Chromium
An open-source browser on which Google’s Chrome browser is based. Its relatively lightweight memory usage makes Chromium a good choice for the Pi.
To install open LX Terminal and type:
sudo apt-get install chromium-browser

chromium --kiosk --incognito http://google.com
To exit Kiosk mode: ATL+F4
Openening In App Mode
No toolbar, buttons etc
chromium --app=http://google.com
Opening Maximized
In theory the this special undocumented option should work:
-start-maximized
But in our tests using it on the command line and by adding it to the CHROMIUM_FLAGS by editing this file has no effect:
sudo nano /etc/chromium/default
