There's also ctrl+r and ctrl+u, if you don't like function keys, but I suppose options are good...
Thank you for post a valuable information. In my experiences, Sometimes such shortcuts are not working, because web site / web application takes key events or conflict.
So this addon is one of options. :-)
Thank you for creating this little add-on to add back Reload to the View menu! I don't know why the Firefox developers saw fit to remove it. I kept being thwarted every time my fingers typed Alt-V-R and it wasn't working anymore. Now it works again.
