If update is not possible for some reason you may try the following
Go to to Tools & Settings > TLS versions and ciphers management.
Note: If the option TLS versions and ciphers management is missing in Tools & Settings, install the SSL! It extension.
Under the TLS versions and ciphers by Mozilla section, click [change] (or Enable).
Select the Intermediate (recommended) cipher suite and click Change and Sync.
