Go to the browser menu and select "Settings." On the left, click on "Privacy & Security." Scroll down to the "Permissions" window, and select "Notification." If you want to disable notifications, check "Pause notifications until Firefox restarts." Thus, notifications will not appear until you restart Firefox.

While maybe not completely helpful you could also check you didn't hit a command or button combo to disable them in firefix
it already has on it , and its allowed is on
hit and command has no effects... all notifications work except for that pop up that usually it does (when im not in window) even im on or off jsp, the message will pop up on lower right side but it has not pop up.
