1220139 - Firefox DOM Inspector doesn't show :visited pseudo-class

Status: RESOLVED DUPLICATE of bug 713106

(DevTools :: Inspector, defect)

Description

[João Lopes]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:43.0) Gecko/20100101 Firefox/43.0
Build ID: 20151022004116

Steps to reproduce:

Created a website that makes use of :visited CSS pseudo class to change the color of a link. The CSS for the visited link is applied correctly on the page but I wanted to change its style in the DOM inspector.


Actual results:

When inspecting the element, the styles for a:visited are not shown. When I try to add a new style using the a:visited selector, it stays gray as if the selector didn't apply to the element, but the rules will apply.


Expected results:

The rules for :visited should have been shown in the rules list and new styles added to this element should be marked as matching the selected anchor element.

I assume that Firefox kind of "locked itself out" of being able to probe the :visited status of links when that feature was nerfed for privacy reasons (https://developer.mozilla.org/en-US/docs/Web/CSS/Privacy_and_the_:visited_selector).

Thank you for the report, your assumption about Firefox locking itself out is right, see bug 713106 comment 0.
