I like the address bar icon instead of the toolbar icon.

Very useful Addon, I use it frequently to save articles I like, but have an ugly layout.

One feature I would really like to have is the option to format everything to justified text.

There are some features in design mode that don't seem to work - an explaining tooltip would be helpful (or did I miss the description somewhere?):
The crossed-out T seems to toggle Bold/Italic mode, but I can do that with the B and I buttons as well.
The picture symbol does not seem to do anything at all?
The quote-symbol seems to do the same as the text-indentation, except you cannot undo it.

And finally, I'm missing the 'options'-page, as shown in the video, is this feature not available any more?

I never use the text-to-speech function so I cannot say anything about it.

Every thing is fine about it but narrator should be doing the same as Firefox's narrator dose . It should follow speech every time . If possible can you develop it that way it will be very helpful to all

Nice work. I love the ability to adjust the background (and other) colours. It may be useful to clarify that such 'overrides' go into the bottommost sections of the CSS block in options.

I seem to be seeing one bug though. Win7/SP1/x64 FF64. When closing the 'reader view' and going back to normal, it often returns me to the wrong page: not the one I was reading (normally and in reader), but the previous one. It's as if it was occasionally performing the "Go back one page" operation. This happens quite frequently, perhaps 30-50% of the time.

It would also be great if the original scroll position of the page could be preserved (the built-in version does this), but that's relatively minor.

Thank you!
