Awesome addon! Thank you to the developer.
When I first installed this addon, my browser crashed every time I tried to use it just like the user below. I isolated the problem to the Session Manager addon. I now use the session manager in Tab Mix Plus. No more crashes.
By the way, I have about 70 addons installed. If Session Manager is not installed on your system, it may be some other addon. Disable them a few at a time until you zero in on the one causing a problem.
