This is a little-known edition of Firefox focused on web developers.
It includes a few add-ons (like Valence) for web developing and includes future technologies that aren’t included in regular Firefox Quantum.
It is delivered from nightly builds.
It gets features that have stabilized over the last six weeks.
Installation on LinuxYou can install Firefox Developer Edition via the UMake project.
For that you will have to add the PPA for UMake manually:sudo add-apt-repository ppa:ubuntu-desktop/ubuntu-makesudo apt-get updatesudo apt-get install ubuntu-makeumake web firefox-dev -r # installs firefox dev editionTo add the application in a GNOME desktop, you need to make a desktop entry as follows:#!/usr/bin/env xdg-open[Desktop Entry]Version=1.
0Type=ApplicationTerminal=falseName[en_IN]=Firefox Developer EditionExec=/home/shukant/.
local/share/umake/web/firefox-dev/firefoxName=Firefox Developer EditionIcon=/home/shukant/.
pngBe sure to change the file paths to the ones on your system.
Specifically, change the “/home/shukant/” part to “/home/your-username”.
Windows and macOSYou can use the Firefox installer directly: https://www.
NOTE: Linux users can use the link too — although it will be more complicated to install the .
deb package directly using your package manager.
In addition, explain whether you might switch from Chrome to Firefox for debugging your web applications!!!Shukant Kumar Pal (@ShukantP) | TwitterThe latest Tweets from Shukant Kumar Pal (@ShukantP).
