Thunderbird Portable

Update installed 2021-03-09 is missing thunderbird.exe

Submitted by Klinkert on March 10, 2021 - 12:00am

This morning I installed an update to Thunderbird Portable and after "successful" installation it won't open. I receive an error message that reads: "thunderbird.exe can't be found." And yet, thunderbird.exe is shown as existing in the thunderbird/portable directory with a date of 3/8/2021 and a size of 177 bytes. I tried a second reinstallation. Same error message resulted.

Any help on this?

Creating a new newsgroup-account when clicking on a mailto-link

Submitted by Soldier02modellbau on February 18, 2021 - 9:38am

It seems that there is an annoying known bug in the portable version.
When I click on a mailto-link TB portable open as expected but then want to create a new account for newsgroups.
If I don't want to add this and cancel this process I'm not able to use the link in the way it is supposed to be.
I have to copy the link and manually add it to a new email window of TB removing mailto:.

Seems to me, that DDL isn't working right.

My system is Windows 10 Pro 64 bit.

[Fixed] Thunderbird 78.6.0 auto updated itself despite setting disabling that feature

Submitted by joetron2030 on January 13, 2021 - 10:58am

I have Thunderbird Portable set to "Check for updates, but let me choose whether to install them" checked. I always update Thunderbird Portable with the updated version when it comes out here.

I just had Thunderbird automatically install the 78.6.1 update upon starting up this morning despite the fact that I have my update preference set to the contrary. Has anyone else had that happen to them with 78.6.0?

Is it possible to move all data from ThunderBird portable to Thunderbird desktop version?

Submitted by BirderDeb on January 11, 2021 - 3:42pm

Help please.

I have been using the the portable version of thunderbird for 3 years now, and have been frustrated with it crashing all the time on me. I loved the Thunderbird desktop but switched to portable when I was travelling for work. I no longer need to do that. Is there any way to get my huge amount of data in the portable version loaded into the desktop version. I need stability and not to lose so much time trying to work in my emails.

Thanks in advance for your help.

T Bird 78.6.0 Install Failures

Submitted by rumifan on December 26, 2020 - 7:03pm

I'm not as tech orientated as most people here, and I rarely frequent forums, so my apologies in advance if I break established protocols.

I've reinstalled TB 2 or 3 times with similar results:
- references to C: Data
- no profiles
- no address books

There's a fairly long history of T B as a portable app. I'm surprised at the number of my (and others) issues.

I'm not a total goof. I've successfully installed GIMP, Open Office, Irfanview and a couple of others.

Disappearing New Message folder indication

Submitted by JDMC on December 4, 2020 - 1:01pm

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.

No folders or messages in TB Portable after power cut

Submitted by bobyorke on November 24, 2020 - 8:20pm


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 ...
