Custom Cursors -- .gif format?

I am getting much amusement from this extension! However, I am wondering what sort of compatibility it has with uploading gifs as cursors. It allows me to upload my gif files in question, however, when I choose to deploy them as my current cursor, the gif does not animate, and only remains static on the first frame of said gif. Am I doing something wrong? Or is this extension not meant to be gif-friendly when it comes to cursors?

Thanks in advance~!
