Normally, when I bookmark a page, the bookmark 'star' on the address bar changes from white to blue, which is a visible indication that the page is now bookmarked. Without it there is no visible indication that the page is now bookmarked.

Unfortunately I accidentally removed it by right clicking on it where it was on the right-hand side of the address bar. I've looked through your help and support section and cannot find a way to get it back. I have also noted that several other people have done the same thing and cannot find out how to restore it.
