New Thunderbird version 78.4 will not connect to my isp - HughesNet - and will not download or send new email. How do I fix this? Older version 68 worked just fine. I'm using Windows 7. At the suggestion of another article I checked the security settings on TB - they seem to be just fine. My address book is intact, and all the older emails downloaded also. Just can't get the new ones.

The TLS change that worked is referenced through the links provided, sorry I didn't write them down! Three or four lines above TLS version in the config editor... Something on the order of "security.TLS. ... enabled-deprecated" changed false to true.

See the articles under "see also" https://support.mozilla.org/questions/1297273 - changing the TLS setting allows me to download emails, but TB is terribly slow and hangs a lot.

Changing the TLS version to 1 got me the emails, but the whole program bogged down and made reading them an exercise in extreme frustration. Changing the the TLS from false to true seems to have fixed the issue, after restoring the TLS back to 3. Thanks.
