This add-on did not work w/4.0, the only button that worked for "Options" was the cancel button. When I did split and put a window to the right, I clicked on the reload button and the window disappeared.
My mistake, thought I had checked it on FF4. In the mean time I set compatibility back on 0.8.8. It should be OK with FF3*
