I don't know why in Linux and windows they is huge zoom difference I use both Ubuntu and windows. I have also noted this with Chrome. Both on windows, and Linux they were on 100% zoom. Is this a bug or adjustment according to OS as I am used to Linux I feel it difficult.

You can just take a picture of Google.com from both Linux, and windows you will find difference in zoom while comparing them.

Zoom is relative; it is on top of the default scaling.

If you are handy with the web console, or if you load my test page (https://www.jeffersonscher.com/res/resolution.php), you can check the window.devicePixelRatio property that summarizes the effective zoom ratio compared with a base size of 96 pixels per inch. For example, with page zoom at 100%:

  • 1 => system scaling is 100%
  • 1.25 => system scaling is 125%
  • 1.5 => system scaling is 150%

The system scaling can be overridden by setting the layout.css.devPixelsPerPx preference. The default value of -1 simply follows the system scaling. Positive values set a new base level of scaling.

To avoid pulling of hair and gnashing of teeth, try not to enter a value lower than 1.0 (or on a Retina display, a value lower than 2.0). If a calamity occurs, zoom as much as you can and click the reset button at the right end of the row to return to the default.
