Thunderbird Portable

I have just launched Thunderbird and can see this: https://i.imgur.com/2lqeMQl.png.
In settings I have it switched to: "Check for updates, but let me choose whether to install them".
Shouldn't update feature be totally disabled for portable application? I suspect an inexperienced user may launch auto-updates which in result will ruin portability of app.

The folder pane is broken after upgrading from TB 91.7.0 to TB 91.8.0.

The folder pane is still broken after fresh installing TB 91.8.0.

There is a workaround in the thread. Maybe helpful to someone else.

Phoenity Icons 3.4
Thunderbird Portable 91.8.0 with 2 Google IMAP accounts
Windows 10 Pro 20H2 32-bit

I have multiple MBOX files that are exported from the Thunderbird account. Is there a solution to view the content of that MBOX file on the system?

Neither of these two procedures work at all!

Hello,
has the latest TB protable app color themes / mode (including gray) in windows 64bit?
Thanks

Hello,
works app MozBackup for thunderbird portable and Xtraxtor for all portable email clients? I just need to transfer the whole clasic TB to the TB portable app at once.
Thanks.

Hello,
please for the exact answer where exactly you need to place these signature certificates (personal QCA+QC CA) in the portable app TB, so the app would also work on a foreign PC when connecting a USB drive, or even through a cloud e.g. terabox.com...? https://www.postsignum.cz/files/navody/thunderbird/index.html
In the classic app TB, we had them automatically installed in the windows PC repository.

Hello,
how much is this bit version of TB???

THX!

PS:
I now have 64bit windows 8.1pro. The PC informs that the TB portable is installed on a portable USB HDD as a 32bit...!

As I please quickly, simply import all thunderbird content (all different accounts, data) into thunderbird portableapps as well as mail (originally stored or also from backup archive files) from other e-mail clients in OS windows 8.1pro 64bit...? I have the complete stored (cca 53GB) contents of directories, Thunderbird files in a portable USB HDD. Unfortunately, I don't get to the original Thunderbird profile, which was in the laptop because it's destroyed, so there was no backup total file created in that old app profile, nor did individual emails be stored in the files.

Afternoon...

I am running T'Bird 68.xx (I think - I don't want to view "About" because I don't want to upgrade)

This is my dilemma...I would like to change my server settings to be prepared for the May 30th deadline for OAuth2 authentication, but I can't view account settings on any of my 3 Gmail accounts.

All I can view is a small dialogue box with the name of the account (my email address) and "account actions", nothing else.

I fear that if I can't get to the full menu of settings, I will loose everything come May 30th.
