Yes, in the "Update" section I addressed that. But still Home and End aren't available.

Edit: The comment below mentions another way to achieve Home/End features in FF.

Are they not? I use Cmd+Up and Cmd+Down to scroll to the top and bottom of a page, respectively, on Firefox.

You're right, I just used them and it works. Weird how Mozilla didn't mention it on the link I provided.

They do, but it might be confusing because they list "Home" and "End" first, before the Cmd+Up/Down alternatives.
