Reddit Comment Collapser - Firefox Add-on for Comment Management
'Reddit Comment Collapser' is a free, open-source Firefox add-on. It allows users to collapse a comment and its replies on Reddit by simply clicking on the column of the desired comment. Users don’t need to get stuck in lengthy comment chains anymore - with this extension, the entire top-level comment can be collapsed by selecting the outermost column. It is only compatible with old.reddit.com and works perfectly with Reddit Enhancement Suite and subreddit themes.
