Konqueror (and other browsers, but Konqueror is the one I use) can be
instructed by websites to open pages in new windows (e.g. through the
use of target="_blank" in a hyperlink). It annoys me when websites do
this.

I would like a configuration option that instructs Konqueror to ignore
such requests, so that pages always open in the same window, unless I
(the user) explicitly request Konqueror to open them in a new tab or
window.
