Trying to remove Thunderbird. Windows add or remove programs isn't working. I'm trying Program Install and Uninstall Troubleshooter, which needs Thunderbird's product code.

I can't find it on the site. Can someone give me a hand?

I downloaded Thunderbird into a new computer and there are a lot less emails than on the old computer. I cannot find a setting to download the rest of the emails. Can you please help. Please send me an email telling me if I can download the rest of them.

I wanted to install Thunderbirds on my Ipad (Apple Air). In the AppStore I didn‘t found a Link for a Download, - so I used a downloadlink in the Internet. About 149,…MB. After the complete Download I couldn‘t install the Programm on the IPad. The Icon is „grey“ designed and seems to be not activatable. I‘ve had the same problem with libre office.bold text

1) Firstly, I posted earlier because I needed to add a second app-specific password to my account. What I discovered was that my Account Settings tab had disappeared. I got a response from someone that I had to change my email password, and it would reappear. IT DIDN'T. So I've changed my password and I still have no access to my Account Settings! What do I do? I really don't understand why, if I could log in with my old password, what the point is to change the password to correct the Account Settings problem. I need HELP!

2) I need HELP getting either Thunderbird (my normal email client) connected or change to a new email client that will actually work. The problem is that Thunderbird for some reason can't connect even with an app-specific password! I have been struggling with this for more than two days and there is NO HELP from GMX that solves the problem. And it's not just GMX, there's no help from Thunderbird. My sole source of help has been to post queries on the internet and follow what AI tells me which has been only part right. At least it's something. But now I can't even change my account settings!!!!

Can somebody PLEASE help me? [edited email from community support forum]

Keep on downloading Mozilla Thunderbird Release but it keep coming up as ESR. How can just have Release? My email account with Mozilla is [edited email from community support forum] @pc-q.net can you reply there.

Hello,

for some reasons I need to downgrade a TB installation (Mac silicon 148.0.1) to the ESR channel, 140.8.1esr for Mac silicon.

I read articles in the KB where Mozilla discourages this, but I would avoid to move 15Gb circa of emails by hand copying and pasting them...

So is there anyone that has tried this before? Any suggestion how to do it without loosing e-mail in th process?

Thanks fr your support.

Hi! I am a tax accountant. Considering updating from Thunderbird 97.0b3(64 bit) to latest non-beta version. Is this feasible? Is there a separate/special update process from Beta to the latest? Also would like to continue to use my POP account set-up at Optimum(Cablevision) here on Long Island. Email (Outbound)SMTP and (inbound)POP mail servers have to remain the same. So initially , I have to backup all my existing Thunderbird data & Profile.

I have used Thunderbird for a long time; previously used Eudora. The problem which I am trying to prevent is that when I try to send a client their encrypted PDF of their tax returns and related instructions, etc. my document database or data magt system, namely File Cabinet Solutions show in the activity log "Waiting for user input" --- so no email is created which would have all the requisite documents attached. The last time helpful client send feature worked in my tax software, Ultratax, was June 27, 2025. Ultratax could not figure a solution, after several weeks & suggested that I upgrade my Thunderbird.. Can anyone help?

Thank you! Best, Mike Porcari--- [edited phone# from public community support forum] (cell)

Ich habe WIN 10 auf meinem PC und kann nicht auf WIN11 upgraden. Hatte Thunderbird schon installiert und problemlos im Betrieb. Leider konnte ich ab ca 19.12.2025 keine Emails mehr schreiben und empfangen. Ich habe mittlerweile zig Stunden versucht das Programm wieder zum Laufen zu bringen, aber erfolglos. Ich habe es 2 mal deinstalliert, aber mittlerweile kann ich es noch nicht einmal wieder richtig installieren (habe alle Thunderbird-Dateien - auch den Cache - auf dem PC gelöscht). In GMX Mail habe ich die Berechtigung Zugriff über POP3 u. IMAP erteilt. Ich kann leider keine jpg Datei mit näherer Beschreibung hinzufügen...

I have no idea what I have accomplished and what I have to do next. I am here because I cannot access my current email account,and neither can you. I paid $20 but I still see a pay page. Get Thunderbird installed and working. I had Thunderbird years ago and lost it, I think someone wanted me on the foxinternet.com program. Assume I am a new person to access the internet.
