Sophrosyne is a Chrome extension developed by jschantz4 that aims to fully block distracting media content, including downloads. This free program falls under the category of Browsers and is specifically classified as an Add-ons & Tools subcategory.

The main function of Sophrosyne is to remove all image and video content from every webpage you visit. This helps to eliminate distractions and create a more focused browsing experience. However, the extension takes a unique approach by allowing users to selectively add websites to a whitelist. When a site is on the whitelist, images and videos are visible on that particular site.

It's worth noting that Sophrosyne acknowledges the limitations of technology in accurately identifying and blocking specific content. As a result, the extension relies on a whitelist approach, where users manually add sites to allow media content. Additionally, there is a 24-hour cooldown period before a site is actually added to the whitelist, with pending sites listed in yellow for easy identification.
