Firefox History Cleanup

Firefox, originally uploaded by Xurble.

So far I'm liking Firefox 3.

I'm even getting used to the smart address bar thingemy.

But since it's so damn smart now, it feels like a missed opportunity to fix one of my biggest browser auto-complete bugbears.

How do you get rid of an erroneous (say mistyped) entry from the list? Particularly one the goes to the top of the list and obscures the thing you're really after.

I reckon a delete from history button (X marks the spot) in the drop list would do the trick.
