It works for me! I don't need audio.

круто, можно даже вне браузера запись вести

It is okey to use. I don't want audio so it is okey. But if you need audio, this is not the addons you need.

It doesn't record audio. Since I was trying to record my screen just to convert it to GIF, I'm okay with that!

It works -partially- under wayland, which is a lot by itself. It allows capture of a FF window, which means it does what it says. Kudos.

Does exactly what it says. Exactly what I was looking for. Thanks.

O Simples Funciona!

It works perfect, what else :)
