Install Firefox 13 in Linux: I installed in Debian squeeze

Debian Iceweasel is not Firefox, even if it is derived from Firefox, sadly. Once I updated the default flash player to Adobe flash player, Iceweasel crashed more often than not.

So, the best option was for me to install Firefox and what's better than the latest version! I got considerable help from this site. Essentially the instructions are simple:

1. Download Firefox from Mozilla channels www.mozilla.com/firefox/channels/

2. Store it in the Downloads directory. Exit Firefox.

In case of Debian, uninstall Iceweasel by
#apt-get remove iceweasel

3. Move to the directory and extract the contents
#cd ~/Downloads/
#tar xjf firefox-13.0.tar.bz2

4. Go to your /opt directory, in case /opt/firefox already exists, remove it by
#rm -r /opt/firefox
Use 'sudo' for Mint or Ubuntu. In case of Debian squeeze, execute all the commands from  Root Terminal.

5. Move the extracted firefox to /opt
#sudo mv firefox /opt

6. Create a symbolic link of the new Firefox by
#ln -s /opt/firefox/firefox /usr/bin/firefox
Use 'sudo' for Mint or Ubuntu. In case of Debian squeeze, execute all the commands from  Root Terminal.

Now once you start Firefox, the previous icons will be updated and you'll have the brand new version of Firefox.

In my case, I added Linux mint debian repository and downloaded Firefox but it was in Dutch! I uninstalled for Firefox (Dutch) and Iceweasel and hence, couldn't find any /opt/firefox directory. To install Firefox 13, I reinstalled Dutch Firefox and proceeded with these steps.
