What is Mozilla Thunderbird ESR (Extended Support Release) Version?
The new ESR version of Thunderbird email client software will provide more stability to its users as it’ll receive yearly major version upgrade. Users who don’t want extra new feature additions regularly and want a rock solid email client program to access their Mail Inbox, will definitely like the new ESR version.

Since new version 128.1.0 under Windows 10 22H2 build 19045.4651, every time I send a new message, Thunderbird freezes for a few seconds and the hourglass icon appears. If I switch to a different window, a different program there is running & responding just fine. About 10 seconds or so later, Thunderbird comes back, and if I switch to it, everything works fine (until the next time I send a message).
This only started happening after I got upgraded to version 128.1.0.The message does get sent and is received by the recipient(s), so it’s mainly an annoying error, not a critical one.
^^ Might be a bug in the new version. You can roll back to 115 stable version or wait for the next release.

May I point out that the above is not true of the Thunderbird snap.
I run Thunderbird snap on Ubuntu 22.04 and a couple of weeks ago it was automatically upgraded from 115 to 128.0esr version and has just this morning been automatically upgraded to 128.1.0esr version.
I’ve been using Thunderbird for years. One of the most useful extensions was Xpunge, which no longer works in TB-128.1Oesr. How does 128.1Oser handle the trash, junk and spam? I hope your answer is that a feature like Xpunge is built in.
