Hey, there!

I've recently enjoyed the Firefox Developer Edition. It has cutting-edge features for web programming and ahead in terms of updates and more features.

In this blog, we'll discuss how I installed FDE on my Ubuntu OS. I chose not to include the PPA method since I've read that it may not be stable when it comes to specific versions. You can also install FDE via Ubuntu Make, but we're not going to discuss that here. Here's a link if you want to install it the non-manual way.

Here are the instructions I've followed while installing FDE (Manual method):


  1. You should have another browser open when installing Firefox. Why? Because you're going to replace the default with the DE version.


Step 1. Download the .tar file from the FDE website

Step 2. Open your terminal (Ctrl + Alt + T) and cd into your Downloads folder

cd Downloads

Step 3. Copy the .tar file to the /opt folder

sudo mv -rf firefox-90.0b5.tar.bz2 /opt

Step 4. Cd to your home directory

cd ~

Step 5. Navigate to your /opt folder

cd /opt

Step 6. Extract the .tar file in that folder

sudo tar xjf firefox-90-0b5.tar.bz2

Step 7. Change the ownership chown of the folder to root (so that it gets updated along with System Updates)

sudo chown -R $USER /opt/firefix

Step 8. Open the .bashrc file with nano

nano ~/.bashrc

Step 9. Paste this command line at the end of the document to set the path for the executable file. Press Ctrl + S to save afterward.

export PATH=/opt/firefox/firefox:$PATH

Step 10. Create a desktop file for your launcher. Simply paste all of the commands

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;

And that's it! Your FDE should show up in your Unity Launcher.

Tell me how it went. 👏
