## Review summary

Users highly valued YCS - YouTube Comment Search for its ability to swiftly search YouTube comments, which was fundamental to their viewing experience. However, the add-on has recently stopped working, no longer loading comments and appearing abandoned with no updates from the developer. Multiple users note that the extension causes freezes in Firefox and exhibits trust issues due to unclear licensing and missing source code. While it worked reliably for years, many have been forced to seek alternatives or hope for a fix, with some recommending a continuation version called 'ycs-continued.'
