I installed TB 115 portable to review it. I now have it all setup and configured to my liking. Now I want replace my installed v102 with the new portable ver. My plan is to upgrade to installed from 102 to 115.5.2 (same as portable). But what files/directories do I need to move to do this? I have the Installed ver on C: (Win10) and the portable on D: .

Road map please.

I had made a complete Timemachine backup, and migrated to a new mackbook Pro I do see my profile ( jgt4oy0r.default - 18GB) in ~/Library/thundebird When I launch Thunderbird, it seems it is pushing me to Account Setup.

Any clue?

On new device I downloaded Thunderbird from MS Store and I tried to copy my old profile, however despite successful copying to AppData\Local and AppData\Roaming, Thunderbird doesn't see the profile. I created a new profile to try renaming and replacing the files, but I noticed that folder for the new profile didn't appear in AppData locations. I tried to open them via 'about:profiles' and I received an error, I also tried to rename my old profile to new name I found there - but nothing helped. As my last attempt I tried to import files via Import Tool, but after choosing the correct folder, Thunderbird shows an error (more details are supposed to be in error console which I have no access to, as the files don't exist physically in AppData location). Export also failed as the file size exceeds 2 GB.

Is it somehow possible to successfully copy the profile to the version from MS Store? I'm sure that downloading installation file from Mozilla site would help, as I've been copying profiles many times before this way, but here I need to use MS Store as a single point of installations.

Over the last several months I struggled to get Thunderbird to allow me to set up email accounts for POP3 mail handling. For now, I have the accounts added using IMAP mail handling; however, in trying to fix the problem I removed and reinstalled Thunderbird a number of times. As a result, I seem to have lost all my contacts. To be more precise, there are no entries when I click on Address Book.

I have a dim recollection of having read that TB saves multiple Profiles and that Profiles contain many things including downloaded email and address books. I hope that is the case and that there might exist an older version of a Profile that contains my address book. If that is true, I need help finding the older Profiles, determining if they contain my address book, and recovering the address book without disturbing my current TB install.

Can anyone confirm or deny my supposition? If confirmed, can anyone tell me how to go about recovering my address book? I'm running TB v.115.7.0 on Windows 10. I believe I'm up to date on both.

TIA

Firefox is my longstanding browser (on Windows 10). I wish to make use of the Firefox PDF viewer, but have been unable to gain access to it. If for the purposes of an attachment I click on "Open with", Firefox does not appear among the viewers offered. I'm not tech savvy, so a step by step (idiot's) guide as how I can gain access to and then make use of the Firefox as my default PDF viewer will be greatly appreciated, please.

""Description: COX Server Name: smtp.mail.yahoo.com Port: 465 Connection Security: SSL/TLS Authentication method: OAuth2 User Name: your user name, duh - Mine keeps changing the user name to the last name I put into any of my 6 accounts. The only way it will send mail is if the correct user name is in the correct account (obviously). Why is it changing constantly? click OK""

I've read the "fixes" from 2023 and they do not work for me. I tried changing the DESCRIPTION to blank, didn't work. Changed them to the corresponding e-mail for the account. Didn't work. Changed it to "SMTP" with the corresponding e-mail. Didn't work.

It keeps changing the last one I edit to the one I edited before it. It's driving me crazy. Won't send mail unless the User Name is correct (obv.)

Whole mess started when forced to switch from Cox to Yahoo recently. Seems to be working other than TB changing the name as soon as I type in the next one in the next email address and then it not working until I change the User Name back to the proper e-mail address of the 6 accounts.

Have two computer with same email. My Wife's computer password got corrupted and unable to get messages. I deleted TB and deleted any reference to Thunderbird in the registry. Turn off and restarted PC, downloaded new install and run and all the setting from before automatically were in place and still could not get pass the password issue. My computer does not have any password.

My wife's PC, under setting, does not have any saved passwords or a Primary password or even the "Use a Primary Password" checked. If it is checked there is nothing there. It just will not get passed the password issue being always asked when trying to "Get Messages".

How do you get rid of all the infor, setting, password requirements and to be able to restart with a clean Thunderbird install or get passed the password issue? Making my brain hurt.

Had to reformat and reinstall my Intel Mac with System 10.4.11. Can't download install dmg from the ftp site because my id and password don't get me into the FTP website.

Does anyone have the installer for 3.6.28 version of Mac Firefox

Hello, I need to backup my Thunderbird instance on computer A to another computer B on the local LAN. Probably by installing Thunderbird on computer B and copying from A to B the Thunderbird message store, including all folders, messages and attachments. How is that done? Thank you.

Hello Dear People,

I have been using Thunderbird to great satisfaction. When my computer of 10 1/2 years died, I started to use old laptop of my son who made me the second user. I d/l Thunderbird on my account and it all went well till a few days ago. No Thunderbird. I d/l again, profile not found/inaccessible. I did see advice here from last year, looking for the profile under Users, app data, roaming etc. but to no avail. There is no profile.

How to solve this problem? Also after d/l the set-up, the thumbnail looks strange, like half of the image as shown in the picture. I tried d/l a few times, same result. I was very content with the program. I want Thunderbird back!

Thank you for your advice! Dorith

HI Antone I have spent about two weeks on Google etc trying to export my Thunderbird address book to my Galaxy S20 5G. I just have failed miserably. I guess it's because I am 79 and tech has beaten me. Can anybody p[lease help. Cheers Alan Jones

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!

We have been using Thunderbird with a Cox email account. Cox has just transferred all its customers to Yahoo. I want to use Thunderbird with Yahoo. How do I set that up?

Just trying to upload my email account. It has only partially completed the upload. Files are missing and alterations I made to my actual email account are not showing. Tried taking it off and reloading but has exactly the same errors!

This has been a headache. Cox has had us migrate our accounts to yahoo. I have been able to do most of my emails, but my husband had yahoo tech help him and one of his emails will not download to the thunderbird account. The tech did a pop.mail.yahoo with this one but created new imap accounts with the other two. I tried to create a new account but it says Incoming server aleady exists. So I deleted the account, shut down Thunderbird and brought it up and tried again. I got the same message.

I am new extremely tech savvy but know a little more than my husband. If someone could please help walk me through this, I would appreciate it. Thank you.

About a week ago I started getting these update error messages stating "Update available - Firefox couldn't update automatically. Download the new version". I've also tried clicking "Learn more" on the error message but it's a dead link. Going into the settings for updates I am set to auto update, but when I manually check for updates it says "Failed to check for updates".

The help article on this issue simply tells you to download and manually reinstall Firefox, but I'm having to do this nearly every day. I work in IT myself so I know a "bandaid" workaround when I see one. Is there a solution to this issue?

I wish to install and use the Firefox browser on my old 64bit Windows 7 laptop.

I believe the last v115 will be the last Windows 7 compatible version of Firefox, if this is correct where can I find this or the correct version of Firefox to download and install on my Windows 7 laptop?

The Firefox website only seems to provide v119 now.

Thanks, Graham

Dear community, I get the error "There is no default mail client or the current mail client...". <send to> and adding files to a new message by programs like pdf printer stopped working. It worked before. Suddenly stopped.

what I did with no results: In 'Default apps' - Thunderbird ofc. 'Email' needs to be set as 'Thunderbird' reinstallation of TB 64b. installation TB 32b. HKEY_LOCAL_MACHINE\SOFTWARE\Clients\Mail​, -> Mozilla Thunderbird HKEY_CURRENT_USER\Software\Clients\Mail -> Mozilla Thunderbird HKEY_CURRENT_USER\Software\Clients\Mailto -> Mozilla Thunderbird HKEY_CLASSES_ROOT\mailto\shell\open\command -> "C:\Program Files (x86)\Mozilla Thunderbird\thunderbird.exe" -osint -compose "%1"

I will add that if I set the default Outlook, it works (Now I have deleted it).

What should I do to make Thunderbird work?

I need to download & install TB ver 31.8.0 to a newly installed system running ubuntu 22.04.

My earler installation of TB 31.8.0 on my other computer has critical information on it, running under ubuntu 14.04. It's so old that i cannot access the internet on it.

So I'm hoping to install TB 31.8.0 on this new computer, copy my TB profile from my old computer to this new computer, then do the necessary updates to this newly installed version of TB 31.8.0 to bring it up to TB vers 115

Thanks in advance!
