I just tried loading http://ruhrgebietaktuell.de/ on Firefox for Android and it appeared fine to me (comparing to your screenshot).

Also, are you saying it doesn't work on Firefox for iOS?

yes, PageSpeed module was disabled since we had complains. Please check now (I have enabled it again).

I can see the problem now. It looks like pagespeed is sending webp files, which Firefox doesn't support.

You should look into the configuration of your server and pagespeed.

Thank you. Hosting confirmed that after update of nginx, you have now version 1.9.10 with Pagespeed 1.10.33.4-beta - everything works like a charm.
