Oh, Mac IE. You gave us such hope. You showed such promise. But like your Windows cousin, you languished for years as the competition raced past you, like some burned-out former child prodigy that never lived up to the promise of his formative years. Never growing out of those strange ticks and quirks that we all hoped you would.

On the bright side, now when you roll your eyes at someone and quip, Oh God, don’t use that browser, you have a succinct rationale that doesn’t involve all the muss and fuss of dragging out your well-worn Web Standards soapbox. Uhhh, like, they discontinued it, dude. Even the people who made it say you should use something else now.

Good night, sweet prince, and flights of Box Model Hacks sing thee to thy rest…

Internet Explorer for Mac

This is great news because, as it stands now, the tab UI in Firefox is fundamentally flawed. Well, the tab close button to be specific. In the current implementation (a single close button, positioned to the far right of all open tabs) there is little to no connection between the button and the specific tab on which it is going to perform its designated action. It’s subtle, but fatal. At first blush, one might even say it makes it look as though the purpose of the button is to close the entire tab bar (that is, all open tabs at once). This is one case where Safari gets it right. Each tab contains its own close button. The relationship is obvious, direct, and instantly recognizable.
