I think there could be some problem with the browser that you have installed because I have also installed the same version of browser but I am not getting any such this with my browser. Anyways first, let me know whether you have installed the beta version or anything else?
Anyways see I would like to recommend you that you should Right click a blank spot to the right of the Tab, check, Menu, Command, Favorites or Status bar, and if suppose still you are not able to do anything then you can have another option to press alt button and see whether you are getting the menu bar or not, because once you get that then you can easily select toolbar.
