Thunderbird Community Forum

For months I was experiencing the problem of "Thunderbird not responding" occasionally. It was a short duration issue (a few seconds to a minute). I reinstalled Thunderbird several times without success. I read almost every comment available online about this problem and I tried many ideas and recommendations I found without success. Most recently the problem became so serious that it was not a nuisance any longer. It was nearly impossble to work waiting for minutes to open an email or to continue typing while preparing a message and being interrupted by the problem I am describing. I ran Thunderbird in safe mode and determined that none of the add-ons is causing the problem. I turned the firewall OFF and determined that firewall was not causing the problem. I then decided to run Thunderbird in Offline mode and found that the program works normally. Then while in Offline mode I decided to download more messages and the program asked me if I wanted to switch to the Online mode. I said yes. New emails were downloaded and without going back to the Offline mode I was able to work normally without any occurrence of the "Thunderbird not responding" problem. I have been using this workaround for several days now. I download a number of eamails. I try working in Online mode and I cannot do it. I switch to Offline and work fine. I switch back to Online mode and I don't see the problem any longer for the whole day. Do you have any idea as to the origin of my proble? I am running Thunderbird 115.10.2 64 bit on Windows 11. I had the problem originally using Lenovo T490s and more recenlt Lenovo X1 Yoga

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.

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.

I get a message like this every time I start Thunderbird. The topic came up last year but the conclusion was along the lines of "...this problem will be fixed in version 128" but it was never clear whether or not the User followed Mozilla's support replies or what they had to do to clear the email message from Thunderbird. .....Well I'm running version 128.1.1esr and the problem still exists.

My questions:

1. What is Thunderbird trying to do? Compact individual email files? Compae from ct the whole Thunderbird Profiles folder?

2. Is the problem the size of the Profiles folder or the overall size of the hard drive the Profiles folder resides on? What is the Hard/solidstate drive is the maximum?

3. Is the problem related to the amount of Free Space left on the Hard/solidstate drive or is the issue the number of individual files?

4. Is the issue related to the number of Thunderbird files and/or folders OR is it related to the total number of files and/or folders on the hard drive?

5. Is there a limit to the number of sub-folder levels that Thunderbird can navigate?

Thank you.

I'm on tb 128 and use roadrunner. I see my emails on spectrum server but can't download them? I was using pop, they said imap is needed.

   Username: Your full Spectrum email address

   Password: Your Spectrum email password

   Protocol: IMAP

   Incoming Server Port: 993

   Outgoing Server Port: 587

I use an AOL email account and Thunderbird on my Mac. In Thunderbird, the junk mail folder - which AOL call "Bulk Mail" for some reason - has moved to the Trash folder and I can't get it out. It's a Thunderbird problem - if I go onto my account at AOL.com, everything is normal. How do I get it out? I've tried cutting and pasting it, creating a new folder...nothing seems to work. I don't want to empty the trash in case I no longer have a junk folder at all

On my workstation the Thunderbird e-mail data is saved in the C:\Users\[My Name]\AppData\Roaming\Thunderbird... directory.

The data consumes considerable hard drive space and I would like to create a directory on my F: drive (that has 100+GB of data free) to "off-drive" the data. If it's even possible, how do I configure Thunderbird to use this different data directory on a different drive??

BTW, I tried to do this by copying the data/profile in the above C: drive directory to my F: drive. I changed the "Local Directory" setting in the "Message Storage" pane on the "Server Settings" window in the "Account Settings" appropriately. I even changed the path in the profiles.ini file in the default C: directory. This process didn't work and resulted in Thunderbird demanding that I create a new account. All returned to normal when I copied the Thunderbird data to its original location.

Outlook says that it will no longer let third party mail apps like Thunderbird to access Outlook email as of September 16, 2024? What do you recommend?

"Action Needed – You may lose access to some of your third-party mail and calendar apps

Update your sign-in technology before September 16th, 2024 to maintain email access.

The safety and security of your information is top priority for Microsoft. To help keep your account secure, Microsoft will no longer support the use of third-party email and calendar apps which ask you to sign in with only your Microsoft Account username and password. To keep you safe you will need to use a mail or calendar app which supports Microsoft’s modern authentication methods. If you do not act, your third-party email apps will no longer be able to access your Outlook.com, Hotmail or Live.com email address on September 16th.

What do you need to do?

If you are receiving this email, you are currently using an email or calendar app that uses a less secure authentication method to connect to your Outlook.com email account. You will need to upgrade your third-party mail and calendar app to a version which supports modern authentication methods.

Microsoft provides free versions of Outlook for your PC, Mac, iOS, and Android devices which can be easily downloaded and connect to your email account. Using an updated version of an Outlook application will ensure you are connecting in the most secure way.

How can you set up your Gmail, Apple Mail, or other third-party mail application?

Various non-Microsoft applications will have their own steps for connecting to your Outlook.com email account using modern authentication methods. See our help article - Modern Authentication Methods now needed to continue syncing Outlook Email in non-Microsoft email apps. However, you may need to contact the creators of those applications to provide you with instructions. In many cases, simply removing and re-adding your account with the latest version of that application will configure it to use modern authentication methods.

Copied Thunderbird Profile from Windows 10 PC, pasted to Windows 11 PC - No email history or address book

I followed the steps to copy the profile from the old PC and paste it into the folder on the old PC.

Thunderbird is using that profile, but there are no email history or address book.

When I let thunderbird compress the inbox and other folders, the not read flags on all new emails get reset as if I have read all of the new emails. Compressing the inbox and other folders should have no effect on the flags showing a message has not yet been read. That only makes sense. The not read flags getting reset started happening several versions before 145.

when i oppened tbird on windows 10, it showed a page to obly my for a donation. i had made a donation short ago, but eventhough, i just made another one time donation. when i open tbird again, i can not get out of the donation page. what should i do please???????

If there's one thing I can count on, it's that the next version of Thunderbird will be more buggy & unstable that the previous version, and v 140 certainly does not disappoint in that category. It crashes & closes multiple times per day. Any time something else may be using a lot of resources, Thunderbird freezes up and if I click on it, the app crashes & closes. At least the previous just stayed greyed out until it was able to complete the task and didn't crash & close. Great job Mozilla.

For years I have used the extension 'Calendar Tweaks' because it colorizes the entire event in the calendar. This extension is no longer compatible with versions of Thunderbird after 74 so I have stop updation after Version 69. However in resolving problems with authorization I needed to update to the current Version of Thunderbird so my events in the calendar now just show the category color at the edge of the box instead of the entire box. Is there a way in Thunderbird to colorize the entire event box or another extension that does this.

Apparently I have changed the Thunderbird account settings causing an alert message on all incoming emails. As shown in the bottom of the example attachment it reads, " The unique identity matching the prom address was not found. The message will be sent using the current from field and settings from identity Bob Poulnot <atldetective@gmail.com>.

Also by opening this incoming email it is showing at the top that it is "From" Bob Poulnot <atldetective@gmail.com> as a reply. I did not click on reply.

Please help. Thank you

Need help setting up my domain name with godaddy and Thunderbird email client. need to get DNS Records from godaddy also. Having more trouble with this than I should, I think. I have already setup an email account on Thunderbird with earthlink/mindspring and icloud. No problems at all, in fact, both were very simple. But no so much with the domain name and godaddy. Any assistance will be greatly appreciated.

I don’t know my Mozilla Thunderbird Password for peterrgroom@hotmail.com Therefor I can’t sign in How can I either retrieve or reset my password?

Please tell me what the difference is between "size on disk" and "user quota"? I don't understand why my mailbox is full when all folders take only 1/5 of the available space. My hosting give me 5GB, a user quota in mailbox is 4.7GB (in the app for computer: the main folder containing all other folders - properties folder - Quota - Storage: 4.7GB), size on disk is 853MB (in the app for computer: the main folder containing all other folders - properties folder - General Information - Size on disk: 853MB), and the weight of all folders is ~1040MB (the sum of the weights of all individual folders in the main folder). None of the numbers match. I understand that the sum of the weights of all folders is probably supposed to be 853MB, that the discrepancy is due to rounding the numbers. I understand that some space may be "lost" from the hosting because installation files take up some space, so I actually have 4.7GB to use, not 5GB. However, I don't understand why my mailbox is full, when from 4.7 GB only 853 MB is used?
