Rated 4 out of 5 stars
This is a great add-on for those of us who are blind as bats. Still, I have 2 suggestions.
1. The global zooming level should be more accessible. Ideally, it would be on the same menu that pops out when the status bar icon is clicked (even if that means said menu has to be re-conceptualized as something other than the site settings).
2. The zoom level should go over 300%. Ideally, I would want to use this add-on to view pages from a natural sitting posture, but I find that even at maximum the letters are too small for this purpose. This might not be a problem for others with better visions, but for some of us it is quite troubling.
Still, thank you very much for your awesome program!
