Thunderbird Portable

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.

After a reboot. when I start Thunderbirdportable 91.6 from my pinned spot on the taskbar - I check the properties map to D:\Applications\ThunderbirdPortable - it now looks to setup an email account!

It was working perfectly prior to the reboot.

How can I get my D:\Applications\ThunderbirdPortable\Data\profile loaded and why did this happen?

I recenlty upgraded manually to 91.6. Today I get a message saying would I iike to upgrade it? Am I right to say the portableapp Thunderbird version does not support auto updates like this? Should I turn off the update checker?

I recently upgraded from Thunderbird portable version 60.0.1 to 91.6, using it standalone, no platform.
I have been trying to get to see my sent emails in conversation in Thunderbird. The Thunderbird forum has been advising me via a thread I started.
It turns out there is a context menu option, "Open message in conversation"
