Extremely Laggy YouTube Performance After Update To Version 157.0

Turning off Ghostery solved it for me. Hopefully there will be a fix soon, but until then Privacy Badger will have to do the heavy lifting on Youtube.

I had to uninstall 157 completely, and then install 156 again (make sure you have an account with Mozilla before you do this so you can get back all your info easily). 156 is at least usable... but barely. Here's what is still happening: -Clicking a video typically you get about 10 seconds of nothing before the page loads. -Sometimes it's just audio for another 10+ seconds. -If you open the video to full screen it takes at least another 10 seconds to actually get full screen, usually showing the normal looking video with all the other videos and video info but "full screen" -When it finally gets full screen, strap your patience hat on because if you press the forward arrow to fast forward 5 seconds, it's going to be on a 2 second lag at least. Everything you do is on a lag. - If you close out tab because technology not working the way it should is literally the most frustrating thing on the planet prepare for the video to play audio for another 5-10 seconds after closing it. This sucks guys. Usually the updates are pretty meh, unnoticeable, but this is some actively BAD stuff.
