Huh, I never bothered to even check for that because I never assumed google would allow me to do that. How surprisingly nice of them (or whoever sued them like it was with MS windows). Thanks!

EDIT: Do you mean simply browser under default apps? That is already set to Firefox but that does not really change the browser that pops up inside apps.

EDIT2: Okay, I'm a moron. The browser that opens inside the apps is already Firefox, but some very light form of it since no addons or settings work there. I'm stuck with having to do 2 more clicks each time whenever I need a digital condom
