Hi marcia5, what happens now? For example: * VPN off: Firefox works normally * VPN on: Firefox cannot find servers, websites time out, pages are incomplete, etc. If Firefox cannot find servers, perhaps check whether this is due to Firefox using DNS over HTTPS, which is a way to look up server addresses bypassing your system's normal DNS servers. This article describes where to find that setting and turn it off if it's currently on: [[Firefox DNS-over-HTTPS]] (section titled "Manually Enabling and disabling DNS-over-HTTPS") Any progress so far?
