I’m tired of having my browser hijacked by window.alert(). Before the advent of tabbed browsing, I’m sure that taking over the application wasn’t that bad, but now that I have multiple web pages and applications open in different tabs it’s a different situation. I don’t see why my browser won’t let me do anything (I can’t even close it!) when some website wants to tell me something.

Is this feature listed for FF3? If not, it should be. Or maybe an extension could take care of this? Any takers?
