Full screen does not hide tabs and there is no "hide toolbar" option available when I right-click.
When I attempt to full-screen a video, the address bar and the tabs remain at the top of the screen. Everyone is saying to right-click the empty space near the top of the screen and to put a check next to "Hide Toolbars," but when I right-click, nothing of the sort appears. (If helpful, what DOES appear is "Reload All Tabs, Bookmark All Tabs...., Undo Close Tab, Menu Bar, Bookmarks Toolbar, and Customize...")

Hi Krag, that right-click menu tip is for Firefox's browser full-screen feature (F11 turns it on and off), not for full screen launched from the video player.
Are you having this problem with the built-in HTML5 video player or with a plugin video player such as Flash? Usually you can identify the player by right-clicking the video: Flash shows a short menu with its name on the bottom, while the built-in player may show a long Firefox context menu or something created by the site.
