TB54 the way FreeFlarum shows its default icon is that all forums have a favicon.ico
in their web root. When you upload a custom icon, Flarum won't overwrite this file, but instead it will use the <link rel="shortcut icon" [...]>
HTML head element to show the custom uploaded one. This has higher priority over favicon.ico
, and works fine in most browsers.
I believe the way Firefox works is that it does not attempt to load the favicon from <link>
, but the one present in the page's root. Unfortunately, there is not a reliable way for FreeFlarum to check if a forum had uploaded a custom favicon or not to possibly overwrite the root (FreeFlarum default) one.
I did a bit of search: https://support.mozilla.org/en-US/questions/1230644
Flarum does not use the type="image/x-icon"
. Maybe that's required by Firefox? However, someone must test that
It could also be something else, e. g.: your browser's cache, settings, etc.
