Five weeks later, the developer wrote today a new blog post to inform the Linux community that he managed to also package the Firefox Nightly and Firefox Wayland builds as Flatpak packages for distribution on Fedora 25 and Ubuntu 16.10 (Yakkety Yak) operating systems, as well as other OSes that offer Flatpak support, of course. The developer warns those who want to use the Wayland build of Firefox Nightly that it’s very experimental and it could crash quite often. Also, you should know that you need to run the next-generation Wayland display server (not X11) on your GNU/Linux distribution before even attempting to install the Flatpak.
