For me the same. A temporary workaround:ä use FF options - advanced - certificates - validation and deselect 'use the ocsp ...' Afterwards turn it on again. We do need new certificates. Afaik they are ordered and paid but not yet ready? Or what is the status?
Secure Connection Failed An error occurred during a connection to maemo.org. The OCSP server has no status for the certificate. (Error code: sec_error_ocsp_unknown_cert)
