I've read a few different posts about this problem, but the ones I've seen just tell you to restart firefox through Taskmanager. Whenever I close portable firefox, and make sure that it's not running in Tskmngr, it STILL will not recognized that it has been restarted. Even when I unplug my flash drive and replug it in, it will not install my extensions. Does anyone know what I need to do? Reinstall PFF? Or is it a glitch?
