Thunderbird Portable

I have a backup copy from June of a TB portable installation I recently lost. I installed PortableApps, including TB portable, afresh from a download on Sep. 14. 2022 on a USB stick. It would be great to transfer all the account information, passwords, etc., plus a history of e-mails from the last 10 years. What has happened since June is still in my IMAP account and will hopefully be available after reconnection.

I am using Thunderbird Portable as stand-alone installed on hard disk.

For years I have updated on the Help/About Mozilla Thunderbird page. Today I noticed that I was on version 91.1.x and the button said [Update to 91.1.y]. The thing is that I knew the current version was v102, meaning that the updater on the "About Mozilla Thunderbird" page was not working, or was only offering to update to a minor version that was still months out of date.

Windows 10 Pro 32 bit (all updates), Thunderbird portable 102.1.2 (updated and also new clean install.).

I created a new Gmail-account (pop3) whose messages are saved in the global inbox; this setting is saved. I check the mails manually.
Now I want this account to be included when manually fetching messages, and checked the corresponding box in the server settings/advanced of the account:

Tools / Account Settings / ACCOUNT NAME / Server Settings / Advanced / "Include this server when getting new mail".

Is Thunderbird 102.1.0 the stable version?
When I tried downloading the Windows version of a reliable site
(gratissoftware.nl)
they had a message saying that version 91.1.12 is stable
and I better wait dwnlding 102.1.0 until all (possible) errors are solved

Hi, today I just download the latest portable Thunderbird version 102, and I make a install which overwrite my old Thunderbird portable 8x.x (I can't remember the version now, as I just overwrite the old installation folder)

When I try to start the new installed Thunderbird portable, the main window shown up, and I see the left Folder is empty.

Hi,

I have multiple profiles running in multiple instances of thunderbird at same time.

Each version of thunderbird portable has updated
ThunderbirdPortable.ini
with changes as below
AdditionalParameters= -no-remote

I have setup multiple copies of PortableApps

How do I return to a viable version without losing data? Update of working ThunderbirdPortable gave "error:platform version 91.11.0 is not compatible with minVersion>=91.10.0 maxVersion

Hallo
Due to a stupid mistake with robocopy, my Thunderbird portable (56.??), which I had been using for a long time (30K mails), including backups, was deleted.
With Recover software I was able to recover the "profile" folder and an infinite number of caches, among other things. I can't say whether all files are complete
How do I get TBP running again?
Preferably with all settings, etc., if not then I'm also satisfied with the access (import) of the complete mails.

Gmail server is not accepting my PW anymore, I guess due to new policy restricting less secure apps. After fiddling with their instructions to manage apps that are absent from my account, I'm about to give up on gmail altogether rather than fiddling with t-bird. My version 58.2, works fine (except slow startup) and I don't like updating to avoid unwanted changes.

Any simple solution before I cancel my 20-year old gmail account?

Thank you
