User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:102.0) Gecko/20100101 Firefox/102.0

Steps to reproduce:

If the "Enable DNS over HTTPS" setting is enabled during VPN connection then FireFox leaks DNS. Disabling the setting stops DNS leaks.

Actual results:

If the "Enable DNS over HTTPS" setting is enabled during VPN connection then FireFox leaks DNS. Disabling the setting stops DNS leaks.

Expected results:

This is a faulty implementation because the user won't have the benefit of DoH if the setting is disabled. This should not be an either-or proposition, FireFox should have the intelligence to determine whether or not a VPN is in use and then enable/disable DoH accordingly.

The Bugbug bot thinks this bug should belong to the 'Core::Networking: DNS' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.
