Touch event support on GTK3 requires APZ, which in turns requires e10s. e10s is not yet on by default in Firefox 46.
I believe e10s can be turned on in 46 release by going to about:config and adding a pref named "browser.tabs.remote.force-enable", with the value set to true. However, please be aware that this is not a supported configuration.
