Introduction

When a new version of Firefox comes out, there is some delay until it can be downloaded and run. This page will explain how to install Firefox as soon as possible. The Check For Updates link in Firefox is disabled in Ubuntu. Firefox should only be updated through the package-management system.

Instructions for the impatient

Low difficulty, high safety: these packages are maintained and fully tested by the Ubuntu Project

  • Hardy - Karmic: Coming Soon
IconsPage?action=AttachFile&do=get&target=IconWarning3.png This section explains how to install packages that have not been fully tested. If you encounter bugs, please file against the firefox package and tag PPA.

Firefox-stable channel

Medium difficulty, medium safety: Firefox 3.6 completely replaces previous versions of Firefox and incompatibilities may arise. Mozilla team made Firefox 3.6 available to Ubuntu community for testing.

  1. Go to the mozilla-team firefox-stable personal package archive.
  2. Karmic 9.10 or later: Add ppa:mozillateam/firefox-stable to your system's Software Sources.
  3. Jaunty 9.04 or earlier: Follow the official instructions on how to use software from a PPA.
  4. Install the package for the new version of Firefox (e.g. package name is firefox)
  5. Report|any bugs that you experience - especially anything that previously worked, then stops working

Installing versions of Firefox in testing

Security-testing packages

Medium difficulty, medium safety: security-testing packages are halfway through the quality-assurance process. Although bugs are rare, no guarantees are given. Users of the most recent Ubuntu release can get new versions of Firefox a few days early from the semi-official ubuntu-mozilla-security archive. This archive holds updates to the Mozilla suite (including Firefox) while they're tested for security and stability. To get packages that have not yet been tested for security:

  1. Go to the ubuntu-mozilla-security personal package archive.
  2. Karmic 9.10 or later: Add ppa:ubuntu-mozilla-security/ppa to your system's Software Sources.
  3. Jaunty 9.04 or earlier: Follow the official instructions on how to use software from a PPA.
  4. Install the package for the new version of Firefox (e.g. this was firefox-3.5 when Firefox 3.5 was being released)
  5. A package without security testing will be made available a few days before general release
  6. Report|any bugs that you experience - especially anything that previously worked, then stops working

Daily updates

Medium difficulty, low safety: daily packages have not undergone any quality assurance. Daily packages are sometimes very safe, and sometimes don't work at all. Users of recent Ubuntu releases can get the latest development version of Firefox from the semi-official ubuntu-mozilla-daily archive. This archive holds updates to the Mozilla suite (including Firefox) that are under active development - for example, preview versions of Firefox 3.6.2pre and 3.7a1, were available at the time of writing. Although these packages will work well most of the time, you should expect crashes and other problems. To get packages that are only half-finished:

  1. Go to the ubuntu-mozilla-daily personal package archive.
  2. Karmic 9.10 or later: Add ppa:ubuntu-mozilla-daily/ppa to your system's Software Sources.
  3. Jaunty 9.04 or earlier: Follow the official instructions on how to use software from a PPA.
  4. Install the package for the new version of Firefox (e.g. this was firefox-3.6 when Firefox 3.6 was being released)
  5. A snapshot of a recent development version will be available immediately
  6. Report|any bugs that you experience
  7. To stop the ubuntu-mozilla-daily PPA riding roughshod over the Official Repositories consider Pinning.

As these packages install in their own directories and each use separate profiles, you can use 3.6/3.7 side by side. The new Firefox 3.6 will be found under the name "Namoroka Web Browser" and 3.7 under "Minefield 3.7 Web Browser" in Applications > Internet. This allows them to be distinguishable on the desktop and removes the need to alter any existing links.

Installing from the Mozilla website

Medium difficulty, medium safety: Sharing the same Firefox profile between different versions of Firefox (e.g., 3.0 and 3.5) may cause problems. As long as you avoid sharing a profile between versions (something which applies to all of the above methods, as well), Mozilla builds are safe to use, since they have undergone extensive QA prior to release. Please wait until the Ubuntu Mozilla Team make a stable version of Firefox available for your release. If you can't wait and want to use a Mozilla build of Firefox, see the guide for installing Mozilla builds.
