Error in console when trying to communicate with service worker in Firefox with persistant cookies disabled #17136
Description
As reported on the forum: https://forum.matomo.org/t/firefox-84-promiseerror-securityerror-the-operation-is-insecure/40299/6?u=lukas
This can be reproduced by creating a fresh firefox profile (84.0.2 in my case), and opening forum.matomo.org.

It seems like even if no service worker (for offline tracking) is set up, just trying to communicate with it fails.
Lines 6969 to 6977 in cc25c84
I guess the solution is either to make sure Matomo doesn't try to communicate with it when offline tracking is not set up (maybe even add an option to the regular tracking code if one wants to use offline tracking) or catch the promise, ignore it and document it in the offline tracking docs.
