Really bad, quality control at Google has gone absolutely to hell lately, sad to see this from the most reputable company world wide for most of my life. This really needs a real history, actually showing the pages we've loaded through, not just providing a new search for things we searched previously. Also really need an 'are you sure' prompt before closing active pages for a new instance of opening the search, so often I lose progress on a form or completely lose track of page I reached.
