Rated 4 out of 5 stars

There is a conflict with hot-key "Ctrl + Shift + M"... same combination also used Responsive Design View on Fx 23.
But otherwise is a good add-on.

Please put style rules in chrome://magnifier/skin/ Rated 4 out of 5 stars

Please put style rules in chrome://magnifier/skin/magnifier.css.
The style rules directly applied to the content cannot be easily overridden by a theme.

I think there is actually no need for that. I use all the devtools classes to style the panel. I will try to move a little remaining things to css in next update.

Good concept, terrible execution Rated 2 out of 5 stars

Crashed right almost immediately, and is unusably slow

This review is for a previous version of the add-on (0.5). 

You are the first one to report such issue. Can you provide more information ?
Maybe you have the view gridlines enabled. It is a firefox regression which causes canvas to be slow when those gridlines are enabled.

Added extra star Rated 4 out of 5 stars

Very nice add-on, but a bit bulky in appearance. A smaller magnified area box with thinner boarders would be nice. Perhaps an interface that looks like a magnifying glass that turns the magnification up or down by scrolling the mouse wheel. Also more precise control over the level or power of magnification. (e.g. 1 to1.1, 1 to 1.25, 1 to 1.5, 1 to 1.75, 1 to 2.0 and so on) Then at 2x it could increase in whole numbers. Currently even at the lowest magnification it tends to give a boxed in feel only able to read a single word or part of a word at a time. Needs some tweaks, but it's still a nice and much needed add-on in Firefox.

I do understand. i meant to give 4 stars the first time around, but ended up with three. My apologies. A simple accidental mouse click and I hadn't even noticed until you pointed out I gave it only 3. I edited my review and set it to 4 stars.Of course as you can surely understand with the add-on in it's current state I can't in good conscience give it 5 stars. 5 stars and a 'stellar' review will come when the changes discussed are implemented.
I look forward to the upcoming changes and then spreading knowledge of this add-on's existence.
Even without the changes thank you for your efforts in making an add-on of any kind.

I think all your points are fulfilled now :)

Rated 5 out of 5 stars

Still needs some tweaking. But 5 stars for an add-on that FireFox should of had integrated a long time ago.
