Why isn't it enough to just test in Chrome? Are there major differences in how browsers execute code?

Great question. The differences matter depending on your particular website or web app.

An example, here is how well browsers support the lazy load attribute for images

caniuse.com/#feat=loading-lazy-attr

(IE and Chrome support, Firefox does not as of 2/17).
