Hi Republic1777, could you check the following settings:
(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful or accepting the risk.
(2) In the search box above the list, type or paste TLS. and pause while the list is filtered
(3) If any security.tls. preferences are bolded and "modified", double-click > Reset them to restore the default value
(4) In the search box above the list, type or paste SSL3 and pause while the list is filtered
(5) If any security.ssl3. preferences are bolded and "modified", double-click > Reset them to restore the default value
Note: these are not widely used and can be disabled as a workaround for servers that have not been updated to avoid the Logjam vulnerability:
- security.ssl3.dhe_rsa_aes_128_sha => false
- security.ssl3.dhe_rsa_aes_256_sha => false
If you updated anything, does that improve the situation?
