Why firefox forgets my web notifications for Twitter

Question

Why Firefox forgets my web notifications for Twitter, every-time I restart my system.

And I have failed to understand this weird behavior not less than 10 times. Just curious to know if this is a Firefox bug or am I missing something.

I have also read Firefox Support for Push Notifications & Disable Web Notifications

Attached are the screenshots to make it more clear.

1. First one, is for the Twitter Web Notification
2. Second one, is for the Firefox Notification Setting

FYI:

• It never happened with Chrome but it eats lot of my cache memory, so I removed it.
• I have also updated firefox to 58.0.2, but nothing improved.
• Also, checked this answer here on superuser

Any help/suggestions?

Answer 1

I found the solution yesterday, when I was checking some of my Background Apps in Windows 10. And I found Twitter was turned off.

So, just Turn it On and you are good to go. :)

Settings > Privacy > Background Apps > Twitter
