Hello.

My problem is that when I close the FireFox browser I get the "FireFox has stopped working" message. It's pretty annoying. I've read some other posts here that described a similar problem and have tried some of the suggestions in them including:

A clean install, a browser reset, running in safe mode, unchecking hardware acceleration, disabling extentions and plugins one at a time, uninstalling my antivirus (avast), rolling back to version 23.01 and checking run in compatibility mode that someone claimed helped them. None of this was effective.

It seems like after a computer restart the browser will be ok for 2-4 closings and then it will start with the message on every closing. Also, after I uninstalled avast it was good for 6 closings. Rolling back also gave me about 6 message free closings. But then the messages start and doesn't stop.

Is there anything else I can try? Thanks in advance for any suggestions.

Those are problems with the Flash plugin.

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

  • disable a possible RealPlayer Browser Record Plugin extension for Firefox and update the RealPlayer if installed
  • disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)
  • disable hardware acceleration in the Flash plugin

Ok, I added the code to the mms file in the flash folder to disable protected mode and it seems to have fixed the issue.

Thank you very much!!

Best, Tom

All I can add is what worked for me.

https://support.mozilla.org/en-US/kb/firefox-hangs-or-not-responding#w_firefox-hangs-when-you-quit-it

I disabled ALL to do with Java, plug-in and program.

Also, I initially thought the problem was connected to Flash so I followed this advice from another forum:

ABP>Options>uncheck 'show tabs on Flash and Java'

I don't know which has worked but I am now free of that annoying message.
