A few more crash reports if that helps. Also, when ever it crash Firefox goes to full screen and I need to turn it off (F11).

That are crashes with the Shockwave Flash plugin

You can check for problems with current Shockwave Flash plugin versions and try this:

• check for updates for your graphics drive drivers
  https://support.mozilla.org/kb/upgrade-graphics-drivers-use-hardware-acceleration
• disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)
• disable hardware acceleration in the Flash plugin

See also:

• http://kb.mozillazine.org/Flash#Troubleshooting

• check for updates for your graphics drive drivers
• https://support.mozilla.org/kb/upgrade-graphics-drivers-use-hardware-acceleration

Already done, and have latest.

• disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)

I switched "dom.ipc.plugins.flash.disable-protected-mode" from false to true.

• disable hardware acceleration in the Flash plugin

Only found how to do the disable-protected-mode and found nothing else on this.

And it still crash.

Having chrome running and running flash does not crash it when Firefox crash(Chrome never crash). It's happen when I play videos and running anything with flash. And because the Internet run with the hateful flash I can't just avoid it, no mater how much I really want it to be gone.

To disable hardware acceleration right click on a video and choose settings it should open up a tiny box with that option. You can try cleaning the registry and reinstalling flash. For this you will need Ccleaner (https://www.piriform.com/ccleaner). When you finish installing Ccleaner, close Firefox, uninstall flash, use Ccleaner to clear registry, restart the computer, reinstall flash, when Firefox opens go to Addons>Plugins and set flash to "ask to activate". I had the problem with flash crashing Firefox before, it has to do with it being updated improperly by an anti-virus, or some other third party app.

Yes, currently there is also some investigation going on on Adobe's end for now I would recommend what forgottengods mentioned above:

• From the Firefox menu choose "Add-Ons"
• Chose the "Plugins" category
• Switch "Shockwave Flash" from "Always Activate" to "Ask to Activate"

Tried to reinstall flash, it looked like it was working, but after a while it still crash. But I think it's not flash that does this, I didn't have flash running afaik. Firefox has crashed 9 times in the last 2 days, and none have created an crash report sins I reinstalled flash.

It sounds like there may be crash reports in the plugin itself: Send plugin crash reports to help Mozilla improve Firefox

Otherwise can you please try browsing in Safe Mode for a while until it crashes again? These reports should clear up if it is no longer a flash issue since you reinstalled it: Diagnose Firefox issues using Troubleshoot Mode

Still crash in safemode, this is the error message I get, with no crash report, I assume it's flash thats still crashing?

Edit: It also seems like they come in group. If it crash once, it's going to crash 10-20 times in the next hour.
