Show all possible PDF applications
I have written several local shell scripts to handle how to open a PDF. When Firefox asks me how to open a PDF, I would like to see all of them in the dropdown menu. However, I can only see the one that I had previously selected, so whenever I want to use another one, I have to click "Other..." and go through my filesystem to their respective paths. Is there a way to permanently make several applications appear in that dropdown menu?
You can try to set each of them one after the other as the default application to see if that makes Firefox show them in the list.
