Firefox not showing Facebook Notifications?

Hi!

Just a very curious question.
Firefox never manage to show when my SO sends a chat message on Facebook via the KDE notifications.

It works great for extensions, Push Notification test, other websites etc. But just Facebook refuse to work? (Curse or a blessing?)

Anyone got any idea? I tried for funnsies to to try firefox-bin to see if it was the original firefox that was broken, but nay.

I’ve tried these:

I don’t have null, and tried that both true and false.

So any tips?

Do a web-search for this:

firefox add-ons facebook notify

There seem to be a variety of FF-Add-Ons available.

But mind: Curiosity killed the cat. :wink:

I’ll check! Thanks
