I normally use Fedora but my Fedora machine died yesterday. For a time being I want to use Thunderbird on my Mac.

I have a backup of my thunderbird profile directory from Fedora 42. This corresponds to thunderbird-128.8.0. On the other hand, the current version on the mac is thunderbird-138.0.2.

1. Since the version number is higher on the mac I think I will be able to use the old 128.8.0 profile with the new mac version ?

2. If I do this, I will not be able to transfer my profile back to Fedora when I get it working again (because the version number there is lower) ?

3. Is there a way from me to install thunderbird-128.8.0 on the Mac so that I will be able to transfer my profile back to Fedora ?

was Windows 10 Pro, now Windows 11 Pro on replacement laptop (old one is not operational). I can't get my profile into Thunderbird because (presumably) I'd backed it up using my cloud backup service (and forgot that most of the time it's incremental), with the possibility of a straight copy from the old SSD if it's not fried.

How can I at least retrieve the data in there, (and/or convert it to a readable format) i.e. emails, that are in the Mail folder, including Local Folders? Some of that goes back to early 2000's, and some accounts that I no longer have. It's probably better to have most of that out of Thunderbird anyway, since my profile is ~99GB on disk.

Currently I have at least 7 active email accounts, and that fluctuates with .edu addresses. In the profile IMAP Mail folder, there are 20 .com account folders, a few of which are inactive or from changes, and a couple from setting up my main account just to see if that would link up with the associated files in the old profile (not). I can't tell what they all are except for those for which I'd made subfolders under the IMAP Inbox.

So since I don't only have 1-2 accounts, this is a big deal, and having to keep multiple browsers/private tabs open is not easy to work with. I'd even tried the Firefox Containers as a temporary work-around, but I'm having troubles with that.

Any help is appreciated! I can't get anything done, and the new laptop doesn't even have all that I need set up yet.

What is this file, encrypted-openpgp-passphrase.txt-11.corrupt? I have 123 of them. I think it may be created every I migrate Thunderbird from one PC to another. Is it OK to delete them? I have no use for them that I know of.
