I am using Firefox on my 27" IMac as the default browser, and it works well. I need it to default to a more zoomed in setting. I know I can zoom in using "Command +", but I am compelled to do this after every screen. How can I change the default screen setting for a larger display of Firefox every time, consistent with the large and fine pixeled display at 2560x1440? I am using Firefox 7.0, Mac OSX 10.7.1, on a mid 2010 27" IMac with an I7 cpu and 16Gb of RAM. Thanks!
