Complete fail. I was looking for a FF version of the excellent Chrome extension 'Just Read', but didn't find one. This was one of only two readers available for FF.

Cons:

• no keyboard shortcut
• no images
• nested pages––had to click on the inner page to be able to scroll
• even clicking on the icon didn't restore view––had to reload page
• basic simple text

Chrome 'Just Read':

• keyboard shortcut activates AND deactivates extension
• images included
• single page that scrolls without having to click on it
• easy-to-read formatted text
