UPDATE (October 15, 2014): Solution did not work below. Updated Flash using the directions here: https://support.mozilla.org/en-US/kb/adobe-flash-plugin-has-crashed. We’ll see and keep you posted.
I was having continuous crashing problems with the Firefox Quicktime/Flash plugin. Visiting Flash enabled websites would cause Firefox to crash and display the dreaded crash image above.
I tried uninstalling Firefox completely and reinstalling, but nothing worked.
I’m unsure how I thought of the solution below, but it’s been working ever since. To fix Firefox from crashing due to the Quicktime/Flash plugin, follow these steps:
- Go to Options (select the lined button on the top right of browser)
- Go to Applications tab and scroll down to Shockwave Flash Object
- In the dropdown under Action change both ‘Use QuickTime Plug-in 7.7.5 (in Firefox)’ to Use Adobe Flash Player 10.0
- Click Ok
The crashing should stop.
