I’ve saved the DxO-Forum-Link in my firefox as a favourite. When I try to open this favourite-link or writing the link https://forum.dxo.com/ directly in the adress-line I got this message (in german):
App kann nicht geladen werden
Sieht so aus als wärst du offline! Bitte überprüfe deine Netzwerkverbindung und probiere es nochmal.
When I first open the old DxO-forum http://forum.dxo.com/index.php and than choose the favourite-link of the new forum all is right.
Do you have an idea what’s on there in my browser?
Seems it’s not a general problem: this behaviour exists only on one of my computers. Sorry for panic!
