Currently Firefox is allowing users to specify No Proxy for field which allows users to bypass proxy, for example by typing .com we can bypass all .com websites
how to disable this No Proxy For in GPO settings ? there are multiple users bypass the proxy and access to URL that not filtered by our proxy server

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.
by selecting the No proxy setting, all the URL will get through i want the firefox using the system proxy and the no proxy for greyed out so that user cant bypass the proxy to access to any restricted URL
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
