Back to Top 3.2.1

Back to Top is a Firefox extension that helps you navigate long pages. Basically, it adds two items to the context menu (right click), the "Go" menu, and the toolbar.
The items do just what you would expect. "Back to top" scrolls the current window to the beginning of the document and "Go to bottom" scrolls to the last line of the document.
All browsers come stock with "Back" and "Forward" buttons to display previously viewed pages. These are very common, basic navigation needs. Going to the top or bottom of a page is also an everyday browser necessity. The scroll bar works just fine for this purpose but can be time consuming and error prone when viewing very long pages.
This extension allows for this functionality with a single mouse click. Of course, the same thing can be accomplished using keyboard shortcuts but the object here is to make it mouse accessible.
Version 3.2 adds new functions to the icons. (See table below.) Now you can eliminate one of the icons without losing any functionality. More valuable toolbar real estate is conserved!
Version restrictions:
- Will not work on pure flash pages, "about: xxx" pages, drop down form selection fields, and possibly some xml pages.
