I think Ubuntu has the right behavior, similar to how you can scroll windows in OS X (with the scroll wheel) even if they're not in a focus; a huge usability improvement over Windows when doing side-by-side document editing.
If anything, I believe the user agent should never change platform behavior. If platform A has behavior X and platform B has behavior Y, then the user agent should behave as X on A and B on Y. Which is to say: scroll bars should never change focus, regardless of the case (as far as I know all platforms follow this convention) Étienne On 2012-11-01 7:08 PM, "Robert O'Callahan" <rob...@ocallahan.org> wrote: > It would be trivial to change Gecko so that clicking on scrollbars never > moves focus.
