I clicked block in youtube trying to disable an ad on the video, but now videos won't play at all. I checked my adblock plus preferences and youtube isn't listed as blocked. Help please!

At youtube's home page, thumbnails for videos show up, but when I go to the video itself, it just shows up as a black rectangle. Videos embedded on other sites aren't working either.

See:

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
