I did something to the firefox home page and now I can only get half a page. I tried to grab a corner and drag it down to a full page, but it won't go any further. I also tried to maximize the page but nothing. When I look at my screen about 1/3 of the lower screen is a blank gray . When I move the curser to the bottom of the screen my task bar appears just as it always has. One third of GT is missing as well. I can only see about 8 postings at a time. Any ideas???
