Browser tabs I actually find OK, I didn't even really consider them as "using" title bar space, since each tab is a title bar and contains no "active" areas that prevent the simple 'click and drag' action.
This does become more problematic when there are so many tabs they become tiny and the whole title bar of the browser is taken up by tabs so that there's no dead-space to drag the entire browser window to another screen. I try to keep minimal contexts (due to personal brain capacity issues), so I don't run up against this very often - I manage links that I want to keep and go back to using other means, or if I forget them then they weren't very important in the first place.
