Scrolling issues using Windows 11

Do you have a particular example site in mind that can be used to verify and inspect the behavior? Thanks.

The website below is where I first noticed this issue:

https://alliedcycleworks.com/collections/echo#build-kit

So okay, I see the site is a little more convoluted to scroll, as it's not natural document scrolling but they apparently script the scroll timeline instead to some extent. That's however quite common and pretty well supported for years so it should not give you any trouble.

Do you by any chance use some third party system mouse tools as support.mozilla.org/kb/x-mouse-button-control-firefox-110 or similar? Does the same reproduce if you restart intro Troubleshoot Mode from Help menu?

I can only imagine that some of your "privacy" addons might interfere with the sites' scripts that are also responsible in part for content scrolling, as the site in general appears to scroll just fine (trackpad, arrows, scrollbar), GIF attached:

Do you perhaps have another site as an example to look into?

I found this website, which uses scrolling, also has the same issue: https://bastioncycles.com/

These sites are all amazingly designed, well laid out, and honestly interesting to flip through — however they all seem to employ scrolling behavior based on timeline/progress and heavily relying on scripting. I tested them across versions and devices and they appear to work fine in general, but their specifics can have an impact.

There's two possibilities. Something tampers with the scripts. Use Troubleshoot Mode in Firefox to rule out any extensions, and also hardware acceleration.

Or right away the performance recommendations are causing trouble, the above will lead you there too but: Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems
