What type of monitor are you running at 1024x768? Is that the native resolution of that monitor (that is, if it's an LCD monitor, is it the recommended resolution) or are you using a lower resolution because you have trouble reading the screen?
Also, why do you have the google bar installed in firefox, when you already have the google search engine available from the top right (or ctrl k)?
Also also, your version of firefox is out of date. Might want to hit www.getfirefox.com to update
