Geospoof: a firefox add-on for convenient geolocation privacy

Your setup sounds solid and your workaround is correct. Manually setting the city to your router VPN’s location is exactly what VPN Sync would have done automatically. The browser-level spoofing should be working fine.

VPN Sync failing in a multi-hop setup may be a limitation, I haven’t checked that scenario. To help debug, can you share your VPN provider so I can try to replicate this? If you want to help me diagnose the VPN Sync issue, here’s what to do:

1. Enable debug logging: Open the GeoSpoof popup → Details tab → Advanced → enable Debug Logging and set verbosity to Debug
2. Open the extension inspector: Go to about:debugging in Firefox → This Firefox → find GeoSpoof → click Inspect
3. Capture logs In the inspector: go to the Console tab and clear it. Then click “Sync Now” in the popup. Copy and paste all the log entries.
4. Capture network requests: Still in the inspector, switch to the Network tab and clear it. Click “Sync Now” again. Right-click any request → Save All As HAR to export the network log.

Send both to support@geospoof.com and I’ll try to help as best I can.
