Hi, thanks for filing! Currently, RDM lacks support for proper mobile touch gestures, which is filed at Bug 1282089. I'll have this issue block our rdm-touch project.

Marking as a duplicate of Bug 1621781. Note that since Bug 1623941 landed in Firefox Nightly 78, the user should be able to perform "drag" gestures when touch simulation is enabled. The work in Bug 1621781 ensures that a "fling" animation is registered at the end of a swipe/drag gesture (see https://bugzilla.mozilla.org/show_bug.cgi?id=1621781#c2 for more info).
