Yes. Modded firefox, accompanied by an Invader Zim wallpaper (specifically GIR, that cute little non-sequitur machine....I LIKE DOOKIE!) I've finally been able to watch said series, and yes I do agree now that they shouldn't have prematurely canned it. They seriously should have let it have its planned grand finale.
Anyway, if there's enough demand, I'll tell you how I assembled that Firefox scheme. It's not a funky new version, it actually is the current version.
