I use Firefox as default browser on my Mac. For some reason I can't play Youtube videos anymore. Facebook videos work, and Youtube videos play fine in Safari. If I restart with all addons disabled, it works again. Then if I enable addons one by one, it works up til a certain moment. Then I disable the last addon again, but no luck. Then I disable all addons manually, and still no luck.
What happens is I see a black screen with "static". See the image:
So I'm a bit lost here. What is the best way to solve this? How can I get this working again? Below the list of the addons I have installed.
