To set an icon (called a Favicon) to show on a browser tabs:
Click "Settings" tab, in the left menu.
In "General Settings", scroll down to "Website Favicon", then choose an image.
Note: The best size for a browser favicon is 16 x 16 pixels. If using Canva.com to create your favicon, you can create the image as 100 x 100 pixels. That size works too!
Refresh your browser a couple times to view the favicon.
