Running Firefox instead of Iceweasel package?

[Erin Brinkley <erinbrinkley@ymail.com>]

I use the 'iceweasel' package for my main browser. But I was thinking about how Firefox itself (at mozilla.com) is much newer. I read a blog comment that someone started running the newest binary directly from Firefox instead of the iceweasel package. Is this even possible?? If so I'd like to try it, but don't want to break anything. Is it as easy as just downloading the Linux package from mozilla.com and installing it in /usr/local??

Thanks, Erin
