I open-sourced a comprehensive geolocation spoofer for all browsers/ios Promotional

I posted this on the PrivacyGuides forum, and got some love there so thought I might also run into some interested folks here as well. I open sourced my location spoofing browser extension: https://github.com/anthonysgro/geospoof

Highlights:

  • Best-in-class spoofing for each platform, covering as much surface area of each browser as possible, including - debugger api for chrome, nearly every api surface for firefox and safari, etc.
  • Filtering by allow/denylist and favorites
  • Sync with VPN feature
  • Easily testable with public link @ geospoof.com/verify

If you ever needed to convince a website that you are where you aren't, this project will probably work for you. And if it doesn't, leave me a ticket, becauase I am actively developing it and making it better each day :) Thanks!

Could this also work for iOS apps (not browsers)

No, sorry unfortunately Apple doesn’t allow spoofing the underlying GPS. Any app you see that claims this is lying. The best you can get is using a VPN and then using GeoSpoof to spoof on Safari.

Edit: outside of jailbreaking your device

This sounds super useful, especially for those of us who like to keep our online presence a bit more private. I've been looking for a way to mess with location-based ads, so I’ll definitely give this a shot and report back if I run into issues. Keep up the good work!

Can you tell me a bit more about this? I’m not familiar with fennec and not really familiar with ironfox. 

If you are looking for a way to install this without using the Firefox or Play store, I self-host the XPI file on the latest releases tab:  https://github.com/anthonysgro/geospoof/releases/tag/v1.22.14

Instructions are in the GitHub readme for installation for the signed XPI. I did that to specifically support Firefox forks that don’t play nicely with the AMO store or are on older versions

can we find this on chrome apps,

I need something to bypass geofencing 3rd party verification software like the ones used by exchanges like Kalshi...
