Reddit Comment Opener is a free Chrome add-on developed by Reece. It is designed to help users open all comment links on a subreddit page, excluding stickied threads. This handy script saves time and effort by automatically skipping threads that have already been opened within the past 24 hours.

One of the main features of Reddit Comment Opener is its ability to open all the threads on a single page simultaneously. This means that users no longer have to manually click on each individual comment link, making it a convenient tool for those who frequently browse subreddits with numerous threads.

It is worth noting that Reddit Comment Opener will only skip threads that it has previously opened, but not those that have been opened outside of the extension. Additionally, the extension may take a bit of time to finish all the web requests, as it opens the comment links all at once.

Overall, Reddit Comment Opener is a useful add-on for Chrome users who want to streamline their Reddit browsing experience and save time when opening comment links on subreddit pages.
