I work in a Windows enterprise environment that want to implement the following setting in Firefox 69.03: user_pref("network.trr.mode", "5");

I have a one line user.js file and place it where the prefs.js is located. The changed setting is never picked up by Firefox. What am I doing wrong? Thanks.

hi, please try the following instead (no quotes around the integer):

user_pref("network.trr.mode", 5);
