Adjust scroll amount with zoom

[batata]

When zooming in a page scrolling with mouse wheel becomes way to fast, and on the opposite when zooming out it's painfully slow.

I think we should divide the scroll amount by the zoom to have a consistent scrolling speed, if per default it's set to 5 lines, when zooming at 200% it should be 2.5 lines and when zooming at 50% it should be 10 lines.

Simple.

• Was anything done about it? I seriously need this configuration, otherwise I simply can't work with firefox!

A couple of clarifying questions for folks experiencing this:

• Are you using reflowing zoom (e.g. Ctrl+Plus or Ctrl+scrollwheel), or pinch zoom (pinch gesture on trackpad or touchscreen)?
• What OS are you using?

Personally I'm on Windows using Ctrl+scrollwheel for zooming but in case it wasn't clear enough the idea is not about changing the zooming behavior but rather the scrolling behavior when zoom is not 100%, so the controls used to zoom should have no incidence.

To rephrase my original post differently, in the current state of things one wheel tick will scroll 5 lines which represent ~100 pixels when zoom is set to 100% and ~200 pixels when zoom is 200%.
I think it would be better if the amount scrolling pixels was always the same no matter what the zoom level is.

Thanks for the added details. I understand the request, and I can confirm that I see the same behaviour. I filed https://bugzilla.mozilla.org/show_bug.cgi?id=1857656 to track a potential change to this behaviour.
