434137 - Stylesheet blocked by content policies is displayed as parsing error in XHTML

Status: RESOLVED WORKSFORME

(Core :: XML, defect)

Description

[Wladimir Palant]

Steps to reproduce:

1. Install Adblock Plus from https://addons.mozilla.org/en-US/firefox/addon/1865
2. Press Ctrl+Shift+E to open Adblock Plus preferences, click "Add filter", enter "http://static.iwiw.net/common/css/1024.css" in the text field and press OK.
3. Go to http://iwiw.hu/pages/user/login.jsp (XHTML)

With Firefox 3 (tested in Gecko/2008051506 Minefield/3.0pre) you will see a message "parsing error" pointing to the line where this stylesheet is included in the page. Note that images or scripts blocked by content policies don't trigger a parsing error.

Expected result: page should be displayed despite the stylesheet being blocked (as happens in Firefox 2).

I can not test this issue due to the site "http://static.iwiw.net/common/css/1024.css" not being active. If this issue still occurs, could you provide me with other links? If not, could you please close this issue.

I found a website where content is still being served as application/xhtml+xml - no, blocking stylesheets no longer produces parsing errors (Firefox 45).
