Rated 4 out of 5 stars
Sadly BarTab stopped working for me. A great addon that I don't would like to miss.
I've tested it on FF4 Beta9 Portable, Version 2.1 b2 - 2.0, OS. Windows 7. All tabs load on start up after a few seconds. Only pinned Tabs will be unloaded.
Hope you can fix that in the future. Thank you.

Jep, A ug in 2.0. I had to deactivate BarTab from now because it causes various crashes and doubles a tab instead of unload.
Update: This bug seems to be fixed in the beta
