Works, but a pain to use. Rated 1 out of 5 stars

Annoyingly, the centre of the zoom is at the corner rather than the cursor position, so you lose the part of the image you are focussed on.
Then you have to use the scroll bars, rather than a 'grab' cursor.
Does what it says, zooms (some) images, does not zoom text etc., does not zoom flash.
Sad.

So. it works, but it's a pain to use.
I'm looking elsewhere.

This review is for a previous version of the add-on (0.4.4).
