I have been wanting to have the most up to date browsers for Linux Mint as its great to be able to see the cutting edge features before they are fully deployed.
This post shows how you can quickly setup Firefox Aurora and Chrome Dev builds on Linux Mint (will also work on Ubuntu as well).
Note : you cannot also run the Stable versions of Firefox & Chrome and the same time so they will be replaced.
First update the repository from Mozilla to Aurora :
$ sudo add-apt-repository ppa:ubuntu-mozilla-daily/firefox-aurora
Then update the repositories and install Firefox :
$ sudo apt-get update
$ sudo apt-get install firefox
Firefox and you will now have the Aurora version. The Sotware Manager
also recognized the change and updated to Aurora. All the bookmarks,
settings etc will be the same as the stable Firefox version.
Chrome Dev Channel
The slight difference with Chrome is that you need to remove the installed package. First go to the Chrome Release Channels and download the Dev Channel unstable build for you OS architecture.
Next remove the current Chrome stable build :
$ sudo dpkg -r google-chrome-stable
Install the downloaded build :
$ sudo dpkg -i google-chrome-unstable_current_amd64.deb
Startup Chrome and enjoy being on the Dev channel builds!
