The lemmy.world favicon is not being displayed in Firefox (but works in Chrome/ium). I’m pretty sure that this is because the currently used image is too large (it’s 4267x4267 pixels and 365K, far larger than is needed for a favicon). Another instance encountered the same issue, and their favicon works now (after being reduced in size).
Having the same issue.
The icon is too large. I don’t think anyone needs a 4k favicon, can someone scale it down to 512x512 or so?
