Reddit Reader – Read, Post and Vote on Stories
Reddit reader is an open-source browser extension that displays articles from a specified subreddit. You can read, post and vote on stories. And this extension displays the latest articles from the subreddits you have added, and allows you to view them all, along with their number of comments and upvotes.
You can also change your profile and your settings. To do that, go to Preferences (this icon appears when you have a reader icon displayed).
You can have it open in your current page, which makes it useful when reading another site.
