How to make app windows fully fit screen?

[MacNoobGuy]

hey guys, i'm still getting used to OS X after coming from Win7. i've set the dock to 'hide' and i want to make all my app windows like firefox fit the screen without me needing to manually do it. when i press the green button it doesn't expand it to the full screen and i need to manually drag it down.

how else can i do this?

thanks

Click on the two arrows pointing outwards in the top right of the window.

i don't see that in firefox or most other apps. i can stretch it manually -- i guess i'll need to settle for that.
