[Discussion] Usage with Browser Reader Modes

[D1yt]

Hi, I’d like to quickly share a tutorial on how to add Fast Fonts to Firefox Reader Mode as selectable fonts.

1. Install the fonts.
2. Open Firefox’s about:config page.
3. Search for reader.font_type.values.
4. Set the value to:

["sans-serif","serif","monospace","Fast_Sans","Fast_Serif","Fast_Mono","Fast_Sans-Dotted","Fast OpenDyslexic"]

Make sure to replace these with the actual font family names installed on your system.

5. When viewing a Reader Mode–compatible page, you can now switch to those fonts in the Reader Mode font menu.

Does anyone know whether there is a similar working method for adding custom fonts to Firefox for Android?
