AnonReddit от valeriemorin

This is a simple add-on for users like me who prefer to browse old reddit anonymously (without any accounts). This add-on will remove banners trying to get you to buy premium, will remove all sorts of elements that are only used by account users (like upvoting and downvoting buttons). Post/comment scores, usernames, etc. are all still included.

It's basically like a read-only version of old reddit for people who prefer to browse without any intention of participating or creating an account.
