How to Install Firefox 9.0 in Ubuntu 10.10 and 10.04?

Few hours ago Mozilla released the latest version of the Firefox Web browser 9.0. As with previous releases, this version too includes few improvements (both performance/speed and enhanced security, etc) and bug fixes as usual.

Simultaneous to this, they’ve also released a totally re-designed version for the Android platform. And although I don’t care that much since I don’t use Mac OSX but if you do, then according to Mozilla now Firefox supports “two finger swipe” too.

Some of the other main features to mention…

*. Improved Java-Script engine. If you care about the numbers, then they say that it’s around 30% or more faster this time when comparing with previous releases.

*. HTML5, MathML and CSS improvements.

Firefox-logo *. And now users can know whether “Do-not-Track” feature is enabled/disabled via a Java-Script.

*. Few new icon mouse hoover effects which looks cool.


*. Over 1000 of bug fixes.

The most significant change in this version of Firefox is obviously the Java-script engine’s performance which can result in a performance increase of 50% or more but it only applies while loading some web sites.

If you use Ubuntu 11.10 Oneiric Ocelot or 11.04 Natty Narwhal then they haven’t come up with the updates officially yet. But if you just can’t wait then you can try install Firefox 9.0 using the Mozilla Security repository (which includes packages that are waiting for their final testings and approval for official releases).

For that you can use the below commands in your Terminal window.

sudo add-apt-repository ppa:ubuntu-mozilla-security/ppa

sudo apt-get update

sudo apt-get install firefox

But remember, these packages are still not released officially and in their “testing” periods thus you’d better off waiting for the official release :).

Quite ironically though, both the somewhat “old” Ubuntu 10.10 Maverick Meerkat and 10.04 Lucid Lynx users can install Firefox 9.0 already thanks to the Mozilla PPA officially! (well I guess Ubuntu is just giving a bit of an extra care for their recent releases here).

As usual, for that, open your Terminal window and enter the below commands.

sudo add-apt-repository ppa:mozillateam/firefox-stable

sudo apt-get update

sudo apt-get install firefox

Yep that should do it.
