Firefox has been upgraded to version 63 across all platforms, including Linux, Windows, Mac OS, Android, and iOS.  The new version is focused on improved privacy protection by increased tracking protection to block third-party cookies.

With this feature, you can block cookies and storage access from third-party trackers:

New Features in Firefox 63

  • Enhanced tracking protection from the third-party cookies

  • Performance and visual improvements for Windows and macOS users

How to upgrade or install Firefox 63 in Linux

You can install the latest available version from the Software Center. Since Firefox 63 is just released, it may take a week or two to become available from the Ubuntu and other Linux repositories. This is the best and safe method of upgrading or installing Firefox.

If you can’t wait for the Firefox 63 to propagate through the repository sources, you can still try it from the tarball.

Download Firefox 63.0

Step 1) “Extract” the content. Example: firefox-63.0.tar.bz2 => extracted to firefox-63.0 directory.

Step 2) Launch ‘Terminal.’

Step 3) Use ‘cd’ command to navigate into the “Downloads” folder. I’m assuming that Firefox is downloaded to the “Downloads” folder.

cd Downloads

Step 4) Use ‘ls’ command to list the content of the “Downloads” folder. Next, use cd again to go into the downloaded binary package directory.

Step 5) The first step is to give bin file executable permissions. Enter “sudo chmod +x ./firefox-bin” command. Press enter.

Step 6) Type the administrator password when prompted and then press Enter.

Step 6) Finally execute the binary:


Firefox 63 should launch. That’s it!
