I have a new desktop running Windows 10. I've had Thunderbird as a mail client for years, but I can't import the old settings from the old computer. Part of it is that I have only the default profile to work from; I no longer have access to the entire older installation.

I've tried two ways: Import from another Thunderbird installation, but it apparently does not recognize that default profile file. I get an error message saying: "Import failed unexpectedly, more information may be available in the Error Console." However, there is no indication of where I can find the Error Console.

So I tried setting up a new account, with the old password and user name, which I can still use to access my inbox online. But I get another error message saying the password is not correct. No matter what I change it to, whether the secure mail key or the latest password, it says the password is incorrect.

Please help!

When I migrated to Thunderbird from other software, I encountered the following problems:

I use POP3. There are 30000 emails on the server, about 10G. It takes too much time to download them all How to make Thunderbird not download all the mail on the server.

I try to import more than 10000 messages locally, and it will still download all the messages

I am using Thunderbird 102.6.0. My email service provider recently changed its servers and I had to reset Thunderbird to correspond. The transition was fine up to a point, because the majority of items in the Sent folder did not appear, only those from the date when I changed the settings. They still exist because I can see them all when I access my account through webmail, but that is inconvenient because I would like to continue performing all of my email activities in Thunderbird, as I have done since it was introduced. Could someone please advise how I might get Thunderbird to download those sent emails from the outlook.office365.com server into my Thunderbird sent folder? Thanks, Kurt

I just downloaded the new Mac Ventura update, and when I opened Firefox all my previous tabs opened up, but my Toolbar completely disappeared, as in there is an empty space for it, and they show when I click on Bookmarks, but not on the actual browser window. The same thing happened with my Add-on extensions, all disappeared, and they're not even showing in my library. When I tried to download them again online, every single one gave me a red error message "An unexpected error occurred during installation." Please advise what's going on and/or how I can fix this to get my normal browser back. Thanks

I am installing Firefox via microsoft endpoint, and deploying multi account containers with the OMA-URI policy for extensions. (this blog page is super helpful! https://securitygeneralist.blogspot.com/2019/08/auto-installing-extensions-on-firefox.html )

The extension by default has containers for Personal, Work, Banking, Shopping.

Is there a way to automatically remove that default container list as part of the install?

Even better, is there a way to create a different default containers list through Endpoint?

Thanks

The RETR command did not succeed. Error retrieving a message. Mail server mail.comcast.net responded: Message 8581 expunged.

FF v112.0.1 & Windows 11 I have my bookmarks from old PC as an HTML file but when I try to import bookmarks on my new PC the only options available are importing from other browsers. Support docs are still showing the old 'import & backup' dialogue. I would appreciate help. Thank you.

Why has this started up again? Pdf files are automatically downloading to my computer when all I want to do is look at the file. So many files that now need to be trashed after looking at them. This problem has happened in the past, but was resolved, only now I am finding it happen again. I do not want to have files saved unless I want to save them, not Firefox deciding that any file I open should be saved. I have Windows 11 & Firefox Version 113.0.1. Is there a way to revert to an older version of Firefox?

Firefox won't stay downloaded to my computer. I am having to download it multiple times, especially if my computer has updates.

On a separate note, when it does actually stay on my computer over night, it never keeps me signed in to my Firefox account. I have to log in to it daily to have my bookmarks and passwords.

Also, it never remembers the theme I have picked for it. I would love some advice on how to fix this.

I've read through a ton of articles, and I can't seem to find a fix.

I recently downloaded a new version of Thunderbird. As a consequence I lost all my addresses! Found a file abook.mab.bak with a date prior to the installation of the new Thunderbird. Tried suggestion of renaming the file and omitting the ".bak" suffix. Didn't work. Can't get rid of the".bak". How can I get my addresses back? Thanks, Tom

I have followed the instructions located here https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer

but still cannot get my new computer to access my email accounts.

Apparently I have missed something with the profile or the proper path for it but I cannot figure out what it is.

Is there another step to take to complete the migration?

Win 10 will no longer open Eudora7 (I have used for over 20 years). I wanted a program that would import My email folders, emails and contacts. So I installed Eudora 8.0 Beta 9 (which will only open in safe mode). But 90 % of my emails get the error "Cannot communicate securely" so I end up hitting OK a dozen times before email opens up. And on those particular emails, the Beta 9 program will not forward them. So I installed Thunderbird 78.7.0 which opens all my new emails. I have gone to TOOLS, IMPORT and it shows emails, contacts etc., but when clicking OK, error comes up "No application found". However, after installing Thunderbird, all those emails and folders that were stored as MBX or FOL on eudora do show under Thunderbird as SBD(folders) & MSF(emails), but will not open up nor show when I open thunderbird. Thanks, Lloyd

When I finally installed the most recent Thunderbird update, to 78.7.0, it crashed and I lost everything, including specialized mail folders and settings.

Is it possible to go back to a date just before that crash, to retrieve and reinstall those folders and settings/prefs via Time Machine on my Mac desktop? It's certainly not the easiest way to do this, but I don't know how else to get all of that back.

Thank you!

So I've disabled Firefox updates because of the personal preferences. It keeps nagging me every day with the modal to update. How do I disable this annoying useless feature?

Firefox 85.0 on mac os.

I've tried searching "about:config" for all preferences that contain "update" and look like timers and changed the timestamps to something in the far future. Still no dice, the update dialog keeps appearing every day like clockwork.

Hi, How do I install Firefox Lockwise for Windows 10? I visited Firefox Lockwise's website (https://www.mozilla.org/en-US/firefox/lockwise/) and there's only installations for Android & iOS devices but I only want it installed in Windows 10. How should I go about it?

Waiting for your reply asap, thank you.

Cool Regards, Pallas

For the past two weeks my Thunderbird 87.0b3 [on linux] has been occasionally starting with a new blank profile. Can someone tell me why this has started to happen and how to prevent this? It seems to be since an update initially caused this, and since then it's happened three times.

The other question is why the update channel is shown as 'beta'? I need a stable install and don't wish to be updated with a beta versions. Can this be changed?
