Oh, like there aren't any of those for IE. Seriously though, yes I like Firefox, but it isn't the be-all-end-all of browsers, there are others that are pretty good too. IE just happens to be one of the crappier ones out there.
I spent a fair bit of Friday fixing a problem that only occurred in IE, due to a combination of some strange Javascript timing issues in IE, and the very stupid "useability feature" that IE has where pressing the Enter key in a form submits it... BEFORE processing any other form events. Very very bloody annoying. Had to write a key handler to catch Enter key events and return false, and put in an onKeyDown event on the fields to flag them as changed, and make IE pause for half a second before submitting the form to make sure that everything else finished happening. Went from like 15 lines of code to more like 50 (after optimisation), all because IE has to be bloody difficult.
Stupid browser.
Yay, after showing my workmates what Firefox can do, I now have at least 6 more converts, and all of them have seen the light and now hate IE too :D
