I’m on Firefox Developer Edition and already have the new icon. However, it’s smaller than the other icons. It’s kinda in an uncanny valley territory because it’s close to the right size, but not quite. Really visually annoying and I’d strongly prefer the old one back or the size to be fixed. It’s smaller both in the dock and in the Command-Tab screen.
A recent update changed the app icon for Firefox to a black background instead of the normal light (see attached pic - the Thunderbird icon is proper). I do *not* use dark mode, so this looks bad, is an eyesore and frustrates me.
Also Mozilla devs need to realize that not everyone is using the latest macOS on purpose -- some people like sane GUIs -- so styling the icons to favor just one version is frustrating. Looking at my dock, now it seems as if something is wrong with Firefox...
@spearsonthank you for your advice on changing the icon. I would just clarify that you need to drag the .icns to the small icon at the top of the "get info" window, not the large icon at the bottom. I found some round icons online and switched it. I feel that the rounded square icons are a step back. If we have the ability to have transparent icons, why not utilize that?
I agree, V106 Icon looks EXTREMELY disproportionate when compared to other icons in the dock. It's not "Tall" enough - I am assuming this is an optical illusion (because of the dark background), but please modify it to make it look more native - right now it is extremely out of place. Needs another revision for sure.
