I don't see any of the problems described above or in the current responses to you when I try it with Chrome. One click of back brings me back to HN, and I only get one item in the history list.

With Safari, one click brings me back, but I do see one entry per "page" added to my history menu.

Firefox behave the same as Safari

I have no add-ins or extensions on Safari other than 1Password. On Chrome I have 1Password and a viewer for chess games in PGN. I have 1Password and Firebug and a PGN chess viewer in Firefox.

I wonder if you have some kind of extension or something that the site does not get alone with?

I'm on a Mac.
