Why does Chrome link to "data: text / css" on all sites?

Question

While debugging the website, I found this tag under the body of the page I was debugging:

<link rel="stylesheet" type="text/css" href="data:text/css,"> 

and I thought some crazy Javascript-Error added this to my site. But I could not find anything like this in the entire source code of the project.

After checking with Firefox, I noticed that only Chrome displays this tag in Elements-, Resources- and Network-View. It does not appear in Chrome's "View Source", though.

What does it mean?

Answer 1

I tried the same weird css link and found that this was due to the AdBlockPlus (ADB) extension for Chrome that I included. When I disable this extension, the link no longer appears.
