I-Thunderbird Community Forum

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?

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

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!

My old provider has stopped supporting my old email address and I have changed to a gmail address. How do I remove the IMAP and smtp settings etc for my old email address? Also remove all trace of that unwanted old address please?

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

Mozzilla fonctionne mais je ne peux plus faire "envoyer" mes mails. C'est terrible d'autant que n'y comprends rien . Je rédige-sur la page "Rédaction" et après il n'y a plus de case "Envoyer." par contre je reçois les mails J'ai glané les infos au bout de 2 jours  : IMAP Je sui "Orange" Sortant SMTP/SSL/TLS port 459 Entrant SMTP/SSL/TLS port 995 et quelque part  : version 140.II.Iesr  ? Vous pensez que c'est grave ? ça fait 10 ans que ça fonctionnait

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 have all my past emails in specific folders within Windows Mail currently. I have three email accounts. I want to set up Thunderbird and import all the folders of emails into it and access all three accounts from within Thunderbird. I have a Master computer running windows, a tablet and a phone. I would like each device to be able to access all the email accounts and the stored folder tree within Thunderbird. I would like the Master computer to be set up with POP3 for all accounts so I can archive those I need to keep. I would like the tablet and the phone to be able to see and interact with the emails via imap so that when the Master is opened it downloads everything for processing. Do I need to set up each device separately with accounts being either imap or pop3 accordingly? will they all sync together? Thanks for your input.

Whoever designed the Threads feature apparently never used an email program.

• The topmost 'main' message in a thread isn't the newest one, it's the oldest. How the hell does that make sense? • Even if you condense the thread, it still shows the oldest one • As a result, if you sort and look at the date column, it looks completely out of order. I thought it was a bug at first until I realized what was happening. • Replies keep getting indented instead of staying at the same width, which makes long thread subjects impossible to see because they get cropped off and it's just a bunch of blank space. • There's no option to change any of it.

As a result, it's completely worthless to use. Please no talking about editing customization files users won't do or extensions that try to partially bandaid the situation that shouldn't have to.

How could this be botched so badly? Just copy Outlook's conversations view, which is light years ahead of this and does it right. Seemingly there was zero user & QA testing when this was getting developed.

Where can a report be filed so this can get fixed and useable?

I want to open my MSG files in Thunderbird, but with attachments. I have received a large number of MSG files that are so large in size, and my main problem is that I want all of those files in my Thunderbird. Manually doing that took a lot of time plus in some files, attachments were not supported. Any reliable way to open .msg in Thunderbird?

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.

When I receive a junk email, it spends a brief time in my inbox before being moved to the spam folder by the automatic classifier of Thunderbird. In that brief window, the notification system already displays the notification. I found no way of changing that behavior. Is this normal behavior? How to change it?

Hello,

I have this problem. On only 1 PC from 5, with same mailboxes installed and same configurations, on one of the mailboxes, Thunderbird does not accept setting to "not read" the letter. I tried making time to read the letter and it worked for 10 min, and then again stopped. At final, no matter how it is set, when I push to read the message it always read it.

Tried repairing the folder, but doesn't work.

Any Ideas will be great.

Thank you

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?

Firefox on this Windows 10 computer stopped providing an email Send option about 2 weeks ago. I still receive all messages fine, but must use Firefox on an older windows 7 computer to send emails. What can I do? Other internet receive and send functions are still working. The problem is only with email.
