Basicly my skins in the minecraft launcher are not there, it says something about webgl that is not supported but it is

There's a problem with the skins part in the launcher. Something is happening that my skins are not charging. It put a message that says "Sorry! Your device does not support WebGL, which is required to manage skins" and the issue here is that I already tested if my computer supported this WebGL thing and it does, so I don't really understand what's happening..
