1. Copy and paste chrome://extensions into the navigation bar in Chrome or use the menu button (the three vertical dots) at the top right corner of Chrome to access the More tools > Extensions option.
2. Next to the extension you want to manage, either uncheck the Enabled box to disable the Chrome extension or click the trash button to remove it. The icon for disabled extensions that are still installed turns black and white, and they can be re-enabled in the future.
