Such a shame they're having to do this. Being in the browser is such an awesome thing for so many people, it makes it so accessible and all because Firefox and Chrome want to lock down their systems, Quake's having to go back to a standard program.
Shame. And shame on Mozilla and Google, no longer pioneers in their own fields it seems - it was only months ago we were being shown the Unreal Engine running in a browser, now hopes of anything really materialising have vanished.
