I am pretty certain that you did not use the latest dev build but instead an older one. As you posted the download URL as version number, i so far cannot prove it. So first, please FOR ALL YOUR REPORTS learn how to find the version number of your Adblock Plus installation (See "Other Notes:" section in test description) and second of all ensure to get the latest version at least daily.

Okay, after reproducing this myself, I found that IE 8 still shows the buggy behaviour, while IE 11 after works well.

The trouble is that the style sheet is blocked. The ACCEPT header in IE8 is */*, so we cannot derive mime type from it and we should try to fallback to use URL, which is

The path is /zz/combo (see WBPassthruSink::GetContentTypeFromURL) and it does not contain anything about CSS, it seems the server script which glues specified CSS in query string into one.

If we cannot detect the content type from path then we could try with the query string. Although I'm not sure whether it makes sense to analyze query string of the URL because

  • for the site makers it's very easy to modify it
  • we can wrongly interpret it

Split it into parameters and find let's say the first parameter which has some known extension, like ccs, js, swf. What do you think?

One may check the code here
