Iceweasel: permissions.default.image=3 (that is, prevent third-party images from loading) is ignored for some sites?
Hi,
Am having a weird issue with iceweasel: permissions.default.image is set to 3, which means no third-party images should be loaded, yet iceweasel loads images from wikimedia.org (and possibly some other sites). Anyone else can reproduce this? Below is an html snippet I used to test the issue, I see two images, in paragraphs 1 and 3, though none should have been loaded as per permissions.default.image=3 setting. The external image in paragraph 2 is not loaded or shown, correctly.
Any ideas? Thanks
# aptitude show iceweasel
Package: iceweasel
State: installed
Automatically installed: no
Version: 38.6.1esr-1~deb7u1
Test html snippet:
<html>
<body>
<p>0. about:config property <b>permissions.default.image=3</b></p>
<hr/>
<p>1. The following image from wikimedia.org should not be loaded if permissions.default.image is set to 3 (no third-party images):</p>

<p>2. An image from pinimg.com should not be loaded as well:</p>
<p><a href="https://s-media-cache-ak0.pinimg.com/564x/77/0e/21/770e21f681a5e0267e5ce0dcdbc0ddb3.jpg";><img src="https://s-media-cache-ak0.pinimg.com/564x/77/0e/21/770e21f681a5e0267e5ce0dcdbc0ddb3.jpg"; style="max-width:100%;"></a></p>
<hr/>
<p>3. The same wikimedia.org image again:</p>
