If you tend to open many tabs, closing them when no longer needed can be a tedious task. Fortunately, you don't have to do it yourself.
Dustman is an extension that closes tabs you don't need anymore. By default it closes tabs which haven't been used in the last 20 minutes, leaving at least 5 tabs open. It ignores pinned tabs and tabs that play sound. You can restore tabs Dustman closes via the dustman button.
