Address Bar and Bookmarks bar are broken

I can type in the address bar, but the search box is just showing a magnifying glass and can't be clicked on. None of the tools at the right hand side of the address bar are present, so no star for bookmarks etc... If I type an address in the address bar and hit return/enter, nothing happens at all. My bookmarks bar is completely blank. (I can still access bookmarks via the hamburger menu though) Everything was fine yesterday, any ideas please?
