No, i am not.
What other files the 'flash-tracer for firefox' is realeted?
The problem start when i did install it.
I did the update it, and does not goes away. I did uninstall the entire firefox, and did not goes away.
I did uninstall the flash player and then i just pay attention that is goes away with flash player version untill 10.1.
Can you check if mm.cfg is present for the admin user? (Or whatever user Firefox was installed with (probably elevated to admin)).
Another thing to consider is the virtual per user temporary filesystem mapping that Vista/Win7 does. Try going to C:\Users\User_name\AppData\Local\VirtualStore\ and see which files are present there.
