I've just replaced Windows 10 with a clean install of Windows 11 and then did a clean install of Thunderbird. No snags and Thunderbird is working fine on all my email accounts. BUT No Thunderbird folders in Windows Explorer are visible. I've looked for my Profiles folder where Thunderbird says it is but it's not there or it's invisible! Similarly there are no visible Thunderbird folders under any program folders. As my emails are working fine, none of this would matter except I do local email backups using a batch program run by Windows task scheduler so I need to be able to get to the profiles folder for this (been running fine for years under Windows 10). Also I'm curious! So, is this entirely a Thunderbird problem, or entirely a Windows 11 problem, or some interaction between the two. Any solutions? Many thanks for any help you can give. Clive

The mother board on my old computer crashed and I needed to get a new computer. Old computer will not post or boot-up. Is there anyway to retrieve and transfer my Thunderbird email files to my new computer when the old computer will not post? Thanks!

I am running Edition Windows 11 Home Version 23H2 Installed on ‎10/‎13/‎2022 OS build 22631.3447 Experience Windows Feature Experience Pack 1000.22688.1000.0 Device specifications; Device name MSI Processor 12th Gen Intel(R) Core(TM) i7-1280P 2.00 GHz Installed RAM 16.0 GB (15.7 GB usable) System type 64-bit operating system, x64-based processor

When I click on install Firefox 124.0.2 the following window pops up stating; Sorry, Firefox can't be installed. This version of Firefox requires Microsoft Windows 10 or newer. Please click the OK button for additional information.

Which opens up a new window giving me the following installation requirements.

Firefox System Requirements Firefox 124.0.2 Windows Operating Systems (32-bit and 64-bit)

   Windows 10 or later

Recommended Hardware

   1 gigahertz (GHz) or faster compatible processor or System on a Chip (SoC)
   1GB of RAM / 2GB of RAM for the 64-bit version
   500MB of hard drive space

As previously noted, my windows operating system and hardware meet the Firefox System Requirements.

Please let me know what needs to be done to install Firefox 124.0.2

Thank you! John

I have a domain, deskdata.com. For reasons unknown, I have to include the domain in my username for the POP3 mail servers. For example, when I use a web browser to log on, the server wants to see petrier@deskdata.com as my user name. Just using petrier results in a failure. I know this seems a bit strange but I was told to do this years ago and it's been working. Trying to install Thunderbird on a new Windows 11 machine has been frustrating as I'm almost there.

I have Thunderbird on two PCs. Thunderbird stopped working on my older PC, Lenovo Z40, Windows 10. I uninstalled Thunderbird on that PC and tried to reinstall. I have downloaded the set up file, but when I open it tells me I need a Microsoft safe app and sends me to Edge browser. I looked at help website but can't see how to overcome this step to get to what is described on the Tunderbird UTube video. I have downloaded the Thunderbird set up file using Edge, Chrome and Firefox browsers. Same problem each time. Thanks

To all a happy holiday season. It's time for another rousing rendition of an oldie, but goody! "Unable to login in at server. Probably wrong configuration,username or password."! Windows 11 version. So I utilize 3 different gmail account addresses. Accounts 1 & 2 loaded up fine. Account 3 has the exact display name, gmail address, and YES, the correct password. I have checked this on gmail from my windows 11 laptop, and my android email app which used Firefox as the browser to get to Google. Soooo...I know, right, it's been posted and somewhat answered here a zillion times. However it's never straightforward on whether its a corrected reply. NOTHING, and I mean, I've looked in every nook and cranny, uninstalled Tbird, reloaded. Cleared everything, cache, registry, tickets to see Taylor S. Nothing works. Yes, I checked for upgrades. Rebooted. Stepped away from computer, watched Seahawks win win win. Came back to computer. Still...nothing magically changed (you know that sometimes airing-it-out does work). Can anyone help here? Thanks Happy happy!

Hi

I recently did a fresh install on my computer and had backed up my Thunderbird profile folder however after reinstalling and placing the backed up profile files into the profiles directory I cant see any of my folders or saved emails.

My Plusnet Mail account is fully operative out of Thunderbird in Windows 10, alongside my outlook.com mailer. I am attempting to duplicate this in a new Win 11 PC and finding it difficult to duplicate my Win 10 Server Settings, due to the ambiguities thown up in hoping to duplicate the Win 10 Tbird 'Server Settings' in the Win 11 'Set Up Your Existing Email Address' questions page.

Win 10 Tbird set-up page confirms my POP Mail Server as 'POP', 'relay.plus.net' and 'Port 110', the Outgiong Server as 'smtpmail.plus'.net' and Username as '"my-name@plus.com".

The Win 11 Tbird 'Server Settings' page (after my own inserted Mail address and Password) includes: 'Incoming Server' protocol as 'POP3' Host Name: (auto-selected) '.plus.com' Port: (empty) Username (empty) - I elected to insert email address "my-name@plus.com".

'Outgoing Server' Host is (again) 'plus.com' Port - empty - and finally (again) ' 'Username' (empty and complered as before with) "my-name@plus.com"

Note: Despite the (fixed) message "Thunderbird will attaempt to auto-select blank fields", the final result advises: "Thunderbird failed to find the settings foryour email account".

Am I making wrong assumptions as to what should be inserted?

One of my 3 emails is not downloading after not being on computer for 2 months.Other 2 work fine. On settings for that account the syn in the menu is not showing? Shows on the other two. On start up it downloaded messages but they don't show? Several had some malware that my antimalware took care of. Messaged downlload just fine on my phone for that account.

cannot download firefox browser because I have an expired chrome browser that I'm supposed to delete first -

However - have tried a dozen or so ways to do just that - or so it appears and still cannot download the

firefox browser and after much frustrated key pounding find evidence chrome is not really deleted - help losing

my mind - I'm 77 years old and not computer literate but not senile either - i hope

I found on your website that I can edit subject lines of e-mails I received using the add on (https://support.mozilla.org/en-US/questions/1155148) .

I downloaded the add on, but unfortunately the

link 'how to install' goes to ? gets me a: Not Found . The requested URL was not found on this server. (http://xenos-email-notes.simplesite.com/416814616)

Since my computer does not know what to do with the downloaded file I need help on how to install the add on. Thanks

I know there are instructions on how to copy certain folders from the old computer to the new one, but I have a slightly different question. I removed the hard drive from the old computer and have it in a case where I can now attach the old drive via a USB connection, to the new computer. If I were to copy the entire C: partition from the old computer to the new one, would that take care of getting all the Thunderbird folders where they need to be on the new computer? I pretty much need to do this anyway for all my other non-Thunderbird folders.

Thanks in advance for any help.

I've been waiting patiently for you all to include mac desktop versions and I was so delighted to find you'd finally done it! I'm still very happy because I LOVE thunderbird but for the first time ever, I can't make it work right. I know the problem is on my end but I can't seem to fix it. I am switching over from Airmail to Thunderbird and the transition has been horrible which is why I was leaving Airmail to begin with. So now I've entered all my info and it seems I successfully migrated the accounts. Unfortunately, it appears that the folder problems followed over to Thunderbird. Some of my 'airmail specific folders' are showing up in Thunderbird and it won't let me delete them. Also, the inbox seems mapped funny ... there's the regular trash can but deleted messages don't go to that folder, they go to inbox.trash - but whyyyyy?

This is the message I just sent to airmail: I'm having the worst trouble with the folders and inbox. I reformatted my computer - iMac Desktop (2017) Sonoma 14.1.2 and everything went fine except with airmail. All my folders for my primary account are gone. The whole folder system seems corrupted or something. I'd like to be able to start over fresh but I can't seem to do that no matter how hard I try. I'm currently running the beta version (bc the regular app stopped working a loooong time ago) and it's a disaster. I currently have one icloud (hschulienlcsw@icloud.com with an alias of heatherschulien@icloud.com) account, private domain accounts (heather@heatherschulien.com and junky@heatherschulien.com) and one gmail account that is forwarded to the junky account. My icloud folders seemed to stay intact but not my others. When I tried to migrate to a new app, it brought with it all the folder problems from airmail. It appears the main problem is with the main account: heather@heatherschulien.com.

Also, how do you add 'alias' emails? Also having trouble setting up the calendars... nothing is working like it's supposed to :(

I'm dying, please help me :)

Had to wipe old Win 11 due to corruption. When setting up from scratch, I use 3 gmail accounts. However when I downloaded Tbird, trying to set up myt 3 gmail accounts, Gmail will NOT authorize Tbird. I have tried all advice that I've seen on forums and on YouTubes. None work. Contacting Gmail is impossible. Forums are not providing any solutions. Does anyone have a proven fix? I appreciate your help. Thank you.
