It does what it says on the tin. I haven't had any problems. My Reddit preferences are set to use the old version, but the add-on works even when I'm logged out, so it's helpful.

No longer supported by Reddit HQ.

An absolute must-have. I'm simply unable to enjoy Reddit without this add-on.

Works perfectly fine. I use it since opting out of new Reddit design does not work.

Ok

Great little addon. Uses only 980 bytes or 46 lines of javascript code.

Old reddit forever. Down with new reddit, booo

A must-have.

Simple but powerful, one of the best extensions in the entire store.
