Is there some recent change in webpages or web browsers that is creating more and more places on a page where a pop-up appears when the mouse cursor hovers over a spot?
Lately (the past few months) there is an infestation of pop-ups that appear on web pages (using Firefox). I don't pay particular attention to where the mouse cursor is when I'm reading something on a page and I find this trend irritating. For example, on Wikipedia pages, I get pop-ups that are supposed to be helpful notes when the pointer hovers over a link. I don't want this feature and it only starting happening recently.
