Reddit Expand is a free Chrome extension developed by maxplays88. It falls under the category of Browsers and is classified as an Add-ons & Tools subcategory. This extension allows users to expand Reddit posts without having to open them in a new tab.

With Reddit Expand, a small "Expand" option is added to the end of the title of a Reddit post that appears on the front page or within a subreddit. Clicking on this option opens a full preview of the post, which can then be closed by clicking on "Expand" again. The preview can be resized using the provided edge on the bottom-right corner.

While the extension generally works well, it should be noted that posts that link to websites other than Reddit may not load properly. This is because certain third-party websites do not allow previews in iframes, such as YouTube.

Overall, Reddit Expand is a useful Chrome extension that simplifies the browsing experience on Reddit by providing a convenient way to preview posts without the need for opening multiple tabs.
