Installing Firefox 4.0 (.deb Package) On Ubuntu 10.10


In this short guide I will show you how you can install the new Mozilla Firefox 4.0 browser (released March 22, 2011) on an Ubuntu 10.10 desktop. Fortunately, there’s a Launchpad PPA repository that has Firefox 4.0 .deb packages, so we can easily install it through Ubuntu’s package manager.

I do not issue any guarantee that this will work for you!

 

1 Adding The Firefox 4.0 PPA Repository To Our Software Sources

Open the Ubuntu Software Center (Applications > Ubuntu Software Center):

1

In the Ubuntu Software Center, go to Edit > Software Sources…:

2

Type in your password:

3

In the Software Sources window, go to the Other Software tab and click on the Add… button:

4

You are prompted to fill in the APT line of the Firefox 4.0 repository – enter the following line and click on the Add Source button:

ppa:mozillateam/firefox-stable

Back in the Ubuntu Software Center, you should see that Ubuntu package database is being updated (it says In Progress in the left column).

Close the Ubuntu Software Center afterwards.

2 Installing Firefox 4.0

Now open the Update Manager (System > Administration > Update Manager):

In the Update Manager, there should be updates listed for Firefox (under Other updates (LP-PPA-mozillateam-firefox-stable)). Check them all and click on Install Updates:

Type in your password:

Afterwards, the Firefox updates are being downloaded and installed:

3 Launching Firefox 4.0

Now start Firefox.

When Firefox 4.0 is started for the first time, it will check if the currently installed Firefox add-ons are compatible. If incompatible add-ons are found, you can check for updates by clicking on the Check Now button:

However, it is possible that no compatible updates are found for your add-ons – in this case Firefox 4.0 will check periodically and inform you when compatible updates are available. Click on Finish to finally start Firefox 4.0:

This is how Firefox 4.0 looks:

To check if this really is Firefox 4.0, go to Help > About Firefox:

As you see, this is version 4.0:

  • Mozilla Firefox: http://www.mozilla.com/en-US/firefox/new/
  • Firefox Stable Channel Packages: https://launchpad.net/~mozillateam/+archive/firefox-stable
  • Ubuntu: http://www.ubuntu.com/
