Firefox Apparmor Profile

I'm running Ubuntu Mate 19.04. I want to enable apparmor for Firefox. I found an existing profile in /etc/apparmor.d/usr.bin.firefox, which I enabled by deleting /etc/apparmor.d/disable/usr.bin.firefox.

It is mostly working, but I've noticed one issue. I can't open my downloads from Firefox. I can't even "Open Containing Folder" on a download. Both ask me what application I want to use to perform the action.

Here are the errors I see from Firefox when I run it. Those first 4 apparmor errors happen as soon as I launch Firefox. The last 3 "cannot launch" errors happen when I try and open downloads.

Here is my full policy:

I tried to allow those ListNames methods myself, but I really have no idea what I am doing. I also tried to run firefox with aa-genprof, but I never saw these violations pop up while I did that.

Any ideas?
