Since my website ( is configured to http2, users using FF ESR cannot access anymore. They just see a blank screen.

Other browsers and "normal" FF are working fine.

I seems to stay in connection with the cipher Suite.

User could workarround by changing "aes_256" in the about:config view.

But I need a solution for the backend to avoid loosing users, trying to reach the site e.g. via Google Search.

Any ideas are greatly apreciated

Cheers from Germany

Blank page confirmed using ESR 45.7.0

Site opens properly using Win IE.

I called for more help.

I have to disable security.ssl3.ecdhe_rsa_aes_128_gcm_sha256 (false) to make Firefox open the page, so you would have to disable this cipher suites on the server to make it work in Firefox 45 ESR.

Tools -> Page Info -> Secrity shows:

Connection Encrypted (TLS_RSA_WITH_AES_256_CBC_SHA, 256 bit keys, TLS 1.2)
