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

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

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

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

5/5

AWESOME! firefox 79 ideal for me 70/7

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.

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

a simple light tool. Im using many years many addons. First time i find the exact tool i needed so much cause it does what it says without complicate setup.
And an idea. If its possible make also a square shape of the tool. Much better for reading i think

Neat!!!

is it possible to have a rectangular shape on the magnifier as I would like to use it to read lines of text? nice app :)
非常好的扩展，建议增加自定义启动快捷键。而不是shiift+alt+z

just what i been looking for. :)

Problem with white non-transparent circle may not be due to extension. I had the same problem with a number of extensions until I was alerted to this Firefox setting:

privacy.resistFingerprinting

Apparently a known bug with this means white boxes can appear for some graphic items if it is not set to false.

Thank you for a really useful add-on that works very well!
