Thunderbird Portable

Topic title is the concise summary, I apologize for such a long post below to add more details.

I'd already posted a topic on Thunderbird's primary forum and was referred here. Here's a link to that topic but all info in it is reposted here on this Portableapps topic:

Tried every option found - can change menus, composition fonts, increase points - nothing works! Latin, others - nothing! Did not do anything to provoke this sudden change and must use a magnifying glass icon for every incoming message - please help, thanks.

Hello
I'm running Tbird portable on a usb drive with Windows. It was working fine until recently - but now when I open it, it asks me to create a new profile & I can't figure out how to direct it back to the original profile (I've tried the -profile "path" command line argument but I still get the same request to create a profile) - how can I get it to access my old emails again?
Thanks!

Has anyone else started getting spurious new update notifications for 102.8.0 even though they're already running this version?

I'm not sure if this is a general Thunderbird problem or something specific to the portable version. I'm leaning towards it being an issue with Thunderbird itself but wanted some advice before I open a ticket with Mozilla.

Thanks in advance.

There is a bug that strongly breaks usability: when I move Thunderbird Portable to another PC, it doesn't remember which folders has "Favorite" mark. Also, I have "Favorite" option set in View - Folders menu, but it resets to "All" on another PC. Some folders occasionally lost Favorite mark even when I move Thunderbird folder within 1 PC.

Hello, I am asking for help with Enigmail migration. I guess the legacy version 78 is required to port the keys from Enigmail to the new PGP format. But I can't find this version anywhere. If I take version 91 directly and try to import my private key, I get an error message even though the key is correct.

The download hash does not match for the German version of

Expected according to the list (GERMAN)

Is this the correct forums to post this question? I've also posted it under General Forums --General Discussion

I've been running Thunderbird Portable Edition from a USB flash drive for about three years. Today, when I tried to start the app, I received the following error message text box:
-----------------------------------------------------------------------------------
Mozilla Thunderbird Portable Edition | PortableApps.com X

Is it safe to simply create an INI file named ThunderbirdPortable.ini, place it next to ThunderbirdPortable.exe and include just one line:
DisableSplashScreen=true
Or maybe it is required to copy the whole content of ThunderbirdPortable.ini from "Other\Source"? I would like to know what I'm doing so I don't ruin the app's portability.

I have stored all files on a Stick and connected it to my Android-Smartphone via a Micro-USB.
A Describtion advices to start the Portable with the ".exe".
But this doesn't work on my Smartphone.
Is there anywhere an APP to start an ".exe" ?
Is there any other way ?

Thanks für ideas or solutions
