There are a few things you can try:

• Update Firefox: Update Firefox to the latest release
• Update your Graphics Driver: Upgrade your graphics drivers to use hardware acceleration and WebGL
• Consider updating to Windows 10 (though that won't likely change this issue).
• Refresh Firefox Refresh Firefox - reset add-ons and settings

I have already tried all of that, no updates, latest version of firefox (v44) doesn't change anything, and I'm on windows 8.1, and refuse to go to windows 10 untill I know that it's not broken

Does Firefox crash or does Windows only crash?

Just Windows crashes, I have a duel monitor setup on my laptop, and I can see that Firefox is still open when the blue screen occurs because it only occurs on my main screen

I might also Note that 60fps works on Chrome just fine, but not sure if Hardware Acceleration is on in Chrome

The dual monitors might have something to do with it, but what sort of hardware are you running them on? AMD/Nvidia/Intel? Model(s)?

Meanwhile, I found this solution from not too long ago that has similar features: https://support.mozilla.org/en-US/questions/1090298. The rest were really old issues that got fixed with software and driver updates or by disabling Flash's hw acceleration or add-ons. One case was helped by a fresh profile. W8 kept cropping up in the issues, but they were probably from when it was first released and still problematic.

I have an Intergrated AMD Radeon R5 and I have had the problem of hardware acceleration blue screening since I got the computer, I have only recently gotten a second monitor

The crash occurs on BOTH flash and Firefox Hardware Acceleration, and I have already tried a fresh profile, the real problem I have is why I can't get a decent frame rate on youtube vidoes anymore

I have the same setup in my laptop, R5 with Windows 8.1. No bluescreens though, and no dual monitor (I use a 24" monitor for work, but always disable the laptop display when I do).

If you can't get decent FPS without hardware acceleration, then the CPU is probably too low power for the rendering options used in Firefox. Chrome getting all the way to 60 sounds like HWA is on.

Did you try tweaking Firefox settings (in the link for starters) to get HWA not to bluescreen?

No Idea how, or what HWA is, mind filling me in?

Also, my computer is an AMD quad-core A8 with 2.00GHz

Sure; HWA is just shorthand for hardware acceleration. As luck would have it, mine is also a 2 GHz A8 (A8-6410) and it is an utter slug, never mind the core count. It's about as budget as decent budget processors get.

well, enabling hardware acceleration in firefox causes my whole computer to crash, so I don't want to test that right now, but I used to be able to get 30fps no problem, but not anymore for some reason, especiall in fullscreen, the frame rate drops down to about 10 or less

I pulled up the "stats for nerds" in htm5 on the same video, on the same quality (720p60fps) on both Firefox and Chrome, I don't know what it all means, but maybe it can help.

The one in chrome is the one with in mime type video/webm

Just a Note I switched to Flash player on Firefox, after updating it to the latest version, it still can't do 60fps on any videos, but I at least get a stable frame rate, but I would like to solve my issue still, because flash is made up into squares, and they are very easy to see, and very annoying, plus, they sometimes get cut unevenly so parts of the video will not line up properly

The thing that immediately strikes me is that FF is using WebM and Chrome is using MP4. Can you try disabling WebM in Firefox to see if MP4 is more effective for you?

To do this, go to about:config and toggle media.webm.enabled. I tested this on my Firefox and it switched rendering from WebM to MP4.

Actually, it's the other way around, chrome is the one with more bold text, and it's using WebM

OH... I assumed it was Firefox because of all the Dropped Frames and larger frame count (since we're troubleshooting FF). Those are frames your system is too slow to render so they drop out of the pipeline, never to be seen. 1-2% drop is not horrible, but for all intents and purposes it should be 0%.

You can try the toggle with MP4 in that case, the value to toggle is media.fragmented-mp4.enabled.

PS. There are apparently quite a few MP4 settings, so trying until you get it is the way to go.

PPS. I was curious and looked up the video (The Boston Wanderer LP of FO4). It is definitely clunky with MP4, but while WebM drops frames just as horribly, the viewing experience is much smoother!

toggling media.fragmented-mp4.enabled to false causes HTML5 to start with an error (picture) and then it immediately switches to flash.

Disable what you don't want, Flash included (unless you for some reason like Flash).
