Rated 4 out of 5 stars
I've always had a serious tab addiction, and wrote the Tabhunter addon to help deal with it. I finally installed BarTab, and it's reduced my FF memory load by about 75%.
The only problem is that I can no longer use Tabhunter to search the text of a page unless it's loaded. Which is what I was expecting.... Otherwise the two addons work fine together.
