Organizes Firefox nicely, recent performance bug Rated 5 out of 5 stars

I gave this add-on a 5 star rating for the years of usefulness it has provided - having a single location to manage all of my bookmarks, add-ons, history, downloads, etc. has been a great way to keep Firefox organized.

However, something has happened in the past month and this add-on is now causing horrendous slowdowns in the browser - even if it is the only add-on enabled. I had no choice but to disable this add-on, else pull my hair out waiting for many seconds at a time for mouse clicks to be accepted, individual keystrokes to be recognized, etc. Hope the developer can figure out what's going on soon, because Firefox feels all wild and wooly without it.

This review is for a previous version of the add-on (0.7.15).  This user has a previous review of this add-on.
