Plucky is a self-control oriented filter that can: 1. block all images and videos from some or all websites 2. block access to some or all websites during certain hours of the day 3. enforce a user-configured waiting period on changes to Plucky settings Note that Plucky Lite (this extension) only affects the browser (for example, Chrome). If you find that useful, fantastic! If you want more extensive filtering, you may want to try the standard version of Plucky after taking this extension for a whirl, because the standard version of Plucky will affect your whole computer, not just the browser.
