Using Linux Mint 21.3 Virginia (Kernel: 5.15.0-113-generic) on Cinnamon Desktop 6.0.4

It seems to work with Facebook Messenger in a Container Extension. Will test with this other website that does have a sound notification, but only a Push Notification at the title bar. Will check tomorrow and review.

Are there plans to update it w/ sound notification?
Does anyone know of an addon with similar functionality?

It would be nice if this addon can notify other changes too, for example when some text in the page appears or disappears. sometime the title never changes.

MALA

can you add some sound to notifications?

Excellent design and very user friendly

las notificaciones no paran de saltar (y no muestra el texto en Hangout)

cool

Useful application. The only real thing keeping me from giving a full 5-stars is that I want the ability to NOT show notifications on pages that are currently active.

For example, a mail website. The title bar might say "5 unread", but once I read one email, the title changes to "4 unread" at which point I get a notification on my desktop. I want the ability to either not show that via settings or as a permanent change.
