wow...can't say I agree with this :-P Things like re-arranging menu's really don't seem like 'improvements', especially if it renders muscle memory useless. The new tabs are probably my least favorite change.<p>Though, oddly, like the author - containers/workspaces are what keep me on FF. I have multiple profiles setup, some with multiple containers. I'm loathe to go thru setting that up again on a different browser...
