After wiping my Mozilla Firefox profile data everywhere, including AppData Local and Roaming profile directories, Firefox autofill stopped saving and/or synchronizing my address information. The address autofill options disappeared entirely from Firefox "Privacy & Security" section. I checked about:config, which had "services.sync.engine.addresses" and "services.sync.engine.addresses.available" set to "False". I set them to "True", but that only restored the address synchronizing setting in Firefox "Sync" section, not in "Privacy & Security" section. Syncing did not restore the address autofill options for "Privacy & Security" section and neither did changing other autofill and address-related entries in about:config. Starting a fresh new profile yet again didn't help. Could this be caused by network-wide block of "location.services.mozilla.com" ? That domain became blocked a while back and there was no way around it, not even with DNS-over-HTTPS, but back then address autofill was working just fine without accessing that domain. How can I bring back the address autofill portion of "Privacy & Security" section???
