I love Firefox. I use Firefox Nightly as my daily driver.

Recent changes with how Firefox uses its profiles has meant I’ve now uninstalled the stable release of Firefox I had installed with my package manager.

The other motivation to get Firefox Nightly to play nice with GNOME was the new nightly logo.

To install Firefox Nightly I donwloaded the latest release and extracted it to /opt/firefox. I then made the firefox folder owned by my user account so firefox could update itself. GNOME uses .desktop files to populate its launcher and dock. I created this file and saved it to ~/.local/share/applications/firefox.desktop:

[Desktop Entry]
Version=1.0
Name=Firefox
Comment=Browse the World Wide Web
Icon=/opt/firefox/browser/icons/mozicon128.png
Exec=/opt/firefox/firefox %u
Terminal=false
Type=Application
Categories=Network;WebBrowser;
Actions=PrivateMode;SafeMode;ProfileManager;

[Desktop Action PrivateMode]
Name=Private Mode
Exec=/opt/firefox/firefox --private-window %u

[Desktop Action SafeMode]
Name=Safe Mode
Exec=/opt/firefox/firefox --safe-mode

[Desktop Action ProfileManager]
Name=Profile Manager
Exec=/opt/firefox/firefox --ProfileManager

Hopefully this useful to others.
