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

zooming algorithm like soap :(
pleas add option to view lens content like a Photoshop zoomed image

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.

Soooo every time I use the extension all I get is a non-transparent white circle ...

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