Implementation notes:

Some proxies and middleware boxes improperly handle the TLS 1.3 protocol handshake causing an insecure downgrade to TLS 1.2. With our recent update of NSS, Pale Moon no longer allows this kind of protocol downgrade when trying to establish a TLS 1.3 connection to a server. The resulting error is ssl_error_rx_malformed_server_hello with an inability to connect to the server. To enable users to still connect to the servers or devices in question, we've added an option to switch off the downgrade sentinel. To switch it off as a temporary workaround, set security.tls.hello_downgrade_check to false.
If copy and paste operations to/from the browser are performed, Pale Moon writes clipboard contents to disk in a temporary cache file if the copy/paste amount is particularly large, to avoid using large amounts of memory to hold this data. The average paste/clipboard size doesn't tend to hit this limit in which case it is just held in memory.
Previously, these cache files, while in the O.S. temporary file location (%TEMP% or /tmp), would not be consistently cleaned up, potentially causing privacy issues if persisted. This was changed to using auto-cleaning anonymous temp files, improving user privacy and relying less on the O.S. or user performing cleanup of temporary file storage. Thanks to Sandra for pointing this out and providing the patch.
