IE Tab: Never Launch the Internet Explorer Browser Again!
It sounds crazy, but there are some sites on the Internet that still don’t play nicely with Firefox (ahem, MTV2). Why?!
But instead of launching Internet Explorer on top of your favorite browser, get the Firefox add-on IE Tab. It will embed the IE engine within Firefox.
So if you’re visiting a website with videos that just won’t load with Firefox, right-click and switch rendering engine. It will reload everything IE-style.
