I'm not sure how I feel about the changes to the tab UI in Firefox 2. On one hand, the fact that you no longer have to go all the way to the far side of the window to close a tab is nice. Or, it would be nice if I hadn't trained myself to go to the far side of the window to close a tab. On the other hand, I'm really not sure how I feel about having tabs off screen and having to use the drop down menu or arrow button to move over to where you can see them. In concept, I can see how not having the tabs get really really small when you have a lot would be a good thing, but I'm still having trouble getting used to it.
