Tracker for work to be done to improve tabbrowser performance for both common user actions and traditional metrics.
URL of the list is http://wiki.mozilla.org/User:Rflint/Performance:Tabbrowser (I found it confusing)
We need to do this for b2 since I expect it'll screw with extensions among other things.
Ping on this - any progress here?
Why is a meta bug blocking-firefox3+?
The largest and most breakage-prone parts of this are mostly in on Linux and Windows - Mac will follow soon and I'll be filing some more dependancies for targets I've found with dtrace.
Flipping blocking-fx3 -- the only remaining bug here is not blocking 1.9/blocking fx3.
Gavin, is this bug finished?
