works with mixed results. Though grouping seems to work ok but one of the problems I encounter is that tabs or tab groups/sorting get scrambled between restarts or crash recovery, even using things like session manager. Overrides manual moves of tabs also.

Even when turning off all sorting and grouping, behaviour is not very predicable causing grouping or sorting to appear to still be doing something.

Also conflicts with behaviour of other extensions that control opening of new tabs next to current (before or after).

Needs a blended solution of some kind. Otherwise I found it more annoying than useful. The only solution is to disable the extension.

Somewhat of a good idea but needs to mature to make it more predictable and behave better with other tab related extensions

BTW, I am using FF 3.5.9 & Mac OS X 10.4.11
