Install Firefox 3.5 in Ubuntu 9.04

Ubuntu 9.04 comes pre-installed with Firefox 3.0.x. This was the current version of the browser at the time the Ubuntu version was released.I have recently discovered that there is a package available for Firefox 3.5.x in the universe repository, which will install the latest version of the browser alongside the default version. I know how important web browsing is for most of us, and having the latest browser with the latest features is a requirement.

Install the package

To install the package you’ll need to make sure you have the universe repository configured. This should be enabled by default, so unless you’ve manually removed it you should be fine. Once this is verified you can install the package using the command below (or click the link):

[email protected]:~$sudo aptitude install firefox-3.5

Once this package is installed you should have a new menu entry in Applications > Internet called “Shiretoko Web Browser”. This is named after the development codename (I believe) of the 3.5 branch.

Required tweak : User-Agent

I’m unsure the reasoning behind it (probably the Mozilla license issue regarding redistribution using the name & logo), this version of the browser identifies itself with its development codename and not the known “Firefox” name. This will break functionality on a number of sites that verify the user-agent string. There is a simple way to fix this, which I’ll outline below.

In your address bar, enter the url: about:config

Accept the notice that tinkering with the settings in this section might catastrophically break things, destroying the world and all mankind.

In the field at the top, enter the string: general.useragent.extra.firefox

Double-click on the result and change the string from “Shiretoko/3.5.2″ to “Firefox”.
