Open userContent.css in style editor

[morat]

Is there a trick to open the userContent.css file in the style editor? I want to live debug the file.

Style Editor doesn't list userContent.css
http://bugzilla.mozilla.org/show_bug.cgi?id=1470780

I don't follow aminomancer's comment in the bug.

The style editor isn't available in the browser content toolbox.

I tried opening the userContent.css file in the style editor in the browser toolbox while on about:config and on the test page. That file isn't listed.

I tried clicking a dummy rule userContent.css link in the inspector tab while on the test page. That link doesn't open the userContent.css file.

Code: Select all

/* Firefox userContent.css */

:root { --cowabunga: rgb(0, 0, 0); }

You are probably aware of this (inconclusive) thread on reddit: https://www.reddit.com/r/FirefoxCSS/com ... tcss_live/

Thanks.

I got a dummy rule userContent.css link in the inspector tab to open the userContent.css file.

That link didn't open the userContent.css file in Firefox 87. Now it does in Firefox 88.
