I can't decide which way I like the tabs though - with one close button on the far right (ie FF 1) or close buttons on each tab (ie FF 2). Since I've got 1 at home and 2 at work, I've been known to try to click the wrong place

I'm trying to see if I can get used to having it on each tab, but it's annoying me so far.
Luckily, you can change the behavior in about:config
browser.tabs.closeButtons 0 = close button on active tab
browser.tabs.closeButtons 1 = default, close button on all tabs
browser.tabs.closeButtons 2 = no close buttons
browser.tabs.closeButtons 3 = Fx 1.x style, one close button on right
update: right after posting this, I accidentally deleted a tab while trying to switch to it. So I quickly changed the value to 3.

update #2: just learned something useful. If you accidentally close a tab, CTRL-Shift-t will bring it back.
