Some things to try:
* are you connecting through a proxy?
* are any of your about:config prefs that start with "security.tls." or "security.ssl3." set to a non-default value?
* do you have any add-ons installed that might be interfering?

Hi,

Thank for your feedback...

Strangely enough, when I deactivated addons (--safe-mode) or switched to another profile, nothing changed.

But I then restarted with my actual profile, and everything worked correctly...
