I relied heavily on the zoom-in/zoom-out feature which I easily located by right-clicking. It's no longer there nor all the options that came with it. I'm going to have to remove colorzilla (again, have already removed, reinstalled, restarted browser, hoping it would restore the program). I'll have to go shopping for alternative programs but I'll check in time to time and see if this once awesome program has been restored to its former glory.
