I want to set 2 preferences regarding syncing as default preference for all (new) profiles. 1. sync toolbar layout. 2. set my own sync server path. I already know how to do this via about:config manually per user. I want to have these 2 preferences by default for all users. On Ubuntu 21.04, I followed these instructions to the letter, but it has no effect, tested on a newly created profile: https://support.mozilla.org/en-US/kb/customizing-firefox-using-autoconfig I created: /usr/lib/firefox/defaults/pref/autoconfig.js And it contains exactly what is in the instructions. Also created: /usr/lib/firefox/firefox.cfg Looks like: ``` // IMPORTANT: Start your code on the 2nd line defaultpref("services.sync.prefs.sync.browser.uiCustomization.state","true"); defaultpref("identity.sync.tokenserver.uri","https://ffsync.mydomain.tld/token/1.0/sync/1.5"); ``` Then I create a new profile and check via about:config, unfortunately the first preference doesn't exist (note it doesn't exist by default) and the other is not applied, I still see Mozilla sync server path. How can I set these 2 customisations globally. for all future users (preferably also current users)?

defaultpref("services.sync.prefs.sync.browser.uiCustomization.state","true");
defaultpref("identity.sync.tokenserver.uri","https://ffsync.mydomain.tld/token/1.0/sync/1.5");

defaultPref("services.sync.prefs.sync.browser.uiCustomization.state","true");
defaultPref("identity.sync.tokenserver.uri","https://ffsync.mydomain.tld/token/1.0/sync/1.5");
