Not working - copy URL from firefox

Copy URL from Firefox by typing shift-command-o is not working. I get a blank OF capture window and there’s nothing in it. When it used to work, it used to have the url in the notes field and the title in the todo field.

I’m not sure when it stopped working, probably with the latest update of either the os, of or firefox.

I have a firefox extension installed call AddToOmnifocu and clicking that seems to work.

I’m running the latest version of everything.

It works from safari.
