The icon is invisible on my toolbar but I know where it is.

Simple, easy and very useful, many Thanks!8)

The extension is perfect. Can I ask a manual custom zoom to have a 133 % zoom (the perfect ratio for my screen) ? Thanks a lot.

Used to be good, but UI is outdated and doesn't work with the dark theme of Firefox

it does zoom,
but addon is outdated,
configuration pane has problems with visibility on firefox dark theme,
changing zoom level consumes too much time if many many tabs are open, because it changes the zoom for every tab in background also, which is unnecessary
also github repository has status archived since 2019

primarily used it because addon has lower size than other zoom addons,
so time to change addon

The best zoom addon for Firfox I personally trust. Minimalistic settings parameters that cover everything, unlike the excessively complex recommended addon for zoom. I mean for something so basic why do they want to complicate simple.

Es fantástico! sirve mucho cuando se usa Windows sin escalado de resolución ; aumentar un poco los sitios web y que se vean excelente.

Can you create this extension for other browsers?

Supporting this developer after Zoom Page WE messed up.

Very good but would love to be able to type in the zoom level I want

So far its working awesome! Super fast and very stable, I really like it!
