I am new to Mozilla...when I bring up a new web page on my laptop, the left 3 inches of my site are white...and the last three inches are white. The toolbars extend from side to side...So it looks like a margin issue. However, when I use IE, the website goes from the edge of the left edge of the laptop computer to the right edge, as it should be. Now, here is another curiosity, when I log on to my IGoogle site, from Mozilla, the site is presented properly...meaning, all the way from the left to the right extremes of the laptop. CTRL + and CTRL - increases the font size, but it inside the website presentation with 3 inch margins
