After less than a day, Firefox will slow to a crawl, repeatedly flashing "not responding" every second or so. Eventually, after minutes or hours, this addon will crash with a notification that it cannot write to its database. The only fix for this is to kill the Firefox process and start over. Then you're good for another few hours of activity before you do the same dance again. I'm going to try TabMix.
