Seems like how Firefox 7 beta manages memory broke this add-on.This review is for a previous version of the add-on (1.4.1-signed).

This is great!
I suggest having two memory settings. One is warning with yellow icon that warn user to manually restart. And another setting for dangerous red that can't wait for user and automatically restart.
