Mozilla's Robert Strong has published a blog post which calls out a subtle yet significant change in recent Firefox 4 beta builds. Firefox will now automatically pin itself to the Windows 7 taskbar if you set it as your default browser during installation.
Strong finds it odd that Windows 7 doesn't do this automatically. After all, Microsoft does pin Internet Explorer to the taskbar -- except, of course, on Windows 7 N builds where IE isn't included. He's not happy about having to implement the change in Firefox, either. He posts, "It kind of pisses me off that it was considered important enough to have a browser front and center pinned to the task bar on Win7 but it wasn't considered important enough to do this for the browser that the users of Win7 have explicitly chosen to use."
