I really wish I knew how to fix Firefox on Android displaying rectangles instead of Unicode(?)! I tried a few things but it's been stuck this way for months. https://witches.town/media/Fkb8xlME_HSaSr5oAWw
I think it happened when I unchecked "Download remote fonts" in Firefox settings, but it refused to come back no matter what I tried, so... I guess a uninstall/reinstall is in order anyways!
In the end, the only reason I even bothered enough to reinstall was because I wanted to see Witches Town's upsidown purple stars for favouriting posts...!
