• This is a security and maintenance update, updating the platform code to Pale Moon 27.2.1.
• Please see Pale Moon's release notes for details on the updates involved.
• Important note: If you have previously changed the configuration to enable deprecated/vulnerable cipher suites to connect to old mail servers (you really should upgrade those where possible; e-mail by design is private so secure encryption is very important!) then you will most likely need an additional step:
• In Options, go to Advanced, open the Config Editor, find security.tls.insecure_fallback_hosts and add your insecure host(s) to it (comma-separated). This is needed for RC4 and 3DES.
