Favicons are one of those things that basically every website uses but no one thinks about. When you’ve got 100 tabs open, the little icon at the start of every browser tab provides a logo for the window you’ve opened. Twitter uses the little blue bird, Gmail is a red mail icon, and Wikipedia is the bold W. It’s a convenient shorthand that lets us all navigate our impossible tab situation.
Bad news is there is no easy way around this right now until browsers maybe offer to clear this cache and give you an option not to load them or to disable favicons.
