Unfortunately, the official Ubuntu archives don't have FireFox 3.5 yet. I just talked with asac in #ubuntu-mozillateam to get his and the team's recommendation. So, as of today the best way to get Jaunty FF 3.5 is to add a Personal Package Archive (PPA) as described in asac's blog post.
http://www.ubuntusolutions.org/2009/07/ubuntu-firefox-3-5-install-use-ubuntu-mozilla-security.html For command line folks, this means: sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 7EBC211F sudo sh -c "echo 'deb http://ppa.launchpad.net/ubuntu-mozilla-security/ppa/ubuntu jaunty main' >> /etc/apt/sources.list" sudo apt-get update sudo apt-get install firefox-3.5 firefox-3.5-gnome-support to set 3.5 as the system default: [1] cd /usr/bin sudo ln -sf firefox-3.5 firefox There are a couple other ways to get it as well. The daily build PPA has more cutting edge packages but is less stable. FF 3.5 is also available as a jaunty-proposed package but I don't recommend this way. Of course one can also get the software directly from www.getfirefox.com but you are on your own then. You won't be able to take advantage of the automatic updates, integration work and testing efforts that go into the packaged versions (and later security updates) that get delivered automatically. I hope this helps.
