I have Ubuntu 14.04

I was on firefox 39 and wanted the latest 53. I uninstalled 39 and tried to install the latest from tarball download.

I couldn't be bothered with all the simlinks and terminal stuff so I looked to reinstall from the repository but it only gave me firefox 28.

Why only firefox 28?
What's the most up-to-date firefox I can install from repository?

    The current one from the repository for me on 14.04 is 53.0.2... are you running sudo apt-get update before you try to install? (or since you've already installed the package now, sudo apt-get update && sudo apt-get upgrade)?

    Could you please edit your question to include the full, verbatim output of sudo apt-get update && sudo apt-get upgrade -f? Thanks. May 22, 2017 at 12:09
  • @DavidFoerster could you please explain -f? I looked at help.ubuntu.com/community/AptGet/Howto and only saw apt-get -f install. Even man apt-get limits -f to "This option, when used with install/remove"

  • manpages.ubuntu.com/manpages/trusty/en/man1/firefox.1.html shows firefox_28.0+build2-0ubuntu2_i386 so I'm assuming that that is the version 14.04 initially offered. In a properly functioning system, you should have the latest, which is v53, as others have pointed out.

  • @DKBose: I added -f in case there's a package management issue that blocks all package upgrades. Your quote doesn't restricts it to the "install" and "remove" commands; it describes a special behaviour for these commands. May 22, 2017 at 17:03

According to Launchpad v28.0+build2-0ubuntu2 is still the default Firefox version in Trusty if you don't enable security updates. Please enable security updates (see below)!

  1. Open System Settings > Software & Updates or run software-properties-gtk and go to the tab labelled Updates.

  2. Enable the checkbox in front of Important security updates (trusty-security):

    software properties > updates

  3. A dialogue will ask you to enter your password to confirm this action because it requires super-user privileges.

  4. Open Update Manager or run update-manager. This should update the package repository information and subsequently prompt you to install available package upgrades. There's also a list of available upgrades and the most recent Firefox version should be among them.

    The picture is of an old version but the layout should be almost identical
