Thank you @jahilldev,

Yes, I understood the logic behind creating the request.

I have created the Analytic Endpoint, but still, the Firefox Private Mode browser is not working.
If I access it from a normal browser, I can see real-time data so the endpoint that I created is working.

Any help is highly appreciated.

Thanks!

@CharbelNemnom It's difficult for me to help without knowing more context around exactly what you're doing.

Given "Firefox Private Mode" does its best to block tracking, it could be that something you're doing is triggering their logic somehow.

Anecdotally, I know people have achieved this by using the custom endpoint, but I haven't personally.

I'd suggest we continue this via an issue below, given this is a little off topic for this Gist.
https://github.com/jahilldev/minimal-analytics

If I have a minute, and you can provide some kind of repo outlining exactly what you're doing, I might be able to help, but can't guarantee anything, I'm afraid.

My initial suggestions:

  • Attempt to find out exactly what conditions Firefox are using to constitute tracking
  • Debug where in the code the request is being blocked, if at all
  • Experiment with different endpoint names, given this is likely the primary condition they're using, in conjunction with known tracking domain names

Let me know how you get on (in a seperate issue, please!)

Thanks 👍

Thank you so much @jahilldev,

I have opened an issue on your repo: https://github.com/jahilldev/minimal-analytics
So we can continue troubleshooting there.

Many Thanks!
