This should probably be documented at https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Experimental_features once implemented.

It's already implemented, so we should document it now I think.
Then I guess, I misunderstand the feature. What always worked for me is zooming in and out pinching two fingers on the touchpad of my Windows 10 laptop. Switching apz.allow_zooming
to true
doesn't change that behavior for me.
So could you please shortly explain what the desktop zooming does differently and how it works? That would help a lot to properly describe it on MDN.

Currently pinching on a desktop or laptop on a touchpad or touchscreen with do a "reflow zoom" where it zooms in discrete steps and things jump around. This is different from "apz" or "pinch" zoom which currently happens on mobile if you do the pinch gestures on the screen and it is a smooth operation where everything gets bigger without reflowing.
Desktop zooming is to bring this smooth type of zoom to desktop.
If you enable apz.allow_zooming on Windows you will be able to do this smooth pinch zooming if you do the pinch gestures on the touchscreen (if it exists) of your laptop. If you have a laptop with a precision touchpad then you can further enable the pref apz.windows.use_direct_manipulation and that should allow you to do the pinch gesture on your touchpad and have it do the smooth pinch zooming.
Does that all make sense?

Thank you very much for the clarification, Timothy! Unfortunately, my laptop neither has a touch screen nor a precision touchpad (but Dell Touchpad driver), so I can't test it myself right now.
I have added it under https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Experimental_features#desktop-zooming now (taking Firefox 42 as the earliest version, as that was the version that introduced the preference according to bug 1186004).

I wasn't seeing it either so I made a no-op change to the page to rebuild it and it shows up now.

Is it okay to land this with Bug 1654933 unfixed?
Are you still seeing bug 1654933? That bug should be "fixed" by bug 1655160 (ie flipping a pref so the code that regressed it is no longer active). I'm leaving the bug open to track a proper fix.

Backed out 3 changesets (Bug 1620055, Bug 1621740) for causing leaks (DManipEventHandler)

Dang, the ownership of DManipEventHandler shouldn't be too complicated. Hopefully not hard to figure out.

From the log:
WARNING: mDmManager->Deactivate() failed: file /builds/worker/checkouts/gecko/widget/windows/DirectManipulationOwner.cpp, line 659
That is why it's leaking. Not sure why it's failing though.

Thanks! I looked at the autoland push and there as another failure as well, which I've filed bug 1657102 for.

Incidentally, metrics showing that now there's a lot of zooming activity on Nightly: https://mzl.la/3iB9rCz

Looks like we have covered this appropriately on https://wiki.developer.mozilla.org/en-US/docs/Mozilla/Firefox/Experimental_features#UI
So I think the docs for this are completed for now.
