Firefox 66 Is Now Available for Ubuntu 18.10, 18.04 LTS, and 16.04 LTS Users

Released earlier this week, the Mozilla Firefox 66 web browser has landed in Ubuntu’s repositories with a bunch of great improvements, such as the hidden system title bar that respects the GNOME guidelines. Not only Firefox will now look good, but you won’t have two title bars, nor you’ll have to use extensions to get rid of one. Apart from the looks for GNOME users, which is now the default desktop environment on Ubuntu 18.10 (Cosmic Cuttlefish), Mozilla Firefox 66 comes with various under the hood improvements, such as freezeless downloading of files and faster web content loading by reducing the crash rates and increasing the processes from 4 to 8.
