Comment 26 for bug 1697122

Is there any possibility of enabling this soon? Out-of-the-box Firefox is unusable with touchscreens, and as touchscreens become more common (e.g. I just upgraded my laptop to one that has a touchscreen), having this enabled quickly becomes quite important for a large number of users. Also, https://bugzilla.mozilla.org/show_bug.cgi?id=1182700 was just fixed in Kwin, and AFAIK that was the last blocker of this bug.

Also, AFAIK, Fedora enables MOZ_USE_XINPUT2 by default for these reasons, so apparently it's not too buggy :P
