Installing FireFox Developer Edition on Ubuntu

October 14, 2019

Firefox Developer Edition contains features not currently released to the regular version of Firefox. Its main attraction to me is Mozilla’s respect for my privacy and having an additional browser to segregate my life into. I use Firefox for my personal life and Firefox Developer Edition for work related accounts and activity. However, using the Webpack Dev Server I find that Firefox Developer Edition consumes increasing amounts of memory until my machine freezes. Therefore I also use Chrome for development. However, I often turn to Firefox Developer Edition for inspecting pages.

Here is how to install Firefox Developer Edition on Ubuntu. I’m using Ubuntu 18.04 but this same process should work on earlier and later versions.

Get Firefox Developer Edition

Go to Firefox Developer Edition
Click the ‘Firefox Developer Edition’ (currently a large blue button)
Save the file to Downloads

Extract contents if the compressed file

tar -xvf firefox-*.tar.bz2

Rename extracted folder to firefox-dev and move to /opt

sudo mv firefox /opt/firefox-dev

Make a Desktop Entry

So that you can launch Firefox Developer Edition by pressing the Super/Windows key and typing ‘firefox’, make a desktop entry in: ~/.local/share/applications/firefox-dev.desktop

cd ~/.local/share/applications
touch firefox-dev.desktop
gedit firefox-dev.desktop

Past in the below contents into the file.

[Desktop Entry]
Name=Firefox Developer 
GenericName=Firefox Developer Edition
Exec=/opt/firefox-dev/firefox %u
Terminal=false
Icon=/opt/firefox-dev/browser/chrome/icons/default/default128.png
Type=Application
Categories=Application;Network;X-Developer;
Comment=Firefox Developer Edition Web Browser.

Save the file and launch Firefox Developer Edition
