While Chrome is a reasonably good browser (and it’s in the name of the ChromeBook so we can expect it to be pretty well integrated), and the version on the ChromeBook seems well enough suited to the laptop I’ve bought, being free of Google and on a full featured Linux browser seemed one of the first things I’d like to achieve.
While I initially thought of Opera, after battling with a seeming incompatibility with the Linux version provided for the ChromeBook I decided to see if Firefox would be easier. While there is no firefox package a quick Google discovered thet firefox-esr is the standard I should install and
# sudo aptitude install firefox-esr
(using the aptitude manager installed via: # sudo apt-get install aptitude )
and I was able to launch firefox from the command line ( # firefox & ) and see it in my ChromeBook launcher!
