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. – Deer Hunter Feb 23 '15 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)... – Izzy Feb 23 '15 at 14:00

    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). – Izzy Feb 23 '15 at 14:02

    Does Greasemonkey still collect data even if you've unchecked 'submit anonymous usage statistics' in its options? – galacticninja Mar 26 '15 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? – Mawg says reinstate Monica Mar 4 '15 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: ) – Deer Hunter Mar 4 '15 at 13:57
