using firefox 3.5.x in Linux ... Its not just that easy, apparently.

I got tired of looking for a repo version and decided to get the bin pkg from Mozilla.

Here’s a really quick way to get 3.5.2 running on your Ubuntu or RHEL/CentOS system.

I removed the Firefox 3.0 that shipped... In this case, with CentOS. This tutorial taken from some Ubuntu user's post/page...I forget.

Open up Terminal (Applications > Accessories > Terminal) and run the following commands:

1. cd /tmp
2. wget "http://download.mozilla.org/?product=firefox-3.5.2&os=linux&lang=en-US"
   Note: Your download link may be different depending on your country and language. I got the link by clicking the download link, canceling the automatic download, right-clicking the “Your download should automatically begin in a few seconds, but if not, click here” link, and selecting Copy Link Location.
3. tar xvjf firefox-*.bz2
4. sudo cp -r firefox /usr/lib/firefox-3.5.2
5. sudo mv /usr/bin/firefox /usr/bin/firefox.old
6. sudo ln -s /usr/lib/firefox-3.5.2/firefox /usr/bin/firefox-3.5.2
7. sudo ln -s /usr/bin/firefox-3.5.2 /usr/bin/firefox

Close Firefox and then reopen. You should now be running Firefox 3.5.2.

If for whatever reason you’d like to switch back to your previous version of Firefox, simply run the following commands from Terminal:

1. sudo mv /usr/bin/firefox /usr/bin/firefox.bak
2. sudo mv /usr/bin/firefox.old /usr/bin/firefox
