A few weeks ago after an automatic update I ended up having Thunderbird version 131.0.1 installed, I have no idea how this happened. On opening I get a message telling me I shouldn't be using a beta version and that I should revert to the latest general release version (128.4)

Today when I had some free time I downloaded 128.4 and installed it. On opening it it says that I can't use a profile file from a later version with the earlier version. Is there a way to recover from this WITHOUT having to set up the whole profile again from scratch.

Meanwhile I have done a system restore so I am back with 131.0.1 It has not given me any problems so far. Is there a new general release version imminent that will get me back on track?

I would appreciate any help I am not a computer expert, just a user, and find Thunderbird a very good email client.

I have two older, Win7 laptops running TBird Supernova. Both are failing the update check. I think it's because some internet security protocols are misconfigured. Does anyone know what protocols (TLS etc) TBird's update routine is looking for?

HELP! This new version installed today, and Thunderbird suddenly stopped running and no longer runs. I get the message: "A newer version of Thunderbird may have made changes to your profile which are no longer compatible with this older version. Use this profile only with that newer version, or create a new profile for this installation of Thunderbird. Creating a new profile requires setting up your accounts, calendars and add-ons again."

The message seems erroneous because it is running the newest version. Should I step back a version? If so, how do I do that?

Thanks!

Was "accidently" upgraded to beta version 133.0. How do I get back to stable version? And why did this happen?

I am supposed to be on the esr release program, but today I was automatically updated to beta release 133.0. This is the second time this happened. Thunderbird shows a red screen, and recommends I install the last stable release, 128.5.0esr, which is what I want to do. But the last time, when I tried to go back to a stable release, it then wouldn't let me do that because it says the profile may no longer be compatible. I solved it painfully using timemachine backups of older profiles.

What is the simplest, safest way to downgrade, now that I am in this situation? And why is this happening?

Thanks for your help!
