How to upgrade Firefox 4 manually in Debian?

[pLEaSInG]

I am using Linux Mint Debian Edition in my system. I was using the older version of the firefox in my desktop. I have seen that there is a latest version of the Firefox available in the market, I want to get the new version. The issue I am seeing is that it probably will not show up in the package manger from a long time. So I thought of manually installing it. So I have downloaded the file and untared the zip file. So I manually copy the files over my old firefox directory, but that dint work. But only the older version of firefox is getting loaded. I really don’t know how to link it. Can anyone help me?

The simple way to get is, go to the system and then to the administration and the click on the Update Manager. You can see that there is an Other Updates option you can see in the Update Manager. In Other updates there will be an updates available for mozilla. Checks mark all the options for the mozilla and click on check. After that it will prompt you to enter the password to get it authenticate. After you click on the Authenticate, then you firefox will download the updates. After the updates are downloaded, you can run your firefox. There might be some updates that are not compatible with your add-ons. After the compatible updates are downloaded click on the Finish button. After that, restart your firefox.

Mozilla Firefox was rebranded by the Debian Linux and was named Iceweasel for Mozilla Firefox. It is the same as the Mozilla Firefox program. You can install it using the aptitude command or by the apt-get line option.
You need to get the following line added in the /etc/apt/sources.list
1. Just enter the code:

# echo 'deb http://mozilla.debian.net/ squeeze-backports iceweasel-4.0’

2. To get it install type the following command:

# apt-get install -t squeeze-backports iceweasel

3. After you get it installed, enter the line to start it:

$ /usr/bin/firefox

4. Or you can also run it by:

$ /usr/bin/iceweasel

I was having Firefox 3.6 installed in my Debian Squeeze, I was not happy with it. There is a free clone available for the Firefox known as Iceweasel. You can install the iceweasel 4 in your Debian by following the below steps:
For apt you need to create the .list file:

cat > /etc/apt/sources.list.d/iceweasel.list << "EOF"
deb http://mozilla.debian.net/ squeeze-backports iceweasel-4.0
EOF

After that add the gpg file for mozilla.debian.net:

wget -O- -q http://mozilla.debian.net/archive.asc | gpg --import

After that allow the key:

gpg --export -a 06C4AE2A | sudo apt-key add -

After you get the key, update your system:

apt-get update && apt-get dist-upgrade -y && apt-get install iceweasel -y
