I zoomed in on a page (amazon) now I can not zoom out. Need help please

Yesterday I wanted to read the small print on a label so I zoomed (on an Amazon Page) in

I guess now the computer decided that I want that zoom always. So even after 24 hrs I visit Amazon (after quiting FF and restarting the computer) the page is unmanagably HUGE.

1) I tried Option+COmmand, -

2) Tried Trackpad zooming.

Neither worked.

Any suggestions other than never visit Amazon from the Macbook Pro

Thanks
