Installing Firefox Developer Edition in Linux Mint

22nd April 2018

Having moved beyond the slow response and larger memory footprint of Firefox ESR, I am using Firefox Developer Edition in its place, even if it means living without a status bar at the bottom of the window. Hopefully, someone will create an equivalent of the old add-on bar extensions that worked before the release of Firefox Quantum.

Firefox Developer Edition may be pre-release software with some extras for web developers like being able to drill into an HTML element and see its properties, but I am finding it stable enough for everyday use. It is speedy too, which helps, and it has its own profile so it can co-exist on the same machine as regular releases of Firefox like its ESR and Quantum variants.

Installation takes a little added effort though and there are various options available. My chosen method involved Ubuntu Make. Installing this involves setting up a new PPA as the first step and the following commands added the software to my system:

sudo add-apt-repository ppa:ubuntu-desktop/ubuntu-make
sudo apt-get update
sudo apt-get install ubuntu-make

With the above completed, it was simple to install Firefox Developer edition using the following command:

umake web firefox-dev

Where things got a bit more complicated was getting entries added to the Cinnamon Menu and Docky. While the former was sorted using the cinnamon-menu-editor command, the latter needed some tinkering with my firefox-developer.desktop file found in .local/share/applications/ within my user area to get the right icon shown. Discovering this took me into .gconf/apps/docky-2/Docky/Interface/DockPreferences/%gconf.xml where I found the location of the firefox-developer.desktop that needed changing. Once this was completed, there was nothing else to do from the operating system side.

Within Firefox itself, I opted to turn off warnings about password logins on non-HTTPS websites by going to about:config using the address bar, then looking for security.insecure_field_warning.contextual.enabled and changing its value from True to False. While some may decry this, there are some local websites on my machine that need attention at times. Otherwise, Firefox is installed with user access so I can update it as if it were a Windows or macOS application, and that is useful given that there are frequent new releases. All is going as I want it so far.
