Firefox 2 feature: Recently Closed Tabs

We know (at least we are pretty sure) that one of Firefox's best features, confirmation before quitting with multiple tabs open, is coming to Safari 3 but the stealing shouldn't stop there (or is it borrowing when Apple does it?). The recently introduced version 2.0 of Firefox has a very nice little feature lurking in the 'History' menu. You'll notice a 'Recently Closed Tabs' option is now available. This lists tabs that you have recently closed (wacky, huh?).

Now, this might not seem mindblowing but if you are like me you often have many, many tabs open and every once in a great while you close the wrong one. Opening up that wrongly closed tab is now much simpler. Apple, are you paying attention?
