWC appears to have forgotten about it, I have been trying to fix it when new versions of Firefox come out since I use it myself. You cannot use the version here on Firefox greater than 3.x, it will not work due to changes in the way addons are handled. You must download it from this link for versions greater the 4.x:
If you don't trust that code, that's fine because in my previous "reviews" I describe how to fix it manually. I also use this on Linux so I know it works.
