Thunderbird Portable

for some reason the download always fails.
I manually downloaded the paf (because I gave up on the automatic update after a week of trying) from: https://sourceforge.net/projects/portableapps/files/Mozilla%20Thunderbir...
and i'm getting an error that it can not be executed.
i'm using windows 10 64bit

I think it was an update around mid August that broke my current TB Portable copy on an external HDD.
When I logged in it tried to start everything off as a full newbie - no existing profile, emails, etc.
After some research I tried starting the app with a "-profile but that didn't work.

Greetings.
I plan to migrate from Outlook Express, Thunderbird is one of the candidates.
My computer is old, OS XP, and I format it with frequency, then a portable software would be very convenient.
The problem is that I just download the portable Thunderbird here in portableapps and installed, clean program is consuming around 160MB, even after disabled Lightning and offline mode.
When I run it, open two applications in the task manager, thunderbird.exe (~ 160MB) and ThunderbirdPortable.exe (~ 6MB).

Subject: From where besides Default Programs, and besides under Options, Advanced, Config Editor, is ThunderbirdPortable finding FirefoxPortable?
This is about Thunderbird 45.3.0, not Firefox. Just so you know, I asked this first of Mozilla and was told in full: "Thunderbird passes the hyperlink to the operating system to the default handler (Browser) anything else is portable apps magic." So here I am at the magical PortableApps.

My message filters seem to have stopped working since I was prompted for, and installed, update 45.3.0. I have tried running them manually to no effect. Is there possibly a bug in this upgrade? Or, is there something else I can try in order to get them working again.

Hi. I'm using version 45.2.0 of Thunderbird for Portable Apps. I began a long discussion at mozilla support but nothing where solved. The last post suggest me to look here for help.

So I'm doing this. I just copy/paste the first post in that FORUM, and after this I will offer the link to the mozilla discussion. There you can find a lot of images that explain what are happening.

Hi!
Currently using Outlook Express under XP; being obliged to change OS, I am thinking to use Thunderbird; two needs:

1. I have all my OE mail (folders / account/ etc) in an encrypted file I carry on my keyring-attached USB drive, so I can use all of my mail at home, office, everywhere...

2. I only like Thunderbird 2.0.0.4; (tried newer version and didn't like them).

How can I make the same life with Thunderbird?

Thanks everyone

I have Thunderbird 45.2.0 Portable Apps version installed on a USB2 device that contains a SSD drive.

I run Kaspersky A-V on Windows 7, both fully updated. I have no plans to install Windows 10...ever.

When I load Thunderbird off the PortableApps Launcher or even by directly executing the "portable" wrapper exe, the program starts to consume memory...and eventually lots of it.

Having been a long standing fan of Portable apps and Portable Thunderbird, I now find that it is crashing all the time.
It is the latest version (sorry, can't fell you which one it is since it is freezing shortly on loading).
I admit, the overall size of the application has increased to 4 GB since I move all the IMAP folders into a local Thunderbird folder that serves as my 'store' of emails on my SD card (leaving my IMAP email with more space).
I don't know what I am doing wrong.
Besides, am I right in reading that Mozilla have now discontinued support to TB?

It is tempting to say it /never/ ends cleanly, but honestly it is more like 9 times out of 10.
