Reload All! is no longer in the addons.mozilla.org (AMO) Sandbox and is now approved for use by public.
I submitted it to Mozilla AMO for public nomination. And after a week long wait, I got a mail from them in which they said they have accepted its current version.
I plan to make some further changes to this plugin.
I am planning to add configurable shortcut keys, as I mentioned in the previous mail. And I’ll move the Context Menu Item for choosing the selection tool from the navigation area to the tab area.
