Since some time ago, Firefox-provided Youtube notifications (which appear in the lower right) have been failing. It both no longer shows me the actual notifications at time of video release or stream start, and ocassionally spams me with a massive deulge of outdated notifications (usually around a day old or so, yet it claims they are happening at the time the notifs happen) that keep repeating for a day before sometimes being replaced by different outdated notifications. This has persistend through several pc restarts, and relogging into both my Youtube and Firefox accounts. This is still ocurring, but on top of this, notifications have now stopped appearing as popouts.

The image shows a video the notification claims was released just 20 minutes before this post was made, yet the video in reality is almost a month old.
