hi yvery, try this method, which now shows you: Start Firefox, open the menu at the top right and go to Options> Advanced> Network, click on Settings, select No proxy and select via OK. I am waiting for improvements.

I've moved the thread to Firefox for Enterprise support.

That would possibly be about locking network.proxy.no_proxies_on via autoconfig.cfg.

I found some bug reports about proxy prefs, but I can't figure out how locking this specific pref would work via GPO.

  • bug 1557717 - Locking network.proxy.no_proxies_on doesn't stick when switching between proxy types.
  • bug 1505330 - Single lockPref blocks all proxy configuration page
