My add-ons are not working even though they are "namely" enabled. These include among others "Better Privacy" and "NoScript" (those are basically the ones I'm concerned about). I go to the add-ons window, they seem to be enabled, when I click the options button the whole window freezes and I have to close it through task manager. I tried disabling them - restart Firefox - re-enabling them - restarting Firefox --- no good. Reinstalled Firefox --- negative. I also went to help-> troubleshooting information and they are all marked as enabled. Nevertheless, neither of them is working: No NoScript icon, no script blocking, no Better Privacy pop-up when I exit the browser - nothing. The next step would be to completely remove and do a fresh installation. But I'm wondering what caused this.

Thanks.
