This extension is completely useless. I set the page zoom to 90% in the extension for a specific page and saved it as a rule. When I close the page and reopen it, the page zoom is not set to 90% because you can see this when you check the page zoom in the Firefox hamburger menu.

Works well all sites at what ever i would like it to be

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Used to be good, but UI is outdated and doesn't work with the dark theme of Firefox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but addon is outdated,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

Awesome add-on.
Minimal permissions used - just what it needs to make it functional.

One improvement would be to allowe "per machine" zoom functions.
ie. I would like to use different zoom levels for the same website on my laptop vs my desktop machine. Then it would be perfect!

Thanks for a great add-on!

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.
