Could not reach Cloud Firestore backend. Backend > didn't respond within 10 seconds

Question

Firestore is working fine for me unless I recompile my Angular code (hosting locally, using chrome) wait a while and then go to the browser tab where the app is. I then have the error below. If I then refresh the page it works fine.

However if I recompile my code and then immediately go to the page then it works. Basically unless I am actively on the tab when it loads it has this error.

Any ideas why?

Have tried turning of virus checker and firewall. Thinking maybe it is a browser thing.

Firestore (7.23.0): Could not reach Cloud Firestore backend. Backend didn't respond within 10 seconds. This typically indicates that your device does not have a healthy Internet connection at the moment. The client will operate in offline mode until it is able to successfully connect to the backend.

Answer 1

It is due to the new chrome background tab throttling.

I just switched to using Firefox and I no longer have the problem.

Goodbye Chrome for development.

I am a bit concerned about what happens to end users in production though. I will need to test that.
