Kathy and I did some triage of this ticket because we thought it might be a macOS-only bug, but that is probably not true. It seems to be related to first party isolation of permissions. Using the following page for testing, notifications started to work after I changed privacy.firstparty.isolate to false:

On that page, grant permission for notifications when prompted and then click the "Notify me!" button.

Arthur, any ideas?

We got a user on #tor today reporting something similar on Linux which has probably the same underlying issue:

1) start Tor Browser
2) go to a website that offers web push notifications, e.g. ProtonMail https://protonirockerxow.onion, and log in
3) after successfully logging in, the Tor Browser asks "Will you allow protonirockerxow.onion to send notifications", click "Allow Notifications".

Expected result: every time I receive an email, I should get a notification (via libnotify or something like this) that looks just like any other KDE desktop notification.

Instead of this expected result, I get no notification at all.

Arthur, can you pick that up? I think it could be relevant to upstreaming the permissions patch you are working on.

I confirm that, after changing privacy.firstparty.isolate to false, notifications work again on Linux/KDE.

This probably seems related to the permissions patch because I don't have any problem with it on Nightly with FPI enabled.

I just tested notifications with TBB 8.5a4 and First Party Isolation enabled, and notifications did not work.
I don't know how different TBB alpha and TBB nightly currently are though, so I don't know if this bit of information helps.
