It does not work for me. No button show up. I think that it did not work with Greasemonkey 4.0 but I have switched to Tampermonkey and it does not work with that either.
This is regarding script version 0.0.1.20160521101909 on Windows 10, Firefox 64-bit and Tampermonkey 4.5.5.5633.
Does not work on Firefox 57
