browser problem question

[Bosox3]

Im just bought a new macbook and im running into a problem with getting my browser to set at full screen. Firefox opens to maybe 90% full but still showing my side icons on the desktop. This might be an easy fix but im kinda clueless, this being my 1st mac and all.
I tried just clicking on the + but it only centers it.

Right now what its doing is sizing the window to the width of the web-page you're viewing, which is why it isn't going all the way to the side.

In the bottom right hand corner of the window, you should see 3 diagonal lines. if you click and drag them, it will resize the window to whatever size you want it to be.

Hope that helps

I'm presuming you mean it won't take precedence over the dock? If you set the dock to auto-hide (right-click on the separator on the dock and select 'Turn Hiding On' then try maximizing firefox, it'll go full screen.
