Thunderbird Community Forum

I am trying to upgrade from ESR to Release. I saved my profile successfully, went to the install page and clicked Download. Got a request to donate, which I did. Then I got a page saying Thank you, Finish installing and enjoy Thunderbird. But there is no way to finish installing and I never got a download file. I've tried multiple times, nothing happens. Help!

In the past, I had followed this post and created the userChrome.css file so that when I have my emails shown in Table View, if one email within a thread is unread, the whole thread is collapsed, but the subject line remains in bold.

With this latest Thunderbird update to version 115.13.1 I have lost the functionality; now the subject line of the collapsed thread shows as underlined. How can I go back to my preferred bold view?

Thanks

I just got a new computer running windows 11 pro. I downloaded Thunderbird, which I used on my old computer(windows 11), and followed the steps to set up my email. I know my email address and password are correct as well as the server settings and I keep getting the following error "Unable to log in at server. Probably wrong configuration, username or password". My email is .verizon.net which is handled by AOL. My husband also uses Thunderbird and verizon email and I checked the configuration against his computer and everything matches. I was able to get my gmail account added so it must be something with aol or windows 11 pro. Any help is appreciated.

After the last update, Thunderbird no longer requires a password be entered to sign into my emails. Hence all my emails are available to whoever opens Thunderbird. How do I get the Profile Password feature back again? This has nothing to do with the Master Password.

Typically if I experience a security certificate exception, thunderbird will popup the certificate exception box, I click to get certificate and am done.

Today I cannot get the certificate popup to appear. which is fine I know where the certificates are managed but I have not a clue how to add a certificate OR what information to enter into the "Add security exception" dialogue box

Any help would be greatly appreciated.

Hi guys, thanks in advance for your help. I use thunderbird on a mac, and with the last updates it seems that I lost the possibility to see -in the search message mode- if the resulting mails have an attachment or not. I'm pretty sure that this information should be there in the past... anyway, is quite uncomfortable to not have this info (I should open all messages to check if there is an attachment). thanks again. Giuseppe

Hi our Kaspersky detected objects but unfortunately our antivirus can't delete all the detected. I try to uninstall the thunderbird but still unable to delete the virus's message.

Hope get the assist for your team.

thank you

Guten Tag, ich arbeite mit Thunderbird auf Linux Mint. Jeweils in den aktuellsten Versionen: Linux Mint 22.1 Cinnamon Thunderbird 128.11.0esr (64-Bit)

Auf meinem bisherigen Rechner begann Thunderbird mit dem letzten Upgrade von Linux Mint langsamer zu laufen. Da ich mir nicht anders zu helfen wusste, habe ich in einen neuen Computer investiert. Obwohl der Rechner jetzt deutlich performanter sein sollte, hängt Thunderbird mindestens genauso wie vorher. Zum Teil ruft Thunderbird auf dem neuen Rechner auch keine neuen E-Mails mehr ab. Ein Neustart korrigiert das zwar wieder, aber beim nächsten Start kann es dann wieder genauso sein.

Alles, was man in den Foren findet, um Thunderbird schneller zu machen, habe ich erledigt. Cache gelöscht, im abgesicherten Modus gestartet (da ist Thunderbird genauso langsam). Auch verschieben von Nachrichten in Archivordner brachte keine wirkliche Besserung.

Ich nutze Thunderbird für 7 Kalender (zum Teil lokal) und 10 E-Mail-Adressen bei unterschiedlichen Anbietern.

Als Add-on habe ich DKIM Verifyer installiert und aktiv.

Ehrlich gesagt, bin ich inzwischen ziemlich verzweifelt, was das Thema angeht. Witzigerweise lassen sich die Entwicklerwerkzeuge nicht aufrufen. Keine Ahnung, ob das vielleicht ein Indiz für den Fehler sein könnte.

Hat jemand eine Idee? Oder noch Fragen?

Herzlichen Dank.

Just a couple days ago I started having issues with some emails from trusted senders that I never had before. When I open the emails, I get this message that I took a picture of. It's related to Apple messages & someone's iphone. I don't own an iphone & have no clue why this started happening recently. Like I said, it doesn't happen to all my emails, just certain ones. Looking at my picture posted, does anyone have an idea what's going on with this?

Can I upgrade my Thunderbird 115.3.1 from 32 bit to 64 bit?

My Thunderbird has recently automatically updated to V115.3.1 but remains 32 bit. When I go to the Thunderbird download page there doesn't appear to be a choice of version.

Hello,

I use Thunderbird 128.5.2esr with xubuntu 24.04.

All of a sudden (I haven't changed anything) thunderbird hangs completely after a few minutes running. The process does not react at all, I have to kill it. Thunderbird process is then stuck on 100% load.

Already testet (with no success):

• Troubleshooting Mode with deactivated Addons
• Disabled Global Indexing (with deleting global-messages-db.sqlite file)
• Waiting for 20min (in case thread/process is running a long time)
• Reboot OS

I have no idea what the issue is. Does anyone have ideas? Thx, Hugo

I can get 200 emails in one day, all with attachments I need to process. At present, the only option for me, in Thunderbird, is to view each email and click on the attachment. If you've ever tried doing that 200 times in a matter of minutes you will appreciate that it's not a good solution. Eudora, which I was using prior to using Thunderbird, but which is old and has problems running properly with the latest versions of Windows, automatically saves all attachments in a specific directory.

Can we please have, as a user-selected option, automatic saving of all attachments in a directory specified by the user? Those who don't need it don't have to use it; those of us who do need it will be saved a lot of time and effort.

It makes sense that you might want your signature text to change depending on who you are communicating with (employer, business, friend, etc).

In Outlook you can enter several signature texts, identified by a name. I sure would like to have that in Thunderbird!

Another possibility would be to circulate among several signature texts, just to "keep it fresh".

Thanks for your consideration.

Any way to minimize Thunderbird to the system tray?

I'm running TB 60.3.2 32 bit on windows 10 btw.

This bug report is irrelevant, as there is no such option in Thunderbird.

Also, all of the addon's that do it aren't compatible with Thunderbird 60.3.2 32 bit.

I assume that the post this could be a dupe of being 4 years old means I can post it myself.

Inbox says how many message are there and how many are unread. A double click will not open the email but I can read it and reply, forward, delete, etc. in the message pane. Only inbox is affected, other folders are fine, Sent, Drafts are also fine. New computer with Windows 10. Downloaded TB 45.8.0 and it worked fine for about 6 weeks until this. Any help appreciated. Thanks.

Full message is: An error occurred while sending mail. The mail server responded: 5.7.1 <r1jacobs@verizon.net>: Sender address rejected: not owned by user cbjake12@verizon.net.

Please check the message recipient "cbjake12@verizon.net" and try again.

I don't know what this means. The addresses in question have always worked before. How do I make the r1 address owned by the cbj address?

I have just upgraded to Thunderbird 60.3.0 and prior to this, I used to just right click in the middle of an email text and I could spell check the whole fields of text easily, with all errors highlighted at once. Now I find this option is greyed out for both new messages and replies. This used to be a really useful tool (and I would have thought pretty fundamental) and I don't understand why it would stop functioning on this new version?
