i'll vote for firefox
because most modern browsers allow you to have multiple tabs open, but a true web surfer like you might have 20+ tabs open. In Chrome the size of the tabs decrease with each new tab that you open, until you can no longer differentiate between two tabs. Firefox handles tabs in a bit of a different way: instead of tabs getting smaller, Firefox has tab scrolling. This allows you to easily read which tab is which instead of guessing.
