[CHANGE] Wake tabs notification bundled instead of per page

[Blastinburn]

What would you like to change

When tabs wake up a notification is displayed for each tab that woke, regardless of the number of tabs that woke up at the same time.

What would you like to see instead

If more than 1 tab wakes up at the same time (say browser start) then only 1 notification appears saying how many tabs were opened.
This is the behavior of TabSnooze which I used to use before switching to firefox. (And has since been removed from the chrome store.)

What is your specific use case (if applicable)

If I end up having a large number of tabs open at once, say telling them to open on the weekend over the course of a week, there can be up to a minute or 2 of notifications and ding sounds as each one plays sequentially.

Which browser / OS do you use

Firefox / Windows 10
