The thing is, Firefox dev edition is not available on the default system repository so if you want to install it, you have to do it manually.
Let's get right into it.
1. Open terminal
2. Download and unpack
wget "https://download.mozilla.org/?product=firefox-devedition-latest-ssl&os=linux64&lang=en-US" -O Firefox-dev.tar.bz2
sudo tar xjf Firefox-dev.tar.bz2 -C /opt/
rm -r Firefox-dev.tar.bz2
3. Install
sudo ln -s /opt/firefox/firefox /usr/local/bin/firefox-dev
4. Run
firefox-dev
Now at this point, you have installed Firefox dev on your system and you can run it with the above command but if you want to create a shortcut(which you should), then follow along.
5. Creating Shortcut
vi Firefox-dev.desktop
If you don’t know how to use vi editor :
Press “i” to enter insert mode
copy-paste the lines given below( ctrl +c / ctrl+v )
Paste these lines inside the file :
[Desktop Entry]
Name=Firefox-developer-edition
Exec=/usr/local/bin/firefox-dev
Icon=/opt/firefox/browser/chrome/icons/default/default128.png
comment=browser
Type=Application
Terminal=false
Encoding=UTF-8
Categories=Utility;
- press “ESC” to move out of insert mode.
- now type “:wq” and press enter key to save and exit.
Finally :
sudo cp Firefox-dev.desktop /usr/share/applications/
6. Updating
To be honest with you using Firefox Developers Edition as your default browser is kinda annoying since it asks for updates very often and you have to do it manually.
But if you wanna update it, don’t download it from the browser, just run these commands:
wget "https://download.mozilla.org/?product=firefox-devedition-latest-ssl&os=linux64&lang=en-US" -O Firefox-dev.tar.bz2
sudo tar xjf Firefox-dev.tar.bz2 -C /opt/
7. Removing
In some case, you wanna completely remove Firefox dev from your system:
sudo rm -r /opt/firefox/
sudo rm /usr/local/bin/firefox-dev
sudo rm /usr/share/applications/Firefox-dev.desktop
rm ~/Desktop/Firefox-dev.desktop
