Most of us by now have heard of Google's Chrome web browser. The Chrome browser is based on an open source project called Chromium. There's not really much difference between the two. Chromium is basically just Chrome without the Google branding and without the extensive EULA.
You can install the Chromium browser from the PPA for Ubuntu Chromium.
First you'll need to add this particular PPA to your Apt repositories. Open a terminal and enter the command:
sudo add-apt-repository ppa:chromium-daily/beta
Update the apt package list with:
sudo apt-get update
And finally, install Chromium with:
sudo apt-get install chromium-browser chromium-codecs-ffmpeg
