I used to use a windows XP, and I used to always use the f11 keyboard shortcut to change my current internet explorer window to fullscreen. However, now that I am using a Windows 7 laptop, that shortcut no longer seems to do anything. It might be because I now use Firefox (it seems to work a lot faster) if the shortcut was Internet-explorer specific. I do not know if it is possible for this to be the case. I am not very computer savvy .
If you have any sort of solution, please let me know! Thank you
