T'Bird Portable New Version Updates don't seem to work and also takes extreme amount of time on USB flash drive - SOLVED

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:


can't read old emails (Tbird portable not finding my profile)

Submitted by bangbang on March 22, 2023 - 5:50pm

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?

Keep getting notifications for 102.8.0 update even though I'm already running this version.

Submitted by joetron2030 on March 14, 2023 - 12:02pm

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.

[Bug] Favorite folders not saved when moving to new PC

Submitted by Alexander230 on March 2, 2023 - 6:23am

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.

Problem with migration from Enigmail (TB 68 to 78)

Submitted by Elsee on January 31, 2023 - 10:18pm

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.

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:

Disable SplashScreen for ThunderbirdPortable via the INI file

Submitted by AbsolutelyRandom on November 6, 2022 - 2:19pm

Is it safe to simply create an INI file named ThunderbirdPortable.ini, place it next to ThunderbirdPortable.exe and include just one line:
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.
