I was adding a favicon to my site, but infortunately I decided to make an animated one. Then I deleted it to change it for something more subtle but at least in my browser it goes on blinking nervously. Does the browser memorize the favicon? Or do I have to bother all my visitors with this blinking thing forever? Why doesn't it change when I delete it and put the other one?
How long has it been since
How long has it been since you made the change? It can take a little while for the browser to take effect of favicon tweaks. I'm not entirely sure if there's a way to get instant results, someone here is likely to know if there is, but from my experience it doesn't always appear straight away.
Firefox loves to cache them,
Firefox loves to cache them, and I guess IE remembers a bookmarked page's favicon until, I think, the page is re-bookmarked (or something weird like that). Be assured that if you checked in a browser that hasn't visited your page, it should show the new favicon.
