A URL is a web address, so it's hard to answer your question without more information. If you are trying to get back to a page or site that you were on before, have you tried looking at History? In any tab, if you tap the address bar, Firefox for Android will display one of the following lists, and you can swipe left or right to switch between them: * Recent Tabs * History * Top Sites * Bookmarks * Reading List Does that help in getting where you need to go?
