How do I install the latest stable version of Firefox?

1

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)

Go to Applications > Ubuntu Software Center.

Then go to Edit > Software Sources.

Click on the Other Software tab.

Click on the Add button and then type (copy/paste) the following line:

Click on Add Source (system will ask you to update your sources).

After the update, go to System > Administration and click on Update Manager to perform the upgrade. Firefox 4 will now be...

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 menu entry in Firefox is disabled or hidden in recent versions of Ubuntu. Ubuntu supported updates to Firefox are managed through the package-management system.

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:

Go to the ubuntu-mozilla-security personal package archive.

Want to try out the latest Firefox daily builds (the version is actually called "

Nightly

") from a PPA without affecting your current stable Firefox installation (or

Firefox beta

)?


The Mozilla Daily PPA now provides "Firefox Nightly" that doesn't mess with your current Firefox installation: the builds have been renamed to "firefox-trunk" so you can install Firefox Nightly side-by-side with any older Firefox version.

In my test, Firefox-trunk started with a new profile so my stable Firefox profile wasn't affected. However, after starting both Firefox stable and Firefox-trunk in the same time a few times, somehow Firefox-trunk started using my stable Firefox 4 profile so I recommend you don't use two different Firefox instances in the same time.

At the time I'm writing this post, adding the Mozilla Daily PPA will install Firefox 6.0, however Firefox 7 was recently uploaded to the PPA so an update should be available in a few hours (if...

Mozilla will enforce the signing of extensions in Firefox in Firefox 40. This particular version of Firefox is scheduled for release on August 11, 2015 to the stable channel.

Add-on signing refers to a new system implemented by Mozilla that requires extensions for Firefox to be signed by the organization in order to install them in stable and beta versions of the Firefox web browser.

Developers who want to make their extensions available to stable or beta users of Firefox need to get them signed through addons.mozilla.org (AMO) even if they plan to publish it only on third-party sites and not Mozilla's main add-ons repository.

All latest versions of extensions on Mozilla AMO are signed automatically. This means that Firefox users may run into issues when they try to install old versions of extensions hosted on AMO and extensions not hosted on the site or submitted to it for the signing process.

If that is the case, the following options are available to...

There could be several reasons why you want to stick with a specific (old) version of Firefox web browser, instead of updating it to the latest version. Some of your favorite add-ons could no longer work after Firefox update; you may want to try out an old Firefox extension which has not been updated for too long a time to be compatible with the latest Firefox; some web application's user interface may no longer be accessible after you have upgraded your Firefox, etc.

While it is recommended that for security reasons, you always stay up-to-date with the latest release of Firefox, you may still want to go back to an old version of Firefox if it is absolutely necessary. It is not very complicated to install an old version of Firefox on Linux. The following is 5-minute guide to do it.

First, download the version of Firefox that you want from Mozilla FTP archive.

In the above archive, there are two binaries available for each version. 32-bit Firefox binary is...

There are several methods of installing a non-default version of Firefox, that are covered by my tutorial Installing Other Versions, which has detailed explanations and method comparisons. So I will post here only the relevant information regarding Firefox 4. Please do not use multiple methods. Pick one and stick with it or revert the changes before trying a different one. I recommend the manual installation method, since depending on the PPA you choose, you will also update Firefox 3.6 and other Mozilla products.

Since it is still a Beta release and there are some radical changes in this version, is recommended that you install it side-by-side with the default version and use a different user profile, in order to avoid data loss.

Method #1 - Manual Download & Installation

First you need to download it form Mozilla [pick one only]:

The easiest way to install Firefox 4 downloaded from Mozilla is to use my extension FoxTester. It allows you to install any...

I had the exact same problem, and had come to the conclusion that Chromium had been abandoned. In any case, when the Unity Webapps Preview was released I installed it right away, and it updated both FireFox and Chromium. After FireFox moving so slowly it hurt, I moved back to Chromium and decided I could live with it being outdated... Lo and behold! It had been updated!

To install the Webapps Preview:

sudo add-apt-repository ppa:webapps/preview sudo apt-get update sudo apt-get install unity-webapps-preview

Wait for everything to install, and Chromium should be fully updated:

If you don't want to use the Webapps, then you can just go to Chromium's extension page and select to disable the add-on:


If you want to uninstall Webapps:

sudo apt-get install ppa-purge sudo ppa-purge ppa:webapps/preview


N.B. Using ppa-purge removes all the packages that were installed or upgraded by the ppa you added: this means that Chromium and FireFox (as...

Firefox users who prefer a 64-bit version of the web browser instead of a 32-bit version on Windows will be able to install and use a 64-bit stable channel version when Firefox 41 gets released.

Firefox 41, which will be released on September 22, 2015 if things go as planned, will be offered as a 32-bit and 64-bit version for the Windows platform.

All other channels of the browser, that is Beta, Developer and Nightly, are already provided as a 64-bit version, and that is also the case for the Linux and Mac OS X versions of the browser.

So why is the release, originally planned for Firefox 39 and then 40, delayed again? According to Mozilla, it is because of other improvements and changes launching in Firefox 41.

The organization mentioned sandboxing and NPAPI whitelisting in particular which it aims to deploy with Firefox 41.

One difference between 32-bit and 64-bit versions of Firefox for Windows is that the latter will restrict plugin access...

I'll second the discussion above but flush it out a bit. I learned something, that even-number.04 are LTS versions and the first time I heard it stated like that.

If you don't like messing and re-installing every 6 months the most recent LTS version is definitely the best option. They are updated for 2 years and you don't have to touch them for 2 years. At this moment it is 14.04. If they work, then why mess with it. This is what I do for my print server EeePC as well as my for my wife's Asus netbook. My wife doesn't want want any hassle and does not push the envelope in any kind of way. She just wants to turn it on and use Firefox, LibreOffice, and watch media.

On the other hand, your hardware may push your choice. I just bought a new Lenovo Yoga Pro 2. 14.04 had several bugs for this hardware (e.g wifi didn't work) because it is so new. These bugs were fixed with the next kernel release that came with 14.10 distro. Even if this was my wife's computer, 14.10 was...
