Thunderbird Portable

[Same experience with newest versions of Portable Firefox]
Windows 10 Pro 1909 18363.1139

I have been using TB Portable for several years, successfully. Recently, with the update to v78 and up, my TB Portable installs have started to fail (on several different systems). I still have a backup version of v68 and it seems to still be working.

I have Thunderbird on two PCs, one has version 68 and the other has version 78.
I want to use PortableThunderbird, but I don't understand where I have to move the folders containing the data.

Can I keep the data folders outside the PortableApps folder and point to it with some profiles.ini?

To prevent Thunderbird from automatically updating to latest version, create a file named App/Thunderbird/distribution/profiles.json with the following content:

{
"policies": {
"DisableAppUpdate": true
}
}


When an application like firefox or thunderbird portable tells us that there is an update, if we update, it is still just as portable? Or maybe it would be better to continue installing the different versions that appear on portableapp.com?

Thanks

From a couple of hours ago I can no longer access my office email account (Gmail-based). Google sent me a message, saying that it had blocked my access, because Google considered Thunderbird portable apps “doesn't meet our security standards”.

Having routinely relied on Thunderbird portable apps for the past 20 years, this news shocked me. Did anyone experience the same? Does anyone have any advice on how to meet this challenge? Thanks.

Before I heard of Portable Thunderbird I tried -- successfully but not enough for me -- to do this myself using mainstream Thunderbird and just inputting the removable drive as the installation directory.

This was a Windows 10 Dell laptop that had had the previous installation of Thunderbird on its C: drive deleted, including ALL Mozilla/Thunderbird directories. The removable drive (D:) was an SDHC.

The new Thunderbird was 78.2.2 and the custom install settings were:

Install Location D:\Mozilla Thunderbird\
Install Maintenance Service

I have standard Thunderbird installed in the standard location on my C: drive.
I just created a fresh install of Thunderbird Portable on a thumb drive using the PortableApps app.
Before creating ANY account or profile information, I navigate to /// -> Help -> Troubleshooting Information.
I see that the Update Folder parameter is pointing to a directory in C:\ProgramData\Mozilla\updates; this is NOT portable.

Dear all,

please sorry this is the second time i post this help request just because the previouse one i deleted for my mistake.

I have Thunderbird portable on a USB Key and I used it on my linux computer ( thank to wine software layer ). I had no problem to check mail, to see all my folders on ther left folder pane, etc.

When I came back to use the USB Key on my Windows computer I discovered that all folders was disappeared.

Greets. As always, thanks for the awesome work you do here.

I have the Thunderbird Portable 32bit version. Ever since the most recent update of Thunderbird (78.2.2) I can no longer get Windows to see it as the default for opening mailto links. It defaults to:

\PortableApps\ThunderbirdPortable\App\Thunderbird64 and in so doing asks me to create a new account.
