Thank you very much, it works. Could you tell me  how to add
some more external links. I tried:

-* +www.depression.de/* +www.oberbergkliniken.de/*[] +*.gif
+*.jpn +*.png +*.css +*.js
-* +www.depression.de/* +www.kompetenznetz-depression.de/*[]
+*.gif +*.jpn +*.png +*.css +*.js

With this version, none of the external links work.
