You can try Firefox from the official Mozilla server if you currently use a version from the repositories of your Linux distribution to see if it behaves differently.

Thanks for the suggestion. I downloaded firefox-101.0.1 and it works fine there, even after restoring copying over data from the main firefox (http://mzl.la/1xKrzkF) and syncing my firefox account.

I think this may be an issue with firefox-102? Would have to redownload a fresh copy to confirm.

It's either there a bug in 102 or the update process broke something. I've always been wary of updating.

I think i'll just delete the 102 version and continue using 101.

Thanks for your help.

I just downloaded a fresh copy of firefox 102 and i had the same problem. So I think this means there is a bug in 102, or the process for changing location was changed?

Steps: 1. Download 102: https://download-installer.cdn.mozilla.net/pub/firefox/releases/102.0.1/linux-x86_64/en-GB/firefox-102.0.1.tar.bz2

2. Extract to folder

3. Click on firefox

4. Open https://browserleaks.com/geo, and grant permission. It should show the location provided by isp

5. open about:config and edit "geo.provider.network.url" to: data:,{"location":{"lat":84.552145,"lng":8.259976},"accuracy":1000}

6. Go back to https://browserleaks.com/geo and reload multiple times using ctrl+shift+r after granting location access, it still shows location seen previously in step 4, even after restarting browser.

7. The process works as expected in firefox 101

resolved by also setting geo.provider.use_geoclue to false
