Eliminating frames from windows

[tomt]

On some sites i run across they insist that i enable javascript and then plaster a unmovable frame either on the top or side of a window. A good example of this is http://www.pinterest.com/Jeremyandmeg/f ... ont-yard/
basically the window at the top asking you to register is what i want to eliminate. Thanks

Does this help?

Holding the left mouse button down on an absolutely positioned page
element and hitting the DEL key will remove it (useful to forcibly kill
in-page popups when scripts are disabled)

No it does not as i need to have scripts turned on for some pages to work, Also, as a FYI, i am NOT trying to impersonate a mod, i just happen to notice my chosen name was very similar to one after i signed up.

No it does not

In that case you'll need an addon that can do custom CSS, such as Adblock Plus or Stylish.
(It's at least theoretically possible to do with surrogate scripts in NS but that's probably more complicated than this needs to be.)
