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

On android playstore, I am getting a message that a firefox update is available. But there is no description about the update. How to find out authenticity of an android app firefox update and its version and reason for the release.

We have recently enabled background updates in our organization, however I noticed that a requirement for this to work is that Firefox needs to be run with the default profile at least once after the feature is enabled. The issue we have is that not all users are actively using Firefox and therefore they are not being updated. I realize the security flaws won't be exposed if it's not in use, but management doesn't like seeing out of date browsers. Is there a way to force auto updates on all device where Firefox isn't not being used. Background updating is working for the majority of those that do use Firefox.

Also, we do have a couple of users reporting a credential prompt when updating from 119 to 119.0.1. These same users had no issues updating from 118 to 119. I have not figured out why this is happening just yet and why only for a handful of users so far. Would anyone have an idea why that is happening?

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…

Hello,

I need to export many profiles that are connected to my FFX account. these are the profiles found by going to "about:profiles". These do not restore on a new computer after signing in to a ffX account.

I have followed the steps outlined in this support article but it does not work, and I don't think applied to "about:profiles". https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles YouTube videos also do not appear to focus on importing the 'about:profiles'.

If someone knows how to do this, I would be very grateful.

Thank you Liam

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 there. I'm a non-developer but I've been using Thunderbird Beta for a while. I'm not enjoying the current updates (no drag and drop function to move messages between folders!) and would like revert to regular Thunderbird (currently 102.10). I use Backup Thunderbird but I don't think it will load into an older install of Thunderbird. Advice for a safe way to migrate to regular Thunderbird without losing data? Thank you!
