When popups come up, they often are too tall for all of them to be seen. Either the top is missing, including essential menu bars, or the bottom is missing, containing the action buttons, or both. There is no way to adjust the size of the popup, not can it be moved on the screen. Also, I just tried to follow your instructions for resetting Firefox to default because my home page has been hijacked, and the options tab only gives a popup (too big to see the top,) which only talks about history and bookmarks. There is nothing said about resetting in what I can see. What's going on?
