Occasionally, when entering Panorama, no tab has the focus. This seems to happen most often when entering Panorama for the first time. When this happens, the mouse is the only way to select a tab.
Note that this is fixed in bug 600665. I hope to land that patch after Fx4, although there's probably considerable bit rot.
I believe patch for bug 597980 should fix this.
