Ah, a script/plugin as a workaround? Maybe, but do the sites with animates favicons deserve so much attention? Do you know any useful web site with animated favicon?

GMail has a cool extension in Labs that changes the favicon to display the number of unread messages. So that's a use-case.

That's useful, My webmail (yandex) has this feature too.

I think such notifications is not what this ticket is about. Not just because technically in this use case favicon is replaced, not animated.

The ticket IMHO is about favicons which constantly move.

In any case, if I don't like a web site (its favicon, or the content) I don't use it; I personally don't see the anymated favicons as a serious problem and wouldn't spend any hour of my time working on it. Moreover we don't have right to demand it from FireFox team.

Although I understand the author of this post, I sometimes feel annoyed by certain features or problems in software too. Give it some time, and you will forget about it :)

That isn't really animation, they actually change the icon. The firefox bug is about setting an animated gif as a favicon.

Reddit enhancement suite has a similar setup.

And a useful one at that.

Lichess, and some messengers like telegram and whatsapp web clients.
