More useful than it might first appear! Rated 5 out of 5 stars

I put this one in my "Apollo! Pack" collection because it helps me tremendously. I am a power user and I am on endless pages every day. This quickly turns into a history of thousands of pages and an intolerable startup delay. This one helps after deleting the history to clean it back up and get it back down to normal. For those who think that Firefox is slow try deleting the history and running this and you will see a startup improvement.

This review is for a previous version of the add-on (0.40.1-signed.1-signed).
