Flash plugin crashes everytime I touch a key on the keyboard.

Question

I've tried Safe Mode but I get the same issue. Firefox is updated and so is Flash.
It happens 100% of the time on YouTube, but not every site that uses Flash.
I've tried fresh installs, reinstalling graphics drivers, safe mode, new users, hardware acceleration, you name it.
This has been happening since last December.

Never be annoyed by a Flash animation again! Blocks Flash so it
won't get in your way, but if you want to see it, just click on it
If you have problems with current Shockwave Flash plugin versions then check this:
* see if there are updates for your graphics drive drivers

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

* disable hardware acceleration in the Flash plugin

While you are in safe mode;
Type '''about:preferences#advanced'''<Enter> in the address bar.
Under '''Advanced,''' Select '''General.'''
Look for and turn off '''Use Hardware Acceleration'''.
Poke around safe web sites. Are there any problems?
