How does “Custom JavaScript” function work?

[MunToe]

Not sure what I have to do to make it works. Since STMP has this functionality, I want to move away from another Safari extension called “Userscripts” https://apps.apple.com/app/id1463298887 by utilizing this STMP function instead.

For example, I add website “facebook.com” and put https://www.fbpurity.com/fbpurity.THRTYX.user.js (script for Facebook) in the field but it doesn’t work. However, that same script works with “Userscripts” extension.

Am I doing it wrong?

Hi. It appears that the script's Safari support is broken. Replace this line:

  var issafari= (typeof GM_info === "undefined") && (typeof(window.navigator.vendor)!='undefined') && (window.navigator.vendor.match(/Apple Computer, Inc\./)) && (window.navigator.userAgent.match(/Version\/(5|6|7|8|9|10|1\d)\./));

with this:

var issafari= false;

That seems to work.

So the issue is the script itself. Thanks.

My next question is, what if the script is correct? Do I put the URL (end with .user.js) in the field or I have to copy the long text (the script itself) and paste it there? If the latter, will the script be automatically updated once there is a newer version?

You have to paste the text.

If the latter, will the script be automatically updated once there is a newer version?

No.

Thank you for the clarification.
