Firefox 8 seems to perpetuate the errors of the previous version plus add its own new problems. I just upgraded to Firefox 8 on Windows 7 Home Premium. The bookmark menu (which some idiot decided to try and hide) turns black when I scroll down through my bookmarks. Some bookmarks turn back to grey as the mouse cursor moves over them (like when I stop scrolling), but they turn black again as soon as I scroll. This is not unlike the previous version's behaviour of highlighting all of the bookmarks as the mouse cursor rolled over them. How about getting some standard libraries that work?
