I installed Firefox by doing this:

 1. wget
 2. tar -xjvf firefox-42.0.tar.bz2
 3. sudo rm -rf /opt/firefox*
 4. sudo mv firefox /opt/firefox
 5. sudo ln -sf /opt/firefox/firefox /usr/bin/firefox

When I run it on terminal, the only option that I have when right click on Firefox's icon on Dock is "Close". How can I add Firefox to Dock?

    Why aren't you installing firefox from official repositories by typing sudo apt-get install firefox into terminal or by installing from software center?

  • @Rafael, it was a bad idea indeed. How do I fix this?

To get an icon on plank (and in slingshot) an app needs to have a corresponding .desktop file in /usr/share/applications/. The desktop file also handles MimeTypes and lets you specify additional menu options (such as 'Open New Window' etc.)

Note: If you install firefox from the apt repositories with sudo apt-get install firefox it will update to v42 and the desktop file will be created for you. Since you have already installed it by other means, here is the firefox.desktop file it includes.

    Thanks, this solution worked for me. I added the firefox.desktop file to ~/.local/share/applications Sep 16, 2019 at 9:15
