If you are like me, you likely have a TON of extensions and add-ons in your Google Chrome. They can really help a ton! But they also use up your battery life and slow down your computer. Ugh! That is where Extensity comes in handy because it lets you turn your add-ons off/on as needed. I do see the humor of adding an extension to manage your extensions, but it has already been helpful to speed up my computer. Basically, it adds in an icon to your Chrome broswer that lets you see all of the extensions and apps that you have in your profile and then turn them on/off from there.
It's super slick! I highly recommend checking it out if you haven't already. Let me know what you think!
