I like it because it is not confusing like the one that comes with Linux in that you move the magnifier with the mouse instead of moving portions of text around inside the magnifier which can cause you to lose your place. But I would change two things, which would be a wider rectangle view for reading longer line widths and fix so it wouldn't disable when scrolling down the page using the mouse wheel.

I can't answer to reviews directly, so this is in response to the last review, but there is a shortcut! I don't know why this info is only on their homepage, but the shortcut is: Alt+Shift+Z

No hotkey

Works good, and the nice part when you click or scroll it goes away.

why the heck this can't magnify over videos on youtube? I think it's showing a magnifying piece of the thumbnail instead of the video playing? odd

I wish there was an option to remove the mouse pointer from the capture area

Very nice for what it does, but I sure would prefer the option of a rectangular or square shape.

Nagyon köszönöm Szivecske (Glin), hogy ezt elkészítetted. Kiválóan működik. 💛

since the last firefox version I get a black image in google maps......

A great add-on, I would love to use it, but I am not a fan of the circular lens. The circle is an inefficient shape for maximizing screen space. The vast majority of my time using tools like this are to read long lines of text, or to magnify images/videos that by design are stored as rectangles. If there was an option to be able to set a customizable square-rectangular lens this add-on would be PERFECT! It would earn the 5 stars it deserves.

Also honorable mention to keyboard shortcuts for finely adjusting the zoom level on the fly.

AWESOME! firefox 79 ideal for me 70/7

Doesn't work on pdf viewed in firefox, which is the primary reason I downloaded it.

Super useful! really comes in handy when working with hiDPI monitors and small dimension pages.
Suggestion: can you add a one-touch option to turn on and off image-rendering: -moz-crisp-edges; on the magnifyng glass? Sometimes it's better to have the anti-aliasing off when doing pixel matching.

Did not work

Excelente, configurable el tamaño de la lupa y el zoom.

I really love the idea of this add on. I only gave it 3 stars because it's tough to read while moving the magnifying glass....hard to explain. Would be 5 stars if you could set it to be the page width and you just scrolled up and down with the mouse IE: allowing you to magnify a larger area so you could read say a paragraph at a time before moving the mouse.

Other Functionality as is is flawless thus far...nicely done!
