What file is Firefox using for userContent.css
I'd like to know if Firefox has found my css modifications. Is there a way of querying the location of the file that Firefox is using? I had a situation where Firefox didn't find my userContent.css. How would I diagnose this.
I find this code fragment around the internet. I attempted to run it, but got an error.
Components.classes["@mozilla.org/file/directory_service;1"].getService( Components.interfaces.nsIProperties).get("ProfD", Components.interfaces.nsIFile).path
I got these errors. Use of getPreventDefault() is deprecated. Use defaultPrevented instead. common-min.0cd8251fe9d4.js:4:25928 Error: Error retrieving geoip data
common-min.0cd8251fe9d4.js:10:17360

Please update to the new static version here: https://github.com/mozilla/tabzilla/" tabzilla.js:612:17 The Components object is deprecated. It will soon be removed.

You need to evaluate that code in the Browser Console to find the path to the current profile folder.
Components.classes["@mozilla.org/file/directory_service;1"].getService( Components.interfaces.nsIProperties).get("ProfD", Components.interfaces.nsIFile).path
You need to set devtools.chrome.enabled to true on the about:config page to enable the command line in the Browser Console.
Paste the JavaScript code in the command line. Press the Enter key to evaluate the JavaScript code.
The built-in Page Inspector also shows rules added via userContent.css to a website as (user agent) rules with a link to the userContent.css file.

You can use the DOM Inspector to see what rules are applied to an element. This includes rules added via userChrome.css and userContent.css.
