The best plug-ins are the plugins or addons or extensions which BLOCK or REMOVE superfluous functionality.

For example, plug-ins which BLOCK advertisements, popups, cross track site trackers, cookies, annoyances, “notifications”, comments, social media, etc.

Also, the best technology REMOVES NOISE or distractions. My love for noise cancelling things like BOSE noise cancelling headphones, AirPods Pro noise cancelling, moving into a quiet home and neighborhood, door sealing to seal out noise, noise dampening material, silent cars (electric).
