Ctrl or Cmd + trackpad or mouse wheel on Firefox 109 (macOS)

Anonymous
Not applicable

The Firefox 109 Release Notes inform us that:

>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.

To revert to the previous behavior (zoom in/zoom up), users need to go to about:config and set mousewheel.with_meta.action to 3.

Most users don't read the release notes, know about about:config, or even join support forums. This change should've been applied only to new profiles.

For anyone stumbling across this thread who needs more help with changing the setting, here's the article on using about:config: https://support.mozilla.org/kb/about-config-editor-firefox

Have there been cases where changes to default preference values are only effective in new profiles? Or to put that another way, are there cases where existing profiles are customized during an update to preserve old default preference values? The currently effective default value of a non-customized preference isn't written to the prefs.js file; it is inherited from the program files. So preserving an old default would seem to involve checking whether the user has customized the preference and, if not, manually creating a custom preference set to the old default, and then manually recording that this has been done so it doesn't get repeated at every update (otherwise, the user would not be able to switch to the new default).

Seconded, had to find out the hard way. It's a super useful feature too, and as I Firefox user, I'd rather have consistency on Firefox accross OS than accross browser on Mac.

I now understand why Firefox users are decreasing!

One of the main features that's missing on Safari. Can't live without that. Thanks for the solution!

This change affected my existing profile.  Over two weeks of frustration before searches finally brought me to this thread.

Considering that this makes the action of a scrolling with a modifier key the same as scrolling without it, I'm not sure that this is helpful unless this was known to cause significant confusion for new users.

I am nonetheless grateful that the option to change the behavior remains.

It was super hard to find that 1) this change happened (I thought I was going crazy!) 2) how to change it back (What an absolutely arcane way to revert back to old functionality).

If you are gonna change behavior in a breaking way, at least offer a better way to teach people who to revert to the way they liked it.

This change has been extremely frustrating for me, I thought I was going crazy until I stumbled over this post.

Terrible choice to change the Firefox default behavior in this case in my opinion, at the very least this should be in the actual settings, not hidden in about:config. And just to be clear, this is a terrible on Apple's part too.

GREEEAAATTT!  😞  Another update, another feature taken away.

This feature isn't the default behavior anymore, but it wasn't taken away. You just have to follow the provided instructions: open about:config and set mousewheel.with_meta.action to 3.

This feels stupid. My guess is more people would want firefox to be consistent across OSes instead compared to other browsers.

Just why?!

I cannot understand why a developer would make it default for this feature to be disabled when it is so convenient and useful

Furthermore to do this without any prompt. I have wasted an hour today figuring out how to get it back. I have questioned my sanity over it, but I was sure something wasn't right when it didn't work. It is something I have become accustomed to doing automatically (Using the CMD key+ scroll to zoom in/ out)
