How to Install Firefox Developer Edition on Linux

Tips & Tricks Jan 8, 2022

Do you want to install and use Firefox Developer Edition on your Ubuntu and don’t know how to go about it?!
If your answer is yes, then this article is for you. Am sure you’ve seen some documentations out there but in this one we will add Firefox Developer Edition to our Unity launcher. You’re welcome! 😉

Please follow the steps below…

Step 1: Download the .tar file from Mozilla’s website. please note the .tar file name because it changes with every update.

Step 2: Open Terminal


Step 3: cd into Downloads folder

cd Downloads

Step 4: Copy .tar file into /opt folder

sudo cp -rp firefox-67.0b10.tar.bz2 /opt

Step 5: Delete the .tar file by running

sudo rm -rf firefox-67.0b10.tar.bz2

Step 6: Go back to home directory by running.

cd ~

Step 7: Navigate into /opt folder by running

cd /opt

Step 9: Un-tar the .tar file.

sudo tar xjf firefox-67.0b10.tar.bz2

Step 10: Clean up by deleting tar file.

sudo rm -rf firefox-67.0b10.tar.bz2

Step 11: Lets change ownership of the folder containing Firefox Developer Edition /opt/firefox

sudo chown -R $USER /opt/firefox

Step 12: Open.bashrc file by running

nano ~/.bashrc

Step 13: Copy and paste this line that sets the path for the executable file: export PATH=/opt/firefox/firefox:$PATH

Step 14: Close the file Ctrl+X , then save by typing Y , when prompted for file name just click Enter

Step 15: The last step would run a command to create a Unity desktop file for your launcher. After we create this file, we’ll be able to search for “Firefox Developer Edition” in your Unity launcher to start up our browser.

cat > ~/.local/share/applications/firefoxDeveloperEdition.desktop <<EOL
[Desktop Entry]
Name=Firefox Developer Edition
MimeType=text/html;text/xml;application/xhtml_xml;x-scheme-handler/http;x-scheme-handler/https;x-scheme-handler/ftp; X-Ayatana-Desktop-Shortcuts=NewWindow;NewIncognitos;

Wow! that was a lot of commands. 😪

The browser should show up when we click show application in Unity launcher.
ℹ️Bonus Step: If you want you can now add it to favorites by right clicking the browser Icon. 👏
