Thunderbird Portable

I posted this to the Thunderbird forum thinking it is probably a Thunderbird issue. They suggested I post here, so here goes. I've had Thunderbird installed as a "Portable" application on my Thinkpad X1 (6th gen), Windows 10 Pro machine for over a year (installed on 06 Sep 2018). Profile resides on a network location. Never had a problem with Thunderbird updates until I noticed an issue today (it looks like the last update, v60.9.1, was on 07 Nov 2019). The update presently fails for an "unknown reason". I've tried the suggestions in another Thunderbird post multiple times but no luck.

Can't download Beta, Version 71.0 Beta 4 for Windows, English
https://portableapps.com/apps/internet/thunderbird_portable/test

Try to download and returns error:

The requested URL /portableapps/ThunderbirdPortableTest/ThunderbirdPortableTest_71.0_Beta_4_English.paf.exe was not found on this server.

I think it should be Beta 1 ???

When I first installed the portable in 2016 importing worked. Now I cannot import any keys using the Key Management of Enigmail. I do not get any error or anything, just nothing happens. I generated keys through Kleopatra on my desktop and use the keys with no problem. I cannot even import older keys. Is it normal for everything in the Thunderbird folder to have the security of "Read Only"? I can go thru the motions to remove that but it always goes right back. Going on vacation soon and have my portable apps on a thumbdrive and I want to use that for all my needs.

Hello everybody,

can someone please tell me why the thunderbird version here is 60.9.1 and on the other hand version 68.2.2 is available at the offical Mozilla-Website ??

I just installed ThunderbirdPortable. But if I change the path to ThunderbirdPortable,
the Lightning calendear is not any longer available. However, this was the idea of a
portable application, that I can move it anywhre and continue working, am I right? So
what is the problem here? I have no more idea.

I've had no problems with Microsoft accounts nearly all year and gmail accounts are fine, but Microsoft accounts keep asking for password. I've tried removing accounts and re-adding them, but still no resolution.
Please help!

I am using TB portable v 60.8.0. I do a lot of traveling and have TB on a USB stick. We have 5 people in the office and everyone has their own calendar using TB and I can see all 5 calendars on my machine. All off the calendars are google calendars.

I am using TB Portable (60.9.0) on a computer that runs Windows 10.
The main reason I use a portable version is that I don't have admin privileges to install any software on the machine.

I would like to set Thunderbird as default mail client (i.e. when clicking email links I would like to directly use Thunderbird for composing a new message).

Unfortunately all solutions that I found here and more in general online suggest to: (1) install a non-portable Thunderbird version, so that that can be set as default mail client; or (2) change the Windows registry.

I would be thankful if anyone could help me out and tell me how to disable the splash screen for the Thunderbird Portable 2nd Profile App.

Neither exists a corresponding ini-file in the directory "Other\Source" nor does using such a file in the conventional suggested way work.

Hi everybody,

i have set up two thunderbird profiles, one that’s used by me (profile 1) and the other one used by my girlfriend (profile 2).

I take care of all programs and keep them up to date in our household. Unfortunately, when I install addons, do improvements, adjustments or fixes to thunderbird for profile 1 I have to do the same (often fiddly and pesky) process for profile 2 so that both thunderbird profiles benefit from my changes and stay on the same level.
