Iceweasel is Firefox, only with different name and logo. It looks and performs exactly like Firefox, Firefox extensions/add-ons are 100% compatible and thus can be installed and used in Iceweasel.
But for many people, using the rebranded browser of Firefox somehow doesn't give a "real" Firefox eperience. And also, although in very rare cases, some websites reportedly can't recognize Iceweasel as Firefox, so the site can't be used smoothly on it. Another reason why some people prefer the real Firefox instead of Iceweasel, is because Iceweasel in Debian is a bit outdated, not updated to the latest Firefox (as of this writing, Iceweasel version in Debian Wheezy is Iceweasel ESR 10.0.7, while the latest Mozilla Firefox is Firefox 15.0).
For whatever reason, if you want to install the real Firefox in Debian OS, here I will show a little step-by-step tutorial/guide.
Debian doesn't provide Firefox in its official repository, so we need to install it in another way. In this method, I will show you a manual installation: how to install the real Mozilla Firefox web browser in Debian OS.
