I don't like GreaseMonkey's data collection policy. Short of forking it myself, what are the options for a non-invasive Firefox extension to implement user scripting?


  • Source code available
  • Gratis
  • No data collection from my computers whatsoever


  • Compatibility with existing GreaseMonkey user scripts

    Scratch that. I have forked and fixed the scripts: github.com/Hunter-Github/greasemonkey It works for me, can probably close this question. Feb 23, 2015 at 11:14

    On SE sites, it's perfectly fine to answer your own question :) Just a pity it won't be long until we no longer can use extensions without Mozilla's own blessings (signing)...

    Have you looked at Scriptish? It's a fork of Greasemonkey as well. Not sure what data is collected there (I wasn't even aware that Greasemonkey collects something).

    Does Greasemonkey still collect data even if you've unchecked 'submit anonymous usage statistics' in its options? Mar 26, 2015 at 14:44

I was in a hurry and couldn't bear waiting, so I took the logical step and forked the 'Monkey: https://github.com/Hunter-Github/greasemonkey.


  • fits my own requirements


  • took about half an hour, so wasn't exactly gratis
  • I didn't put the .xpi package online, thus not accessible on Windows
  • "I didn't put the .xpi package online, thus not accessible on Windows" - out of curiosity, why? Mar 4, 2015 at 12:52

    @Mawg - it isn't easy for a layman to verify that the .xpi file corresponds to the source before installation. I may not be trustworthy: ) Mar 4, 2015 at 13:57
