Hi all, I used to have pihole on an actual rasperry pi for a long time with no problems, and have recently switched to docker. However, a couple of weeks after doing so I noticed that there are now an excessive amount of requests to location.services.mozilla.com - nearly 86000 in the last 24 hours alone.

I have always used Firefox, but this seems like weird behaviour. I have Pihole set up as the DNS server in the router settings, but am not using the pihole as a DHCP server.

Let me know what logs to post, if any. Thanks.

FWIW, I do not run pihole.

That behavior is in line with with a service repeatedly trying and failing to connect. If it did connect, the number of tries would be much lower. When Reddit started using Branch Analytics people were reporting similar numbers.

The fix, IIRC, is to return a response with a null value. Instead of sinkholing it, you want to make it think the connection went through but the service was down.

Pihole is reporting that it is letting those queries through, not blocking them.

I just put FF nightly on my phone and my firewall (on phone) is blocking attempts about every 1 minute from
location.services.Mozilla(.)com I am getting many more attempts from

incoming.telemetry.Mozilla(.)org up to 3 per second perhaps that is listening for responses? I see no obvious way to change either of those in about:config

Sorry I can't be of more help

#Solution:

Turns out the requests were coming from Immich (in another docker container) breaking after an update. I just deleted the containers. May or may not try a fresh install later.
