Oh dear, I'm on my phone and my finger slipped aha :]

* Is greasemonkey secure / protected from site owners running scripts with
user-script level privileges?

* Is greasemonkey secure / protected from malicious scripts sniffing
passwords and sending them off elsewhere?

* Is greasemonkey secure / protected from scripts / websites being able to
edit files on disk (within the script folder / within the firefox profile /
other user folder items / protected operating system files)?

* Is greasemonkey secure / protected from other people with physical/remote
access to your system and can they install scripts without your knowledge?
-> Can they hide/obscure the presence of any scripts?

* Is greasemonkey secure / protected from other addons or other
programs/addons/Firefox bugs etc?

* Will gm interfere with other programs/addons/firefox instances or
profiles?

I could probably continue for quite a while longer and still not list
everything, but hopefully it helps jump-start you on your way to defining
what you mean when you say "secure".

If it is still a blanket far-reaching answer that you want, I'm going to say
no. Before anyone starts panicking, I refer you back to my trust model - I'm
not saying that greasemonkey is vulnerable, I'm just saying that despite not
knowing of any specific attacks* (though as a non-dev this doesn't
necessarily count for much), I can't guarantee that it is safe so I'm not
prepared to declare otherwise. All it takes is a single new exploit to
appear to make something proveably insecure, but it is nigh on impossible to
prove something secure with the budget of a free open-source project (or
even a billion dollar project for that matter - just take a look at
Microsoft, Sony, Adobe and the American intelligence services** for just a
few examples!)

Anyhow, must stop myself here before I miss my stop - please don't take any
offence at anything I've said, I just get a little worked up at when
'security' is so naively oversimplified like this (and when the devs don't
know much better, but with such a broad topic you can't expect everyone to
know everything.. but that is a rant for another night :] ).

Kind regards,
kwah

* other than malicious scripts and unauthorised access to your system, of
which I don't believe neither are issues that Greasemonkey should / can
reasonably protect you from. I don't mind sharing the reasoning behind this
if you want, which basically boils down to trust.

** Research Gary McKinnon and Wikileaks for starters..

Only if you can't read English. The other add-on developers I've queried
have answered this same question with a yes or a no.
If you can't answer no,  then the answer must be yes. I like greasemonkey,
but I like the truth more.
