Thunderbird Portable

In Thunderbird 38.3.0 packaged by portableapps.com.
In Tools->Options->General: "When new message arrives" -> "Play a sound" (checkbox activated) clicking "browse" does nothing, and cant enter the path manually either.

Somehow my local folders have collapsed, and I can't reexpand them. Some I can see in explorer, but some are invisible. I use the portable version. thanks.parmil

When I tried to create a new folder with explorer in the default "local folders" folder on my hard drive, I am told there is already a folder with that name. That's what I mean by invisible.

Hello,

I've updated Thunderbird Portable from 31.7.0 to 38.3.0 and lost all saved passwords. Luckily when I turn back to version 31.7.0 with my profile folder I still have all the passwords remembered. But now I can't use the latest version of TB because I have too many accounts so it would be extremely frustrating if I have to enter all the passwords into the latest TB's version.

Any suggestion how to use the latest version without enter all the passwords again ? I am using Windows 10 Pro.

Thanks

hello,
I'm downloading right now the entire content of my Gmail account in my thunderbird portable through IMAP.
My gmail is 15GB and 41470 messages. Now I've downloaded almost 3636 message, which means 91% of the entire messages, however the size of my Thunderbird folder is only 2.44% ... how is this possible? I was expecting the same size of my actual Gmail account, is there any sort of compression?

Hello; I like TB Portable, currently use 24.3.0, considering upgrading to current 38.2.0. Where can I find the improvement list?

Also, I see many comments RE use of USB drives, and understand that is the main purpose of TB Portable, but I want to report it is excellent as a primary email client on PCs -- I use it on my desktop, and easily copy the folder to transfer everything to my laptop, or wherever I need it to go. I prefer POP, and like to keep of all my emails in one location under my control.

Hello,

just updated Thunderbird to 38.2.0 and having now severe issues in forwarding, responding and writing emails (Thunderbird duplicates attachments, taking recipient of previous email as default for the next email, sometimes very slow inserting of names from the adressbook, hanging while typing, loss of "copy" and "cc" fields in the adress area).

I went through a TSA security checkpoint the other day and when I got to my hotel my Thunderbird account data was either corrupt or missing from my SuperTalent USB SSD drive. Other apps were unaffected. Is this possible?

After installing Portable Thunderbird, I followed the instructions under Copying Your Local Thunderbird Settings (https://portableapps.com/support/thunderbird_portable#installing) to give Portable TB the environment I had been using with non-Portable TB. Of course, I copied my non-Portable prefs.js file along with everything else.

I have Thunderbird Portable and Firefox Portable set up and working. When I click on an email address in a web page, instead of opening a new email in Thunderbird as I expected, it brings up a dialog asking me to set up a Newsgroup account. What???

I just want to send an email from my Thuderbird Portable email.

After updating from 31.7 to 38.2 Thunderbird Portable, installed locally on a HD with Win7 Pro, I could not send mail through an external server. I was able to receive mail through the same server. When I downgraded back to 31.7, I was again able to send and receive mail.

On trying to send mail, I got an Alert box that said:
An error occurred while sending mail. The mail server responded: Administrative Prohibition. Please check the message and try again.
