After sitting idle for awhile, a running Thunderbird App freezes on MacOS Mojave.

I believe this started only after upgrading to Mojave. Thunderbird runs fine for awhile, then come back to the App after an hour or two of idle and the App is nearly frozen. It will eventually respond to a few clicks and then the UI responds eventually but out of sequence to clicks. The only work around is to quit the App and relaunch it. I've reinstalled it a few times.

What version of Thunderbird are you running? And what add-ons?

No extensions. It seemed to be broken for most of 60.* including 60.4 running on Mojave. It got fixed in 65.0 Beta. However, it "may" have broken again on 65.0Beta2. Will verify.
