In this video, we learn how to clear Firefox location bar and browsing history. To get rid of an individual one, use your keyboard to go to the one you don't want. Then, press shift+delete and that one will be deleted. To remove them all, go to tools then click on "clear private data". Check the box of the browsing history, then click on the button to clear all the data. If you still have items in the list on your browser, then that means you have those websites bookmarked. To remove those, you need to install a "Hide unvisited" add-on to Firefox, then you will have all your browsing history deleted, including bookmarks.
