For over a month now Waterfox with YouTube has been working on and off. Videos longer than 6 minutes would start to bug out and eventually stop working. Corrupted frames would appear, and trying to skip ahead in the video was just asking for it to break. Not til recently did more stuff start to break. yesterday my webm support went cactus. A webm file will just sit there loading, the same as a YouTube video. Plugin Container.exe doesn't crash anymore, because it doesn't even start up. As a result none of my addons work, yet playing video in waterfox safemode works. I've tried disabling individual addons and all that, and nothings different. Uninstalled all my plugins, etc etc.

Firefox works fine, and weirdly enough, Waterfox safemode too. What happened to my plugin container?
