Perfect. Thank you

Gesturefyなど他にもマウスジェスチャーアドオン等を使っていると干渉する。他のマウスジェスチャーを操作した後にも右クリックが維持されているようでホイールさせるだけで拡大縮小される。解除するために1度右クリックを入れる必要があるので・・・不便。

I especially like the zoom steps feature.

100 to 300 perfect!

Functions well. This should be a standard feature. Can't do without it!

This extension caused numerous issues with both of my computers running two distros of Linux both Debian and Arch.. on 4 different desktop environments literally crashing the desktops. Had to go into about:config files in order to completely remove it... even after removing them from the addon page this extension continued to reek havoc and remain in firefox, seamonkey, waterfox, and cyberfox... it also caused multiple problems with any chromium based browser as well including chromium, chrome, opera, and vivaldi.. P.O.S

not working with 57.0.2

It works OK in v57, but with the right side button enabled, every time it is released, the right click menu comes up, which makes it difficult to use. If this can be fixed it will be very good and highly usable.

EDIT: Thanks for fixing this issue so quickly - uprated to 5 stars!

For other users that may think it isn't working, note that although not prompted, I had to restart Firefox after installing, AND after changing settings.

Dont work on FF Quantum 57.03 - 64 bit

it is really a pity

Exactly what I needed !

Thank you very much for this. I missed my Mousezoom addon for the old firefox and in desperate search I came up empty until now. Thank you again.
