I have made many attempts to move Thunderbird from my old Windows machine to my new one. The old machine was running Windows 8.1, the new one is Windows 11. I've exported, then imported using all the different ways listed but can't get all the data. I've had some success doing it one account at a time including my address book and accounts setup information and they are working properly but can't get the folder data for my accounts or any Local Folders for some reason. I don't want to mess up what I've been able to successfully migrate so I'm reluctant to doing a mass migration again. Is there a way I can migrate doing it one folder at a time without messing up the other ones?

I could extract the Firefox apk from my phone and sideload this onto my quest, but I don't understand why Mozilla don't make an apk available for direct download or make Firefox available via the Meta store. The latter I can understand as it's more time an effort, but I'm at a loss regarding the direct apk availability.

Does anyone know why this is only downloadable via Google Play?

Cheers

I am receiving the following error message when I try to download messages from my Comcast.net account:

The RETR command did not succeed. Error retrieving a message. Mail server mail.comcast.net responded: Message 41395 expunged.

This just started happening yesterday, and I can no longer download any messages from the account. Comcast has no clue why this is happening.

Greetings everyone,

Firefox is my preferred browser and I really prefer the Firefox Engine over Chromium that most other browsers use.

I want to install a backup browser that runs the Firefox Engine in case my Firefox browser has a problem.

I searched a lot and I thought installing this would be the best option: https://www.mozilla.org/en-US/firefox/developer/

However, I’m worried that installing the Firefox developer edition will change my Firefox installation…

I just upgraded to Mac's latest OS 14.0 (Sonoma.) Thunderbird will not load. When I run the application I get a beachball and an "application) is not responding" message. I have tried rebooting and all the "typical fixes.)

Is there an update coming? Something that I can delete to make Thunderbird work?

Hello, I'm migrating from Outlook Express to Thunderbird 102, in Windows 8.1. I'd like to import my Address Book (.wab file) into TB 102. It seems a direct import is not possible (?). I have to convert my .wab file to a .csv file that TB can import. But doing so, I loose all the organization of my old address book (1500 contacts and tens of folders and sub-folders) ! How can I save the organization (folders) of my old address book in TB ? Tks in advance for your answers and solutions.

Hi,

Been using Tbird for forever.

I have a odd setup of accounts. A bunch of accounts that are each one email address. No problem.

And then one LOCAL folder for a bunch of personal email addresses (eg, xxx@mindspring and xxx@earthlink.net combined into one Tbird "account" -- and and a few more email addresses too). This setup has worked fine for years.

BUT, then I upgraded to V115.

All my history in Inbox, Sent, etc, etc. is LOST for Local.

Why? (Honestly, I don't care about THAT so much ... see next question).

How do I get that history BACK??? In those subfolders? If you need it, I can list all the subfolders I use (pretty good guess).

I have TWO profiles apparently. Not clear to me if the install chose the wrong one. Plus a profiles.ini file in the Thunderbird Library folder.

Under Crash Reports: I have an Install Time item for Sept 6 - probably when I installed V115. Useful??

Where do I start?

THANKS! I NEED HELP!!!

After moving my thunderbird 104 profile to 115 supernova (including the profiles.ini file), I can see the full list of accounts and folders in supernova, but none of the emails are visible. I can receive and send new messages, but again - none of them are visible when I want to see them later in the inbox or sent folders. Moreover, the right-click mouse button does not work on the whole list of accounts/folders on the left side of the agent. What to do. I have 16Gb of emails and cannot use them.

I was being nagged to update Thunderbird so did so via download & install as instructed (there was a message 'we will guide you through the update'). That did not happen but I installed 102.2.2 Everything seemed fine except the message pane in lower half of screen is now blank even when I click on an email in the list above. Have tried 'repair' but that had no effect. This is irritating, as the only way I can read my remails is to right click on one and select 'reply' or 'forward' ... it then appears as a new reply and I can see it. But in the upper pane that email rema\ins in bold, ie, unread. I am still getting reminders to upgrade even though 'About Thunderbird' indicates I have the latest version. Hope you can help with this!
