hello dear

In previous versions of your software as an option (Use TLS 1.0) existed, but the new version does not have this option.

How can tick off this option?

Please guide.

Chosen solution

Current Firefox no longer have a user interface setting to disable TLS or SSL3, but you can make the change on the about:config page.
SSL3 and TLS 1.0 are enabled by default in the current Firefox release.
You can set the security.tls.version.min and security.tls.version.max prefs to 0 to disable TLS (0 means SSL3)

You may need to close and restart Firefox after changing these prefs.

  • security.tls.version.min = 0
  • security.tls.version.max = 0
0 means SSL 3.0, 1 means TLS 1.0, 2 means TLS 1.1, etc.
