Flash fullscreen multi monitor crash

more options

After updating to the newest version of Firefox whenever I have a flash video in fullscreen on either my main or secondary monitor and I click into another Firefox window Firefox will crash. It doesn't give any sort of error it just gives the windows close or wait prompt.

I have tried turning hardware acceleration on and off updating flash and updating my graphics driver but nothing has solved this issue. It is very annoying because I like to watch videos on my second monitor while browsing websites on my main. I haven't been able to find a solution to this problem so far. If I can't fix this issue I may switch to chrome.

I've called the big guys to help you. Good luck.


If you have problems with current Shockwave Flash plugin versions then check this:

  • see if there are 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)

Here are the last few recorded crashes. This problem occurs far more often than the crash records indicate. Also I tried disabling hardware acceleration within firefox and not just the flash plugin now the issue has been solved for some sites(Youtube being the prime example) but the problem still persists on others(like Twitch.tv)

The crash report flagged these programs;

Process Type plugin Shockwave Flash Version:16.0.0.305


Start Firefox in Safe Mode {web link} 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?

When browsing in safe mode the Use Hardware Acceleration option was already disabled and whenever I click to another monitor(in safe mode) It just takes me out of full screen on the other. This solves the problem but only when safe mode is on which is not ideal for daily browsing.
