How-to Detect Greasemonkey |
pii personal information security |
|
If you are a Greasemonkey user, then you may be surprised to know that Greasemonkey is informing every page that you visit that you are a Greasemonkey user.
Since Greasemonkey is a add-on that not every Firefox user has installed, that is personally identifiable information, and a potential security risk, so that is why Scriptish was made to be completely stealth.
Anyhow, if you are curious how to detect Greasemonkey as a webdev, well here's how you do it:
if (Components.interfaces.gmIGreasemonkeyService) {
alert("I smell a monkey!");
}
<script type="text/javascript" src="resource://greasemonkey/addons4.js"></script>
<script type="text/javascript">
if (typeof GM_addonsStartup !== "undefined") {
alert("I smell a monkey!");
}
</script>
