I suspect you need to install an older version of Greasemonkey, try GM 1.6
Thanks!
Chrome suck...
Firefox too ...
And Pale Moon....
:-)
there is a great mozilla addon called classicthemerestorer. highly recommend
I test "Pale Moon" as alternative to Firefox :
I have installed Greasemonkey
Greasemonkey 1.15 works for me... NOT 1.16

OR:
You need to install Guerilla Scripting instead of Greasemonkey.
And I still have not figured out Guerilla... it is lacking in too many ways... and I have given up on it. I thought I would test it for future use if Greasemonkey fails in future PaleMoon versions.

Someone is working on forking Greasemonkey for Pale Moon.
Greasemonkey 3.9.3.1 works nicely on Pale Moon 27.2.1, and there is also 3.12b6 if you are more daring.
HELP : How to install userscript directly with Pale Moon ?
I test "Pale Moon" as alternative to Firefox :
I have installed Greasemonkey but when in want install a script from Greasy fork it only show the code of it and don't offer the install popup ....
