Thunderbird Portable

All of a sudden, after years of use, with no alerts, I am getting anti-virus alerts on my work computer when I start/use Thunderbird portable. I would like to post a printscreen, but don't see how to do it. I also can't test the detected item because McAfee deleted it. But from the log there is this:

Hi, I'm using Mozilla Thunderbird, Portable Edition, and I was wondering if there was an option to block the software with a password so that the content of my e-mail messages does not appear without the correct password. I searched if this option exists in Mozilla Thunderbird, but dindn't find it. Does anyone know a way to protect the software with a password? I prefer open source options or free ones. Thank you.

Windows 10 64bit
ThunderbirdPortable 52.5.0 32bit

If mailto links are assigned to be opened with ThunderbirdPortable, it seems to truncate the command line arguments it sends to thunderbird.exe.
I've tested the same long mailto link, almost 1000 chars long (the raw url encoded version) with predefined body etc, with the same profile in both portable thunderbird and a normal thunderbird installation. In the normal installation (same version 52.5.0 32bit) it works just fine. I've tested the mailto link in Firefox 57, Edge and IE11, all with the same result.

I can't see images in incoming messages. However, if I forward the same message, in the drafting window I can see the graphics.
Also, when I send a text with color, in Sent I see it without color. What can be the reason?
TB 52.4 - Windows XP

As you know when users click on a "mailto:....." link on a web page the corresponding local email client is called and pre-filled with the given email address.

Unfortunately Thunderbird Portable does to register itself in Windows as a possiible mailto Handler.

So I cannot select it as a target program.

Is there a workaround for that?

Thank you

Hi

I use TBp 52.4.0 with win 10

Is it possible to add a parameter for the launcher to start the thunderbird.exe with a higher priority
like this :
cmd.exe /c start "Thunderbird" /high "D:\t\TB\ThunderbirdPortable.exe"
this will only start the thunderbirdportable.exe with the prior 'high' but not the thunderbird.exe
or with a parameter within settings.ini

thanks
kind regards

Since I want to use Thunderbird Portable from an USB flash drive the drive letter and path could change from time to time resp. computer to computer.

When I go now to Account Settings----Account---->>Server Settings
then the local directory is specified as ABSOLUTE path:

D:\tools\ThunBirdPort\Data\profile\Mail\pet345@hotmail.com

Hallo,
i need Help again...
I´d sync my Fritz.box Disk (User Doc´s and TB) with our new qnap-. NAS- Disk.
After then, if i start one of the Thunderbird´s from the Fritz.Box (NAS) Disk coming ever the ERROR
"Thunderbird is already running, but is not responding. To open a new window, you must first stop the existing Thunderbird process or restart your computer."

Assume I just installed the newest TB Portable on Win 7.
I did not define any accounts until now.

Now I have an external file samplemsg.eml which I extracted from another email client program resp. got from a Thunderbird installation on another computer.

Now I want to view the content of this samplemsg.eml email with TB Portable:

How can I do this?

Dragging it onto the TB Portable window does not help.
I miss a menu "open message file" or similar.

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.
