OK with the new firefox 4.0 mockups rolling in a new look for firefox it has made me think....
with the new computers these days and the resolutions of most peoples monitors where is most of your browser space at we know its vertical space that its lacking in since you can scroll down pages its usually ok but what if browsers made vertical space maximum and put information onto the side since alot of people have adopted a fixed width to keep content the same on 90% of peoples different monitor sizes.
here is my quick mockup cutting and pasting with one of the firefox 4.0 mockup pics
this is not my best work but was meant to give an example and get feedback
if i get some positive feedback i might consider making a good looking mockup
