Rated 5 out of 5 stars

It seems not to work with FF 20. But look at the developer site and download the latest version there. This works for me.

This add-on is simply great. Because of it it is impossible for me to move to a different browser.

Moving tabs does not work anymore in FF 8. Will not upgrade to FF 8 as long as this is not fixed.

I found the reason for the big slowdown in FF4. It is the usage of the new HW acceleration. Switched this GPU usage off and as fast as before. And not only this add-on. Could be because I do not have a high end graphik card. Happy again with this add-on!

Much slower in FF4 than in FF3 Rated 3 out of 5 stars

It is a great add-on. But when I call up Firefox with many tabs it takes endless in FF4 until the tree is complete. In FF3 this was very fast. For this reason only 3 stars now
