With the 109.0 Firefox Release zooming with Ctrl + mouse wheel is disabled by default:
“On macOS, Ctrl or Cmd + trackpad or mouse wheel now scrolls the page instead of zooming. This avoids accidental zooming and matches the behavior of other web browsers on macOS.”
As I’m a little bit visually impaired, this is my most used feature in the browser (and every other program that supports this action)
In this article I show you how you can re-enable this feature.
To revert to the previous behavior (zoom in/zoom up),
* Type “about:config” into the URL bar
* Click “Accept the Risk and Continue”
* Enter “mousewheel.with_meta.action” into the search bar
* Click the edit button
* Set the value to 3.
