Comment 9 for bug 1777070

I got it working by adding the 2 lines at the end of the /etc/apparmor.d/usr.bin.firefox just before the closing brack "}". Without these lines, I had to use another workaround by disabling Apparmor completely on Firefox with a command like "sudo aa-complain /usr/lib/firefox/firefox" or using the official Firefox binary from Mozilla instead of the Ubuntu package.

I saw Daniel wrote "this is not a great way of working (malware could write to that location and then load in code)" but do you have an idea how to make it more secure?

When will the fix be added officially to the Firefox Apparmor profile?
