[Greasemonkey] Getting script to run once the page fully loads

[Arvid Jakobsson]

Hi Ed.
May be you are doing this:

window. addEventListener('load', myFunction(), false);

instead of this

window. addEventListener('load', myFunction, false);

the former will _call_ the function "myFunction" and pass its return
value to addEventListener, while the latter will pass the function
pointer of "myFunction" to addEventListener.
