HowTo: Install Latest Version of Firefox on Ubuntu


Want to install the latest version of Firefox on Ubuntu but don’t know how? Don’t worry, I’m here to help you.

For software compatibility reasons, Ubuntu doesn’t immediately include newly released programs to the Software Center. That’s why you don’t automatically get Firefox 4 but instead see that the latest up-to-date version on your system is Firefox 3.6+. If you don’t want to wait, you can install the latest version manually and I’ll show you how to do it in two different ways.

Installing Firefox on Ubuntu via GUI (graphic user interface)

  1. Go to Applications > Ubuntu Software Center.
  2. Ubuntu Software Center

  3. Then go to Edit > Software Sources.
  4. Ubuntu Software Center

  5. Click on the Other Software tab.
  6. Ubuntu Software Center

  7. Click on the Add button and then type (copy/paste) the following line:
  8. Ubuntu Software Center

  9. Click on Add Source (system will ask you to update your sources).
  10. Ubuntu Software Center

  11. After the update, go to System > Administration and click on Update Manager to perform the upgrade.
  12. Firefox 4 will now be available on the list. Click on Update and it will be installed on your system.

Installing via Terminal (command line)

  1. Go to Applications > Terminal or Applications > Accessories > Terminal.
  2. Ubuntu Terminal

  3. Type (copy/paste) in the following commands one at a time:
  4. Close the terminal.
  5. Firefox 4 is now installed on your system.

For those of you who want to install Firefox 4 but want to keep Firefox 3.6 or other older versions, here’s what you can do:

  1. Download Firefox 4 from the Mozilla Firefox page (make sure the file you download is in TAR.BZ2 format)
  2. Create a new folder for Firefox 4.
  3. Unpack/unzip the BZ2 file to that new folder and run (double click) the executable text file.
  4. Installation will proceed and just follow prompts.

Btw, these methods are not limited to Firefox 4 but will work for the latest stable version that Mozilla releases. Hope this short and simple guide helped you install Mozilla Firefox on Ubuntu.

    Really helpful tutorial here Jaypee. I’m actually more used to installing software and repositories via the Terminal instead of the GUI.
