@MrAlex94 commented somewhere on Reddit that it was planned to enable WebExtensions Experiments in Waterfox 68. And they WERE enabled in 68.0a1.
But they are not available in 68.0a2.
I fixed it locally by adding this line to my mozconfig customisations -
ac_add_options "MOZ_ALLOW_LEGACY_EXTENSIONS=1"
