Certainly isn't me. I'm still salty about Firefox 2 removing the "close current tab" button and putting an X on every tab instead. It was nice having that muscle memory instead of having to hunt down whichever tab you're currently focused on.

I've never used Firefox 1.x so haven't used that UI, but it sounds like something they could've made configurable but didn't want to, for whatever reason.

However, in all the tabbed browsers I've used, Ctrl+F4 closes the current tab.

Ctrl+W also does that, and is much easier on the fingers (unless your hands are huge).

Surely there's an extension for that?
