Firefox crash on youtube. Safe mode works, reinstall doesn't
I've been having a lot of trouble with youtube in FF on and off for a while now. I noticed if I run FF in safe mode, it works without any problem, but normally playing a youtube vid (even embedded in another site) can cause my display driver or even my pc to crash. My driver is fully updated, and was reinstalled cleanly. I tried refreshing FF and it didn't help. I uninstalled FF completely, even manually erasing any trace of any file/folder that had firefox or mozilla in it. Reinstalled and still the same problem continues.

One of your add-ons may be the trouble maker.
Type about:addons<enter> in the address bar to open your Add-ons Manager. Hot key; <Control>(Mac:<Command>)<Shift> A)
In the Add-ons Manager, on the left, select Extensions. Disable a few add-ons, then Restart Firefox.
Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Disable All of them.
If the problem continues, disable some more (restarting FF). Continue until the problem is gone. After, you know what group is causing the issue. Re-enable the last group ONE AT A TIME (restarting FF) until the problem returns.
Once you think you found the problem, disable that and re-enable all the others, then restart again. Let us know who the suspect is detective
You can try to disable hardware acceleration in Firefox.
- Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
You need to close and restart Firefox after toggling this setting.
Also make sure that you have the latest updates of the graphics display driver.

Its an HTML5 player not flash one, although it happened with the flash player as well. Hardware acceleration on/off doesn't help, and like i already said all my drivers are updated.
Also like i said, i refreshed FF, so I have no extention, no themes, no nothing. Besides Plugins, which some I can't uninstall, its as clean as it can possibly be.
You could try disabling Flash plugin's protected mode. The protected mode feature of the Flash player plugin has security benefits, but seems to have compatibility issues on some systems. There is a new hidden setting for this: (A) In a new tab, type or paste about:config in the address bar and press Enter. Click the button promising to be careful. (B) In the search box above the list, type or paste flash and pause while the list is filtered (C) Double-click the dom.ipc.plugins.flash.disable-protected-mode preference to switch its value from false to true. This might not take effect until all Flash has been unloaded for a few minutes, or you close Firefox.
1) Enter the config by typing about:config in the address bar. 2) Enter media.mediasource.webm.enabled and press enter. 3) Right click on it and change to true, for some reason it is set as "false" which makes MSE & WebM VP9 not work properly. 4) Visit: https://www.youtube.com/html5 and check that everything is OK. 5) Try to watch a video. It should work now.

well I tried enabling MSE & WebM VP9 like you said, and its like it makes it work on every other vid.... I try a random vid and it seems to work fine, then i go to my sub-box and try a vid there, and it crashes before it even loads a single frame.... :(
I've called the big guys to help you. Good luck.
