Rated 5 out of 5 stars

I have been using this for over two weeks now. And as someone who makes heavy use of tabs, I find this to have reduced my FF memory consumption by around 80%!

The only additional setting that pushed this down further to around 85% is this setting - "When I don't visit a tab for a while" = "Unload it after" .. "20 minutes".

It is now a part of my permanent add-ons collection (the only other two are Adblockplus and XMarks).

Thank you!
