Check plugins page never loads.
Beginning today, I can no longer watch YouTube videos without them freezing. They will usually start with an ad that doesn't play or load. Then if I wait a few seconds or click on the video, the video just starts playing. Then, the video will play for a few minutes before freezing. It doesn't start again if I reload. I have uninstalled and reinstalled Firefox, Flash, Shockwave, RealPlayer, and Java. I have disabled hardware acceleration. I have tested and verified that Flash, Shockwave, and Java are working. I installed the add-on to make all YouTube videos play in HTML5 because when I went to check that the HTML5 video worked fine and the non-HTML5 video didn't, but the rest of the YouTube videos still don't work and give me the same problem. When I go to check if it is a problem with my plug-ins, the page to check my plugins never loads. It either simply stays a blank page or it will say it's checking and never brings back any results.

Try to create a new profile as a test to check if your current profile is causing the problems.
See "Creating a profile":
- https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles

If the new profile works then you can transfer some files from an existing profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over the problem
