Changing your Favicon aka Address Bar Icon is super easy! There are several steps involved but none are hard!
1. Create a simple image – usually one or two colors is best – that measures no more than 16 x 16 pixels. (If you aren’t sure how big that is open Paint and draw a square, change the size (Image>Attributes) to 16×16. Edit>Select All then copy and paste that box into whatever publishing platform you’re using (Publisher, PhotoShop, or even Paint!).)
