I have removed cookies, cleared the cache, switched off all extensions (Adblock, Shockwave, and Avast), I have switched off hardware acceleration. Updated my computer and firefox. None of these have had any effect on the issue. Its like ever since they dropped flash nothing works anymore. I am at a complete loss. No one else online seems to be suffering from this problem and I dont know what else I could try. I think I may just have to leave Firefox behind.

Also YouTube is no longer functioning correctly. Sometimes it plays audio but no video, sometimes it refuses to load anything on the page but the video window, and sometimes it refuses to load altogether. ANY possible solutions would be much appreciated.

Suggestion: Downgrade back one version. Is the problem still there?
