Firefox 4 is finally ready to download. As the download counter shows, I am not the only one that is interested.
I find it more convenient to install programs with apt-get. Here is how to do install the latest release of Firefox.
To install Firefox 4 via commandline, you should:
sudo add-apt-repository ppa:mozillateam/firefox-stable
sudo apt-get update
sudo apt-get upgrade
Have fun!
