Every time I try to run Firefox on one of my computers it brings up a UAC dialog and I can't work out why. I've tried uninstalling and reinstalling firefox (more than once) but that doesn't help, and even when I try to run Firefox in safe mode it still
triggers UAC. Does anyone have any idea what's causing this and how I can stop it?
