What's the best way to install Firefox Nightly and Developer Edition?

Greetings,

When I look to install browsers on Fedora 38 Gnome like Vivaldi (and Vivaldi snapshot too), I can simply download their .rpm file from their website and install it via Gnome Software. Super quick and easy. However, Mozilla doesn’t offer any .rpm files for Firefox Nightly that I found, so it’s not as easy or obvious to install. I’ve see this install guide here: https://www.linuxcapable.com/install-firefox-nightly-on-fedora-linux/

It tells you how to install Firefox Nightly, but also adds it via copr. Not sure how reliable/safe/or recommended random copr repos are, but I think I’d rather not use them unless I absolutely had to. My hope is to install both Nightly and Developer and see which one I’d rather use for testing purposes. Appreciate any feedback, thank you.

You can download them directly from Mozilla and unpack them in your home directory somewhere and run them from there. There is no real “installation” needed.

If you don’t want to re-download the archive from Mozilla every day, you can install Firefox nightly as flatpak provided by Redhat/Fedora maintainers.

flatpak install --from https://firefox-flatpak.mojefedora.cz/org.mozilla.FirefoxNightly.flatpakref

That way the application gets updated as part of your system updates.

Website broken.

Get it from https://www.mozilla.org/en-US/firefox/all/#product-desktop-release and run from /opt

Instructions are here: Nightly - MozillaWiki

If the flatpak is down, alternatively you could use an Ubuntu Distrobox/Toolbox

sudo add-apt-repository ppa:ubuntu-mozilla-daily/ppa -y
sudo apt install firefox-trunk -y

#copy the desktop entry
cp /usr/share/applications/firefox-trunk.desktop ~/.local/share/applications/

#run it from this toolbox
sed -i 's/Exec=firefox/Exec=toolbox-enter Ubuntu -- firefox/g' ~/.local/share/applications/firefox-trunk.desktop

# or in distrobox
distrobox-export --app firefox-trunk

But the Flatpak would by far be the better option
