The nav bar is broken for the first page opened in a tab: load page 1, load page 2 Now try going back to page 1 - it's impossible because the back button is still greyed out. Load a third page and the button wakes up, but I still can't go back to page 1, just 2 - it also will not appear in the drop down history (right click back button) This simple flaw makes your browser a massive pain in the backside to use right now.
