The Firefox 10 released and I got it installed on Windows 7 computer. I thought that it is a bug-free browser but I was wrong. When the first time I launched this browser I have noticed that it still flickers before it opens. I had the noticed the same problem in previous version. Now also it still flickers two or three times. The problem is only with Windows 7 but not noticed in Windows XP. It usually happens when I open Firefox from the Taskbar.
