scrolling vs pages

dudes,

i noticed that on chrome the access to search results
is made with pages, you type in the page u wanna go to
in order to see that page's results.

however no firefox the access is still with infinite scrolling,
no pages there.

my frfx version is 31.

could you look into that?
i presume it should be the same on any browser.

p.s.: i also sent a mail to contact@ etc.

thanx.
