I am running the latest version of Cinnamon on my Arch desktop with the latest version of Firefox. However, I am not receiving notifications from websites that I have expressly enabled notifications on. For example, my Mastodon instance doesn't give me notifications when something has been favorited or boosted. For that matter neither does my Lemmy instance. I have given these instances the proper permissions to allow notifications and still nothing. This happens with some other websites but it is hit and miss.

As I am not so familiar with the innards of Cinnamon, would somebody be so kind as to point me in the right direction?

Thanks in advance!
