Thunderbird Portable

I just downloaded the German version and found out after the installation that Thunderbird can be opened, but the application is completely empty.
Can anyone confirm this?

Hello.
I am using Thunderbird Portable Edition 78.5.0 on PortableApps platform 17.1.1. I have many (over 70) folders, most of which are populated by filters which are enabled to run automatically.
In the past, folders which had new messages were shown by a change of colour together with an asterisk. More recently, this is just shown by the colour of the folder name changing from black to blue; this is not always easy to spot, especially since my eyes are not what they were.

Hi,

We just had a power cut and now my Thunderbird Portable (78.5.0, 32-bit) is not showing any mail accounts, folders, or messages. I've checked my data\profile folder and I believe my folder structure and mail is there. In my data folder I have found prefs.js, and it has lots of relevant stuff in it, including lots of "mail.account" entries.

Can anybody help me to restore my mail please? Just for info, I use MailStore Home from time to time, but sadly not frequently enough to simply restore everything. I'd be grateful for any suggestions ...

Since some day the application does not run anymore under wine 5.0.3 Ubuntu 1 (Firefox too).
The Mozilla crash reporter starts every time.

Best regards

I read that I can launch "normal" Thunderbird with the "-p" parameter to get to the ProfileManager and switch there to "Offline Mode".

That in turn would open TB without access resp. message transfer connections in+outside.

Perfect. Thats exactly what I am searching (for temporary test purposes).

Unfortunately users cannot start PortableApps Thunderbird with the "-p" parameter..

ThunderbirdPortable.exe -p

So how else can I switch PortableApps Thunderbird to "Offline Mode"?

Starting today, it was impossible to get the profile up, I was presented with a blank page.

for the moment, my workaround was to install thunderbird on my PC, click on troubleshoot, then about:profiles, and finally create a new profile by pointing to my exiting one, copied from the portable installation, and making that the default. (the portable application has to be closed at that point, or it won't allow you access).

I couldn't direct to the portable profile from the portable app, it defaults to local appdata and won't redirect to the portable.

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
}
}
