Yup, it's just like the early 2000s all over again. Except this time it's much more clunky to explain, since the complaints by Firefox (Mozilla) and Chrome (Google) refer to a specific mobile ("Windows on ARM") version of Windows 8, and it has to do with the fact that on IE will be allowed to run in one particular "mode" of the operating system (Windows 8 has two modes...it's... complicated...)
