To edit settings in the Chrome web browser,
1) Click on the three vertical dots, or the "shishkebob", on the top right of the browser.
Notice that from this menu you can easily open your Bookmarks, open an Incognito window, view your History, among many other tasks. If you click "More Tools" you can add Extensions.
2) Select Settings.
If you see an orange exclamation point rather than the three vertical dots, it's just a message about an extension. You can click on the message to accept permissions.
