More observations: other websites that tell you your geolocation and IP address and whatnot are providing mixed results. Some are showing the one I selected and others are showing my VPN location ( I use Mullvad btw, if that makes any difference).
This is most likely because some websites are determining your location via IP address, some are determining your location via the geolocation apis. Sophisticated sites use a combination, date/timezone api, offset, Daylight savings time, etc. The original intention of this extension was to align your Browser geolocation to your VPN IP so that all locations you are emitting are synchronized.
