I have started from console with "LANG=C firefox" and went to one of the https addresses (eg. https://debianforum.de/ ) . Insteed getting an error, I get the certificate warning as expected for the non-trusted certificate in english. That workaround works for me. Thanks Maciej for your information about the ticket #429835.
One sideeffect does this hack have. After closing all firefox', the language will be kept english insteed german in my case, but ok.
