How to Install Firefox Developer Edition on Ubuntu & Linux Mint

Firefox developer edition, which is a browser built specifically for web developers, was first introduced by Mozilla back in November 2014. It streamlines the development workflow so developers don’t need to bounce between different platforms and browsers. This browser comes preloaded with many web developers tools such as WebIDE and Valence which allows developers to debug other browsers and apps directly from within the Firefox developer edition.

By using the Developer Edition, you also gain access to tools and platform features at least 12 weeks before they reach the main Firefox release channel. It can run alongside your existing Firefox browser.

The latest version is 50.0a2, released on August 5, 2016. Changes includes:

  • Find in page now supports a mode to search for whole words only
  • New preference for allowing Ctrl+Tab to cycle through tabs in recently used order
  • Improved printing by using the Reader Mode
  • Emoji for everyone! Firefox will use built-in Emoji on operating systems without native Emoji fonts (Windows 8.0 and lower and Linux)
  • Use accel-(opt/alt)-r as the reader mode keyboard shortcut
  • changes for web developers can be found here.

Note that Firefox developer edition may missing some standard Firefox features. For example, it doesn’t have the leaked password alert feature, if you use the Firefox built-in password manager.

Install Firefox Developer Edition on Ubuntu/Linux Mint via Ubuntu Make

You can also log out and log back in, then the icon will show you in your application menu.

    Hi. I got “ERROR: Download page changed its syntax or is not parsable” when trying to install using umake.

      This is a new bug in ubuntu-make. To fix it, edit a file.

      sudo nano /usr/lib/python3/dist-packages/umake/frameworks/

      Find this line.

      reg_expression = '< href="(.*)" title'.format(tag_machine)

      Replace it with the following line.

      reg_expression = r'href="(S+os=linux{}&lang=S+)"'.format(tag_machine)
