Extensity is an extension manager for Chrome that allows you to easily list, enable, & disable extensions installed in Chrome. The main reason to manage and optimize your Chrome extensions is to reduce the amount of memory Chrome uses. As you open more browser windows and more tabs, this memory consumption will increase. To resolve this, we can use Extensity to only enable extensions when we need them and disable all the rest. This way you can create a profile for web development or infosec that contain different groups of enabled/disabled extensions and switch between them as necessary.
