adds a context menu to delete sign-up/sign-in overlays that prevent you from viewing a page
F*ck overlays is a VERY light extension to give you an option to delete anything on a webpage whenever you want. F*ck overlays does not remember anything you have f*cked, so simply REFRESHING the page should cause the element to reappear.
Right click on an element you want to delete (usually overlays, but works with other things too).
In the context menu, click "f*ck it".
Sometimes you might need to f*ck multiple elements to get rid of an overlay. In the future, f*ck overlays may be expanded to support permanent deletion of elements.
