It helps you to zoom easily in and out a web page. Thanks to the slider and the zoom buttons. It's the number one and best magnifying browser extension to customize the zoom value of that web page.

Zoom is a lightweight and useful add-in designed to get a perfect zoom experience.

A few great features in this browser extension:
+ Zoom with a slider
The best way to zoom perfectly in on a web page is to use a slider. You can change the zoom factor from 1 to 400.

+ Scroll and Zoom
When you click on the Z button and scroll up or down with your mouse. Zoom will automatically change LIVE that web page.

+ Zoom all together In/Out
If you enable this option on the Zoom options page, it will zoom in/out on all the open web pages.

+ Save website Zoom value
This saves automatically the current zoom value of this website. So when you come later back to that website, it restores the zoom value since you left the site.
As a user, you can always set it back to default zoom, by clicking on the "Reset" button.

+ Zoom Engine
You as a user can choose what zoom engine you want to use. You can use the default browser zoom engine or the CSS website style zoom. That's smoother and enjoyable.
Or you even can choose the "font-size" engine, this will increase or decrease only the text on that website.

+ Manage all the Zoom for each website (domain and web page level)
On the options page, you can easily edit or remove the zoom value of that website.

+ Option to display the Zoom value percent number in the Z button as a badge

+ Option to display the right-click menu with the necessary zoom percentages

+ Option to hold your mouse click and scroll to zoom in or out the current page

+ Set default zoom ratio and zoom step

+ Video and the web
This is one of the important browser extension also to improve your video entertainment. It zooms in the web page but it increases also the size of the video player example on YouTube™ and HTML5 video. And you can use the most popular Turn Off the Lights extension to dims the part around the video player.

+ An accessibility option to see a larger popup window
+ Magnify glass in circle and square with adaptable zoom level from 1x to 10x

Project Information:

Windows: CTRL and + or CTRL and -
Mac: cmd and + or CTRL and -
Is doing the same action as in this browser extension. But this extension helps you to increase/decrease the zoom to a custom percentage in a better user experience.

idea seems great but functionality of the user interface makes it counter productive or less efficient. Looking forward to future updates

Updated Review on Version 2.7

Oddly when I installed the MacOS 11.3 developer beta Zoom was again installable - I have no idea why. It is now working quite well and very valuable for more fine tuning of some web sites than the more limited zoom levels in Safari.

Doesn't Work on my MacBook Pro running Big Sur
