Bug 40202 – Web Inspector: Would like to be able to edit rules from user style sheet

• Resolution: DUPLICATE
• Component: Web Inspector

The Inspector currently doesn't let you edit rules from the user style sheet. It would be nice to be able to do this.

The USer stylesheet is mostly an anachronism; it isn't exposed as a configurable thing by any WebKit clients.

We don't allow editing User Agent style rules in the sidebar or editors. Rules in author stylesheets are fair game though.

Haha, I misspoke! I have never seen this dialog before.

I think the bigger UI problem right now is that rules jump away after you edit them, since "editing" is implemented by serializing to text and replacing an entire stylesheet. There's no persistent object model for rules; we found the CSSOM code to be too buggy and/or incomplete to use for Web Inspector.

This was fixed in 2020!
