Install Firefox 4.0 in Ubuntu 10.10 via apt

The easiest way to install the latest version of Firefox in your Ubuntu is by launching the following command:

sudo add-apt-repository ppa:mozillateam/firefox-stable && sudo apt-get update && sudo apt-get install firefox

This will update your current version of Firefox to 4.0.

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!

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

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

Type in your password:

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

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

You should now see two new repositories on the Other Software tab (one for the Firefox .deb packages and the other one for the source packages). Click on the Close button to leave the Software Sources window:

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.

A computing power: Firefox 4.0 draws Ahead

After last week, the benchmarking project, I combed through comments and ran the numbers myself using latest Firefox 4.0 beta, Chrome 10 and 11 Opera. The results? It seems that Firefox 4.0 has the Crown of speed on Linux, for now.

If you look through the comments on draft weekend, you will see many results is standalone browsers or one or two browsers - interesting, but not of apples to apples comparisons because you cannot compare Opera 11 on a machine with Firefox 4.0 on another machine. But a few people who made the "work at home," did tally Firefox 4.0, Chrome 10 and 11 of the Opera. And I did so, taking a few hours Monday of this week to run each browser through the tests on a system running Linux Mint 10.

Here is the setup I used: Linux Mint 10 64-bit, Core i7 Q720 @ 1. 60 GHz and 8 GB of RAM. I tested Firefox 4.0b13, chromium 10.0.648.134 and Opera 11. Here are the results I received, with winners in bold:

SunSpider

Firefox 4.0B13: Ms. 296.3Chrome 10: and msOpera ms 11: 358.6

V8

Firefox 4.0b13: 3928chromium 10: 4637Opera 11: 3496

Kraken

Firefox 4.0B13: Ms. 6040.9Chrome 10: 14514.0 msOpera ms 11: 12244.5

Not surprisingly, chromium breaks out to come to landmark chromium team uses to test Chrome, and Firefox doing well come to reference using the Firefox team. (I do not say that the benchmarks are biased - I say that the teams are running various tests and things slightly different adjustment, which means that they perform better on the things that they test.)

To run the tests, I closed all other applications (not counting things like NetworkManager, course, or background applications as boy missed). Then I began each browser, ran each test three times and then left the browser. The scores listed are the best of the three. Also, I used the 4.0b13 Firefox Ubuntu APP rather than the 64-bit Mozilla version. I test that is using SunSpider and concluded that it was in the same district the 4.0b13 of Firefox provided by the app.

Bottom line? It seems that Firefox is just a little ahead cognacs. But really? There is not much daylight between the major browsers.

Thanks much to all the people who submitted "duties," too. It is interesting to see the scores for some of the browsers that I have not tested, such as Midori and Konqueror. Be sure to cream off through the comments and add your own results if you have time.

With three more Firefox releases planned for 2011, I will be keeping a close eye on the benchmarks and research of testing more on browsers that we use on Linux.
