Maybe this will help? Adobe Flash plugin has crashed - Prevent it from happening again

If not, then it might be helpful if you could furnish some recent crash Report IDs

1. Enter about:crashes in the Firefox address bar and press Enter. A Submitted Crash Reports list will appear, similar to the one shown below.
2. Copy the 5 most recent Report IDs that start with bp- and paste them into your response here.

Thank you for your help!

I found a solution to the flash player crashes within Firefox, and have not had a single flash playser crash in 6 months at least. The solution involves creating a task to run at regular intervals to delete certain prefetch files. NOT all of them as it is NOT necessary to delete them all.

I have wrote a script that will create the folder structer in programdata/scripts/ and place the exe that actually does the deleting, and have successfully imported the task into task scheduler.

This should resolve all Flash player crashes within Firefox. I posted the information here: https://support.mozilla.org/en-US/questions/968190?page=6#answer-51113 2

That script is not 100% Automated in the above link, but will get you started.

I have one that i have been able to fully automate, You would just need to check task scheduler in Windows 7 to confirm it will successfully import on its own.

I am looking for testers to confirm this works. This should work on windows 7 64 and 32 bit. Not tested on Windows 8
