A: 

This will be extremely tough and complex and kludgy to achieve, if it's possible at all. It would require to predict the target site's behaviour before navigating to the link. On second thought, this may in fact be possible using the onbeforeunload event but I expect a lot of trouble with pop-up blockers and the like.

I am assuming you have external links, and would like to show some "return to original site" bar in order to not lose visitors.

What I would do as a simple workaround is open the site in a new target="_blank" window in both cases, and have your "return to site" link close the window using window.close().

Yeah, I think that could be ok, but where should the "return to site" bar be visible? - in the new target="_blank" window? If so, how to do it? I know how to open a new window and how to write to it using document.write but I don't know how to combine opening that external site and writing to its source. Should I appendChild to its body with position: 'absolute' and put it on top of the site? I would appreciate some ideas.
