It works well for me. Just click on the image and it opens the actual image file instead of that bullshit webp.

edit: actually i just noticed something, it only works when you access images from the old.reddit.com interface. It doesn't work on the standard reddit interface.

Works on my machine. Thank you for providing a way to circumvent reddit's insane default!

works as intended you just have to go into your add-on settings and enable its permissions
