XPCOMViewer on Firefox 3 Beta 2During a weekend I worked on XPCOMViewer and I tested it on Mozilla Firefox 3 Beta 2. I was really suprised when I’ve noticed that Firefox 3 supports the <grippy> element – see the screenshot (<grippy> element is highlighted by the red box).

Another new UI element which I’ve noticed is resizable splitter between URL bar and search bar – it’s look really nice:
