1527002 - Display the correct font-size in the rule-view when it's overridden by user preferences

Status: NEW

(DevTools :: Inspector: Rules, enhancement, P3)

Description

[Patrick Brosset <:pbro>]

Steps:

• Go the Firefox preferences.
• In the language and appearance advanced dialog window, there's a way to prevent websites from applying their own font sizes, and to define one that suits you better instead.
• So do that.
• Open a tab on any website.
• Open the inspector and select an element with text from that page.

The font-size displayed in the Rules view is the one coming from the CSS served by this website's server. Not the one you defined just now in about:preferences.

It would be good to show when this font-size is overridden like that. We could check if the preference is set and at least warn the user.

See bug 1527028 for the same issue, but involving colors.
