I've been searching for a forum de-blocker for a long time due to the fact I don't feel I should have to register to every forum I end up at from a google search so I can use 1 link then never check the site again. When I saw this the method in which it worked seemed plausible although I don't know much about JS it still seemed like it would work but it DOESN'T. I tried to reinstall several times and restart ff does not work at all. So useless do not waste your time.
