Adobe Flash Player keeps Firefox process active even after closing the window

Symptoms: When RE-starting FireFox, this msg appears and FireFox does NOT restart: "FireFox is already running but is not responding"

Causes: It happens if and only if, initially, FireFox used the FlashPlayer. It is the FlashPlayer process that keeps the FireFox process hanging and active even after the FireFox window get closed. In fact, after closing the window, I see both processes (FireFox & FlashPlayer) still active. When I kill the FlashPlayer process, the FireFox process terminates also.

If FireFox does not open the FlashPlayer, everything goes fine (the symptom does not occur).

QUESTION: Is there any known way to fix this problem?

The FlashPlayer is 11.0.1.152-0lucid1

For a quick and dirty fix, open a text editor, and copy&paste the following text( no parentheses around hash symbol - just needed to render this post properly ?)

(#)!/bin/bash

killall firefox-bin &&

firefox &

exit


Save as firefox-fix.sh and make it executable (chmod +x firefox-fix.sh)

If you are using Gnome, you can make a custom application launcher...

Type:Application

Name:Firefox-fix

Command:bash firefox-fix.sh

Comment:Flashplayer Plugin Fix

Works for now, until a permanent fix is found!

Thanks. But I resolved the problem two weeks back by installing Firefox 7, which does not exhibit that problem.

I installed 7.01 for Ubuntu 10.04LTS(lucid) with no joy.

Still the same problem requiring the killing of the running process. I'm back to using a modified script and launcher, but I must say I'm happy with 7.01 in general....Thanks!
