# Vote on Reddit post or comment

Automatically vote on Reddit post or comment on reddit.com. Up, down, or clear your vote on a Reddit post or comment by its URL/permalink. Safe to repeat: it only changes the vote if it isn't already in the requested state. You cannot downvote or clear the vote on your own post, since Reddit forces the author's upvote and the change reverts on reload. Runs only via the browser extension, not the hosted cloud browser.
