Firefox.app wants to use the font “QuickType Mono on the volume “my disk”. This font is not installed. Allow Firefox.app to use this font? Why is Firefox asking me this, I have the font.

Every time I start Firefox, I get this question:

I do have the font installed.

Move the selected User fonts to Computer fonts

You do not have to move all your fonts from User fonts to Computer fonts within Font Book. Just do the following:

In Firefox Preferences: 1. Deselect Auto Activation 2. Make sure that the font that Firefox is asking permission to use is activated......if it isn't, then right click on the font and activate it. 3. Exit Firefox Preferences and re-launch Firefox. Issue should be corrected.
