[SOLVED] Anyone know how to import preferences into Firefox on multiple computers ?

[Deleted member 2783327]

I am upgrading our PCs from 78esr to 91esr.
I have a set of about 70 preferences I need to import
I don't want to visit 250 PCs one at a time and make the changes one at a time via about:config
I can't just use a single default prefs.js because any or all of the PCs can have preferences specific to that user/PC
I've asked on Mozilla forums but got no answers.

Any one know how to import a set of preferences, automatically?

Group policy should work for this https://support.mozilla.org/en-US/kb/customizing-firefox-using-group-policy-windows

Firefox ADMX Group Policy Administrative Templates

Sample on how to do it is here https://techexpert.tips/windows/gpo-mozilla-firefox-configuration/

Thanks for that.

Mozilla has only provided partial group policies, even for v91esr. Of the 70 or so preferences I am trying to set, only 11 have corresponding have policy settings.
