> Ctrl-F4 close them. Press and hold Ctrl, then F4 them one at a time.

Ctrl-F4 shuts down entire browser, Ctrl-W closes each tab with a press of w. This is behavior in Ubuntu and it holds true for most application windows.

Alt-F4 closes the entire browser, and indeed Ctrl-F4 closes the current tab. (Just tried it out, I've always used Ctrl-W for that.)

My bad now I tried the Ctrl+F4 and yes it works exactly the way OP said. I assumed he was talking about Alt+F4 :)
