Userscripts not showing up

I have firefox 20.0.01 installed and greasemonkey 1.8 - latest versions of each.
Also a number of user scripts.
They are all marked as enabled but none of them are showing up in my games or the gamefinder page. Also when I try to reinstall BOB I just get the userscript.
I tried downloading chrome but it tells me I can't get BOB as I can only download approved extensions through the google chrome apps store (or whatever it is called on chrome).
Am I missing something obvious?
