I am new to Ubuntu. I have a Live USB running 12.04 LTS. I also still have Firefox version 12.0+build1-0ubuntu0.12.04.1 installed and want to upgrade to version 19.
I have searched a bit and my understanding is that Firefox updates are now part of the main system updates. When I run Update Manager I am told that everything is up to date.
I tried running Synaptic to see if is would see a newer version of Firefox and it does not provide an update option for Firefox.
I am thinking that I might be able to uninstall and reinstall Firefox but much rather get the update working.
