Alright, there's a few things to unroll here but the summary is "everything described is expected".

For Firefox Beta, the 20 second notification is the old, non-native style notifications; you need to set `alerts.useSystemBackend = true` in Firefox Beta's `about:config` to get native, action center notifications. The same is true for stable Firefox.

That said we can ignore Firefox Beta, the reason I suggested checking it was because I misunderstood what your problem was. There's nothing of note in Firefox Beta with respect to the current problems.

I checked Youtube's source code, and as expected the reason notifications don't dismiss on Chromium browsers is because Youtube is using the `Notification.requireInteraction` API. We don't currently support this API, but I'll probably investigate if it's straightforward to support for native Windows notifications in the near future. You can follow that [here](https://bugzilla.mozilla.org/show_bug.cgi?id=1794475).
