Adobe Flashplayer crashes once any video is started

Question

As of today, I cannot watch any videos because Adobe Flashplayer crashed upon beginning any video.
I had nightly. Uninstalled it and then installed the regular firefox. Didn't help
Started in Safe Mode. Didn't help
Reinstalled Flash. Didn't help
Installed slightly older version of Flash. Didn't help
Even better yet, whenever I try to access trouble shooting information in firefox, the browser crashes every time without fail. I'll try to make a manual list of plugins and addons for you though.
I'm writing this from Chrome right now. Videos work here
Pic of error if there's any confusion

Answer 1

Can you access Troubleshooting Information in Firefox's Safe Mode? That's a standard diagnostic tool to bypass interference by extensions (and some custom settings). More info: [[Troubleshoot Firefox issues using Safe Mode]].
Two ways to invoke the Safe Mode dialog:
(1) If Firefox is running,
Help > Restart with Add-ons Disabled
(2) If Firefox is not running, hold down the Shift key when starting Firefox
In the small dialog that should appear, click "Start in Safe Mode" (''not'' Reset)
Any improvement?
If so, before returning to normal mode, please disable Firefox's use of hardware acceleration for graphics. This feature works with most graphics card drivers, but driver updates sometimes reveal a severe compatibility problem.
orange Firefox button (or Tools menu) > Options > Advanced
On the "General" mini-tab, uncheck the box for "Use hardware acceleration when available"
This change takes effect after you exit and restart Firefox.
