We have Windows 2008 RDP server with Mozilla Firefox 57.0.1 64 bit installed. How to install an addon for all users?


Instead of launching the .xpi installer, copy the .xpi file into a standard extension folder

  • Global (x64) C:\Program Files\Mozilla Firefox\browser\extensions\{appID}.xpi
  • Global (x86) C:\Program Files (x86)\Mozilla Firefox\browser\extensions\{appID}.xpi
  • Per user %AppData%\Mozilla\Extensions\{appID}\

where the {appID} must be the application ID of a signed Firefox add-on.

  • How do I get the {addID}? – real_sm Dec 13 '17 at 18:29
  • Never mind, installed using other manual. – real_sm Dec 13 '17 at 19:27

Installed the addon using this manual: https://developer.mozilla.org/en-US/Add-ons/WebExtensions/Alternative_distribution_options/Add-ons_in_the_enterprise

  • Doesn't really explain which method you used. The standard extension folder is one of the options there, too. At least explain how you solved this. – Esa Jokinen Dec 13 '17 at 19:36

    @EsaJokinen Standard extension folder method is on the other link: developer.mozilla.org/en-US/Add-ons/WebExtensions/… I used the registry method from the above link, because I couldn't even download the xpi file (seems like they disabled downloading from other browsers). Also there's a note: >To install an add-on for all users of a Windows computer, see Installation using the Windows registry. – real_sm Dec 15 '17 at 10:23
