Galaxy S4 web browsing help

I upgraded from a Galaxy S1 to an S4 recently, and one of the frustrating changes was the interface when typing stuff in text fields on messageboards. On my old phone, if I held the phone sideways in landscape view, I got plenty of sieve to see what I was typing, and it would automatically scroll down as I filled the screen with text.

On my new phone, the keyboard takes up 3/4 of the screen in landscape mode, and if I type more than a few lines it will not scroll down to let me see what I’m typing. This is really frustrating and I dont know where in the phones settings I can tweak this. Any ideas?

I don’t know about the stock keyboard, but worst case there are plenty of replacement keyboards that let you choose from many different layouts and options. Thumb Keyboard is one I use on my Android.
