Howdy all. Since the latest update to FireFox, on some webpages, the icon for FF will start blinking, and FF will slow to a crawl. It will do so until I leave the webpage. It doesn't do it on all web pages, and not on the same webpage every time. I can't find anywhere that it gives an error message, or pop-up, or anything. It just blinks and slows down until I leave the page. Any ideas??
