Take a look at this chart and see which Swiftfox version is best suited for your computer based on your processor.
Install Swiftfox in Ubuntu / Debian?
Ubuntu (and all Debian based distribution) users will be pleased to know that it even comes with a repository which you can add by issuing the following command in a terminal:
sudo sh -c “echo ‘deb http://getswiftfox.com/builds/debian unstable non-free’ >> /etc/apt/sources.list”
and then, to install Swiftfox:
apt-get update
apt-get install swiftfox-xxxxxxx
I for instance, have an Intel Core 2 Duo processor, so I have to install the Prescott version:
apt-get update && apt-get install swiftfox-prescott
Install Swiftfox on other Linux distributions?
If you don’t use Ubuntu, the best way to install Swiftfox is to download and run the installer. Everything should work (Flash, etc) right out of the box, and your Firefox profile will be used:
sh install-swiftfox.sh
Swiftox is just an optimized build of Firefox so yeah, every add-on or theme that works with Firefox will also work with Swiftfox. Furthermore, Swiftfox will use your Firefox profile so all your Firefox settings will be kept while using Swiftfox.
