As followup to my problem: I uninstalled Firefox & reloaded but it came up with the same side-tab problem so I still can't use Firefox.

The side-tab experiment in test pilot made my pages come up in a 1" square in upper left corner; the rest of the page is gray & blank. I uninstalled Firefox & reinstalled it hoping it would install without Test Pilot but it reinstalled with the same side-tab issue so I can't use Firefox.
