Youtube is pretty shit nowadays. If you want your video to buffer past 50 seconds, you need to change the quality, then change it back. This is actually the official solution posted on the youtube forums, and it was posted 2-3 years ago.
Also, if the video has a 3D option, or 144p option, that trick won't work, so it just won't buffer. Especially the 144p option, it won't buffer while paused, and the quality will fluctuate between awful and worse no matter what you set it as.
The layout is just completely awful, I actually had to combine two greasemonkey scripts and edit the hell out of them just so I could get a nice looking youtube, and it still didn't fix everything. But my pride and joy is a video page, fully centered with a gray background, with a medium sized video player that I can actually see.
