the default font for writing texts is too small for me to easily read. Yet when I send the message the text size too large, How do I control these font sizes independently

After using Thunderbird for many years, suddenly when I try to send an email, I get the error message "daily user sending limit exceeded". Apparently, I was the victim of a phishing hack yesterday, where a fictious email was send to everyone on my contact list. I have not been able to notify anyone because I can't send emails.

Hallo, ich habe vorgestern ein neues Win11 aufgesetzt und dann die neueste Version von Thunderbird installiert. Mir ist jetzt aufgefallen das sich die E-Mails nur mit einem Doppelklick öffnen lassen und das dafür ein neues Fenster aufgeht. Früher waren die Mails mit einem Klick zu öffnen und der Inhalt wurde auch direkt unter der Mail angezeigt . In den Einstellung steht der Doppelklick nicht in der Auswahl sondern als einzige Möglichkeit. Gibt es da irgendeine Möglichkeit um das anders einzustellen, einfacher Klick und direktes anzeigen ohne extra Fenster? MfG

Hello, the day before yesterday I set up a new Win11 and then installed the latest version of Thunderbird. I have now noticed that emails can only be opened with a double click and that this opens a new window. Previously, emails could be opened with a single click and the content was also displayed directly below the email. In the settings, double click is not in the selection but is the only option. Is there any way to set it differently, single click and direct display without an extra window? Best regards

Can't download messages on one of my computers. Account icons show locked, I think. See attached file. Downloads were working but now can't download anything newer than 01 June. How can I "unlock" the accounts? All my other computers are downloading messages just fine.

I've been a Thunderbird user for years without problem. However, since May 22, three specific messages continually reappear after deleting them from my Inbox.

I keep my Inbox empty and it stays that way, except for these 3 messages. Removing them from the Trash folder has not solved the problem.

My email provider is netaddress.com via POP3 account. I signed on to look at my inbox on their site via a browser, and the messages aren't there.

I have tried repairing and compacting the inbox, but the messages continue t reappear.

Do you have any other suggestions?

TIA.

I have been using Thunderbird for years with no problems. However recently, Thunderbird very often simply stops responding. Sometimes it just hangs up and sometimes the program bar at the top displays "Mozilla Thunderbird (Not Responding)". If I try to wait for it to respond, it literally hangs for several minutes before it begins to respond again, and often, it simply never starts responding again. It has simply gotten to the point where Thunderbird is practically unusable. All my other application software continues to work with no problems. It's just Thumderbird.

The version number in this submission may not be correct. I can't provide the real version number because of the hangups.

Any suggestions?

Dear all,

For aprox. 3 weeks now Thunderbird asks me a short time after startup for a login.

It shows up a dialog with the text : "https://caldav.gmx.net verlangt einen Benutzernamen und ein Passwort."

The problem is, that I maintain several GMX - accounts and I've no idea, which credentials I have to enter :/

How can I find out ( without inspecting or debugging the source code ;-) )

THX in advance and best regards!

Hi all,

I've been using Thunderbird for eons but yesterday morning it started freezing up constantly.

It freezes up ("Thunderbird is not responding") every time new emails are received or any time I take any action while the Inbox folder is open. So, if I delete an email it freezes for a few minutes. If I do anything pretty much, it freezes up for a few minutes. Then it comes back and I can do another action, and it freezes again. This only seems to be happening when I have the Inbox open - if I go to other folders it seems to function normally.

Things I've tried without success: - Troubleshooting mode - Adding exceptions for my profile folders to Windows Defender - Compressing Inbox (and Trash and Junk) - Repairing the Inbox index

This doesn't appear to be a memory issue - right now, memory use for my entire system seems to be hovering at just over 50%. But Thunderbird is still freezing.

My Inbox folder is very large, but it's never been an issue before and nothing significant was added yesterday when it started failing.

Any suggestions appreciated!

Thanks

My inbox folder costently says it has more messages than it displays (I can see the missing ones by searching). I have tried repairing it, looking at filters, etc., but nothing seems to work. See picture. Thank you!

Yesterday I had to change my Spectrum email - I have an old road runner email address and swapped over to spectrum.net server from the old server. In this process I had to update my password to access the server.

When I updated per the instructions from Spectrum I was able to do a normal download into my Thunderbird inbox. This triggered me having to input the new password. I did check the box to update the password and save it. After the one time download I cannot get Thunderbird to download emails. I can send emails with no problems but cannot download. No way can I get a download - it does not on initialization, at the set time nor with the manual request.

Spectrum is no help - their web mail works and it's my problem. I realize this is an old system, legacy and all that - anybody got a magic fix?

Any idea on how I messed this up?

Thanks.

I've been using T-bird since nearly the beginning, and I've always been able to search for a string in a message by hitting the slash ("/") and typing my search string. This appears to be a shortcut for Ctrl+F (on Windows, currently Windows 11).

With T-bird 151.0, when I press "/" it is ignored... the first time I use it. If I press Ctrl+F and do a search, then I can start all subsequent searches in that message with a slash. If I close that message and open another, I must again use Ctrl+F the first time I want to search.

My muscle memory constantly forces me to type "/<string>" to search, but since T-bird ignores the slash, the following characters immediately take action, usually causing me to navigate away from the message, mark them as read/unread or as junk, etc.

Since I can use "/" on subsequent searches, I'm thinking this is a bug, not a feature removal. Can this be checked/confirmed? ...thanks!

I'm not sure exactly when this problem started but it could have been when I had to move my primary email from Xfinity over to Yahoo. Also not sure if this started after a recent Thunderbird update. I can not send new emails nor can I forward old emails. Haven't tried reply but suspect it is the same. This is the message I get: Sending of the message failed. An error occurred while sending mail. The mail server responded: Request failed; Mailbox unavailable. Please verify that your email address is correct in your account settings and try again. All settings and passwords are correct as I can receive and send from all my different accounts using browser. I can send emails from my accounts, on my iphone, though not using Thunderbird on iphone. Account settings and passwords are the same on the phone.

I have been having troubles logging in with my Microsoft email account on Thunderbird (hotmail). When I fill in the name and email address, a pop-up appears with the OAuth2 authentication but the only thing that ever appears in this pop is the message "Unable to connect" with some additional possible explanations.

I have looked online a lot for solution but nothing seems to work. I have cleared the cache, removed all mentions of the email account (it was working before until I added a passkey to the account).

Other reasons I have seen is that the request might be intercepted by certain problems like Apache or Nginx etc. I am running an instance of Nginx on my home server, which is a different device. But I have temporarily turned it completely off but it did not change the situation. The same story with and instance of PiHole, it turns on my homeserver which is a different device and also had to turned off.

The machine I am running Thunderbird on is a Windows machine. I have also tried booting into safe mode with networking but also that did not do anything.

I have tried copying the url on the top of the pop-up window and pasted into several web-browsers. There is does load and I can select the correct passkey to login. But the data that comes back from it is not being given to Thunderbird of course so it does nothing. But the fact that it is able to load outside of Thunderbird makes me think it is a problem on the side of Thunderbird.

Could you perhaps help me set up my email on Thunderbird?

Hi, I am hoping that the community can help me find an answer to this. I have two computers that I use for work. The one in the office has TB running all the time and before I leave for the weekend/vacation I would close TB, copy the profile folder to a USB (or copy it to cloud) and then paste the profile folder on my work laptop (at home). While all the settings get copied (local folders structure, addons etc.) as I use IMAP, it downloads all the mail on the new system regardless. I thought that it should have the latest mail downloaded as part of the profile folder, is that not the case? The bigger issue is that none of the Completed Tasks Lists, Templates, etc. get updated. It still shows all the older stuff on the work laptop and no updates carry over from the PC (at work). Going through the profile folder I see multiple copies of the files prefs.js, folderCache.json, global-messages-db.sqlite appended as: prefs-computername.js and folderCache-computername.json etc. (The computername is the name of the PC - office/laptop) The profile name is the same between the two computers. TB is only started after the profile is copied locally. TB version is the same between systems. I am left scratching my head why somethings are copied but not others. Hoping that the community can help me here. Thanks!

I have several Windows 7 computers running Thunderbird and have 13 POP3 accounts to retrieve. These computers work fine. It takes about 5 seconds to check all 13 accounts if there is nothing new to download. I have two Windows 11 computers that take about 50 seconds to go through these same accounts under the same conditions (nothing new to download). I have done a lot of searching for answers, but nothing helpful has come up. Any ideas on what might be causing this? Seems like it would be a common problem as both Windows 11 computers do the same thing. Both are Windows 11 Pro. Thanks for any guidance.

I am using Windows 11 with the latest Thunderbird 151.0.1. I have been trying to add color to the column title background in the message list using the userChrome.css with the following:

1. sizeCol {background-color: #dcfffc !important;}
2. recipientCol {background-color: #dcfffc !important;}
3. subjectCol {background-color: #dcfffc !important;}
4. dateCol {background-color: #dcfffc !important;}

1. spamCol {background-color: #dcfffc !important;}
2. fromCol { background-color: #dcfffc  !important;}
3. attachmentsCol { background-color: #dcfffc  !important;}

They work except the 'from', 'attachments' and 'spam' columns title backgrounds. Can anyone see what I am doing wrong? Or is there a way to color all column title backgrounds in one line? Thanks

I can not get my google workspace account to authorize in Thunderbird. Using IMAP setting. Thunderbird automatically finds the correct server settings, but when I hit "continue", it gives an authentication error.

I have spent extensive time with the google workspace admin console help. This is the final result: "Thank you for trying all the steps so far. Since Thunderbird has already been added under App Access Control in the Admin console, IMAP is enabled, and cookies/cache have been cleared, but the authentication error still persists, this points to a possible issue with the application’s client ID used by Thunderbird for OAuth. In this case, you will need to contact the Thunderbird support team to verify the correct client ID for their OAuth implementation. Once you have the correct client ID, we can then configure it properly in the Google Admin console so the authentication works successfully. We’ve confirmed that all Google Workspace settings on our side are correct, so the next step must be coordinated with Thunderbird’s team."

Therefore, here I am.
