[UPDATED] HowTo: Install Firefox 3 in Debian

First upgrade your libgtk library to 2.10 above easily via adept or synaptic.

[FINAL UPDATE-BEST METHOD] June 30, 2008.

To install Firefox 3 on Debian do this:

$ wget ftp://releases.mozilla.org/pub/mozilla.org/firefox/releases/3.0/linux-i686/en-US/firefox-3.0.tar.bz2

$ cd /usr/local

$ sudo tar -xvjf /home/yourusername/downloadfolder/firefox-3.0.tar.bz2

$ sudo ln -s /usr/local/firefox/firefox /usr/local/bin/firefox3

*note that in the line /usr/loca/bin/firefox3 you can change 'firefox3' to a shorter and more convenient name like ff3, just replace 'firefox3' with the shortcut that you would like

*To run Firefox 3 just execute the command for it. For example

$ ff3

[OLD UPDATE] May 15, 2008. I didn't realize that you could just download firefox-linux here.

And then Untar the tar file, for example:

$ tar -xjvf firefox-3.0b5.tar.bz2

A new directory "firefox" would be created

$ cd firefox

$ ./firefox

The only downside to this method is you have to cd to the directory where you extracted firefox all the time. Works for me though.
