Adding a Javascript script to WordPress

One of the fustrating things about ie 7 and 8 is they no longer allow program to open a wep page in full screen mode. Hence when ever I open my ie browser I have to manually maximize the screen. Is it possible to include a simple javascript routine into WordPress to automatically open it in full screen mode either through a plugin or something. The script only has a few lines of code and has been tested on most of the major browsers including safari for the pc.
