Thunderbird Portable

By default normal (non-portable) Thunderbird has a default profile folder.

Where is this profile folder located in the Portable Thunderbird installation?

Assume I want to define now a second, own profile folder inside a Portable Thunderbird installation folder like

D:\tools\PortThunderbird\myprofile123\

How can I achieve this?

When I call the ProfileManager for the normal, non-portable Thunderbird then the PM creates a "redirect" file "profiles.ini" with the location of the actual new profile.

I just tried to upgrade to ThunderbirdPortable_52.4.0_English and at end of upgrade got BSOD (blue screen of death). Downloaded and reinstalled same software. The install went OK but when I started TB - same result. Backed out by downloading and installing ThunderbirdPortable_52.3.0_English and all was back to normal. Anyone else seen this issue?

I have a 7 to 8 accounts and all their settings created on the portable apps version of Thunderbird on a USB. I am wanting to move that data to my Desktop PC (new machine) where I've installed a fresh copy of Thunderbird. The new machine doesn't seem to detect that data.

Shouldn't it if the USB is connected to the same PC?

just installed Thunderbird Portable Version: 55.0b2 (32-bit) onto a 32GB memory stick. Set it up fine on my desktop pc, all working. Put stick in another pc, run thunderbird.exe from stick and up comes a new installation, not my emails and email accounts. How do I make it truly portable and pick up my emails from any pc using my stick. Help would be appreciated, thanks. Mike. ps. running Windows 10 on both computers.

Opened Thunderbird Portable at work this morning, per usual, and was asked by Thunderbird if I wanted to create a new e-mail account. I did not, as I was perfectly happy with the 4 I already have. Or, had, as all of my accounts have disappeared. They were most certainly there yesterday! I cannot see anything wrong with the profile folder, and I ran a CHKDSK on the drive and no errors were reported.

This is a two-part error, and I'm starting with the last part.

I got this error popup window upon starting TB Portable:

45.8.0 for Windows can not run (run) Thunderbird. The app
Failed at start giving the following error:

Hi all,

My Thunderbird Calendar no longer want to sync with my online google calendar. For now I have used the Google Calendar plugin but I would prefer to get the original one working.

The location of the calendar is googleapi://email_address/?calendar=email_address/name

I'm assuming this is still acceptable?

Hello,
I have a few questions about my "Thunderbird Portable":
*
I have for my wife and me respectively copies on a Fritz!Box connected hard disk (NAS).
Since a Thunderbird update from 14.x.x to 45.4, the start takes up to 10 minutes and often crashes.
In addition, the address book is no longer visible in the view.

Hey,

I have some serious issues with FF, TB and several other Apps over PortableApps!

I own three different PC (Windows 10 64bit as User/AntiVirGear-N10, Windows 7 64bit as AntiVirGaming/AntiVirGamingT7 and Windows 7 64bit as User/AntiVirGear-N7) and all my data and apps are on a 1TB HDD without any errors (weekly SMART check, file defragmentation and chkdsk) and here is the point: It happens randomly!

Let me show you some scenarios and define N10 as A, T7 as B and N7 as C!
