Hides pets, mounts, quest bosses, equipment, and backgrounds that display snakes, spiders, rats, and bees on the Habitica website (https://habitica.com/), so that players with phobias about those creatures can use the site with safety. It does not hide pet eggs or quest scrolls since those don't display clear images of the animals.

When an avatar uses one of those backgrounds, the extension hides the full avatar, not just the background. This might be improved in a future version.
