You can disable a Chrome extension—and re-enable it if you change your mind—using the same blue slider. To find it, click the three-dot icon in the top-right corner of your Google Chrome web browser. Hover your mouse over More Tools. From the pop-up menu, select Extensions. Click the blue slider next to the extension you want to disable. If you click the Extensions button (the puzzle icon) in the top-right hand corner of your window and don’t see the extension in the drop-down list, you’re all set.
