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

My inbox has disappeared withe the latest update. Replaced by instructions for setting up my account. Having connected to the existing configuration, next instruction is to click on 'create account' - but there is no such box on my screen

In a world where respondent's often draft messages about a new subject by lazily replying to messages on an old subject, does anyone find Threading helpful? Why is it now the default.

After View/Sort by/Unthreaded then propagating that by "apply current view to all folders." All folders do in fact sort by unthreaded. But if I create a new subfolder it defaults to sort by threaded. Please, is there anyway to entirely disable Threading?

I've created a global Inbox for all my E-Mails Accounts. Normaly this Inbox should include all E-Mails. But there is no E-Mail shown at this point. What can i do to fix this issue. As workaround: I have to click on each Inbox to get the E-Mails of these Accounts.

TB 102.6.1 (64-Bit), macOS, DE locale

TB macOS with GUI on extras "Filter" edit lacks scrollbar in sub-window thus making amending / editing of filters almost impossible on the macOS GUI of TB. This mishap was introduced in TB 102.6.x only recently, I presume.

Please consider correct and fix asap.

Question: How to reasonably edit the textual config file for TB filters in cases like this?

I think at some point I was able to send a private message. Or maybe it was just a reply to a private message that was sent to me. I remember something about clicking on a person's picture.

Thanks is advance for yoiur help. SweetTasha

با نصب اپلیکیشن ارسالی چه امکاناتی به گوشی همراهم افزوده شده و چگونه می توانم ترجمه گر یا ترانسلیت را زودتر به کار بیندازم تا دیگر نیازی به پرسش های پی در پی از شما نباشد . لطفا پاسخ مرا به فارسی ارسال کنید متشکرم

Thunderbird’s connection to one of my gmail accounts failed today.

I removed the account and then tried to add it again to Thunderbird.

When logging in using a Google generated App password, I receive the following message:

"400. That’s an error. The server cannot process the request because it is malformed. It should not be retried. That’s all we know."

OAuth2 is in place, and I’ve carried out all other recommended checks I can find on your website. My other Gmail accounts are working fine.

Please can you help? Many thanks.

My thunderbird works okay, but when I select emails from imbox folder to delete it takes too long. I researched to find the problem and the only option I found was to add an exclusion to the profile folder on my windows security antivirus. Now I can select emails from the imbox and delete them without a problem, but my concern is if I will be vulnerable to virus.

Yesterday I tried the 115 (Supernova) and I was disappointed because of the toolbar on top of the TB window: I think that you should let the user choose where put any toolbar, and I didn't find the way to move in its "classical" place (not at top but below the menu). There is a way to do it? And if not, please consider to give it as soon as possible.

I have spoken to my ISP and its confirmed, as have I, that I can log on to its website and successfully download my emails so the problem "must" lie with Thunderbird. I am not very technically inclined so would appreciate some advice please, thank you. My ISP technical person (at iiNet Australia) did say they were receiving a lot of phone calls today about email and "blamed" it on changes to Outlook? If this helps. Regards.

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

When I delete 1 email, it happens quickly. When I delete 5 emails, it takes about 10 seconds. When I delete 40 emails, it takes 2+ minutes, when I delete 100+ emails, it takes 7+ minutes. What's going on? Seems to me emails, no matter how many I delete, should be deleted very quickly. What can I do to speed up the delete process?

Thunderbird has changed one of my folders. This now has a different icon (see snip) and I cannot delete it as there is no option. Is it something that I've done and how do I correct it please. Many thanks

The latest version of Thunderbird changed the top menu, and I see a "Get Messages" button, but can't find "Send Unsent Messages" as a function anywhere. I've tried customizing the menu, and I've looked through older help discussions for any ideas, and I've prowled through the settings menus and can't seem to find it. I've also tried right-clicking on things - no joy. I have a message waiting to go out in the Outbox, but no way to send it except Redirect.

Thanks in advance, for any help or ideas!

I still have v102 on my PC. I have read and see where there are a lot of problems with v115 - messages from users. So if I want to keep v102. How long will it be good? Is there a cut-off date that I will be forced to get v115? Is there someone knowledgeable with Tb that can call me and walk me through getting v115 set up like v102? I am not computer literate enough to be able to do that on my own. Or a way to get simple "step by step" instructions? Trying to read all the updates is way over my head. I am an 85 yr old man that simply wants to be able to read my emails without having to re-learn how. I've been using Tb and Firefox every since I can remember. Years and years. Can someone help? I can furnish email address and/or phone number if needed.

My friend has been using Thunderbird for a long time. Recently I installed her new PC and restored her account profile using the profile folder on her old PC. So far so good. The problem is that her mails are not organized in folders on the mail server but she has a whole collection of folders in her Thunderbird mail client and is concerned about loosing her mails if the new PC (or the disk) would crash at some point. Of course she could just re-install Thunderbird after fixing the crash problem and sync with the mail server, but then the folder structure would be lost. First I considered using a back-up program to keep a back-up of her Thunderbird profile using cloud storage. My second thought (should have been my first thought...) is that she already has a back-up, namely the mail server. The ISP does a better job than any local back-up program to keep her mails safe. Only the missing folder structure remains a concern. So here is the question: if I change the setting to sync all folders with the mail server, what will happen: 1 - the folders in Thunderbird will disappear (only the folders, not the mails) because there are no folders on the mail server 2 - the folder structure from Thunderbird will be mirrorred on the ISP's mail server. Which one is it?

I desperately (sobbing here) need someone to hold my hand and walk me through this!!! I uninstalled the newest version (115) and installed the previous version (102) because of an outgoing mail problem. It gave me a warning that the newer version changed my profiles and it's not compatible so I downloaded the new version again. The import screen doesn't look anything like what it says in the help files. I don't have an option for importing from a previous version.

Please rescue me. I run a nonprofit and I have deadlines and meetings next week that I was supposed to make arrangements for and I've been dealing with this for almost a week.

I've just installed TB 115.6 on my MacBook to see if I like it better than Apple Mail. There is one thing that seems weird to me. Fonts are displayed larger in the Read window than in the Write and Reply windows.

These are my font settings: Default font: Helvetica, size 14 Composition, HTML Style: font: variable width, size: medium

Now if I send an e-mail to myself the font looks larger once I receive the message than what it looked like when I was composing it. And then if I reply to this message the font becomes smaller again in the Reply window.

The font in the Write window has the exact same appearance as in Apple Mail where I also defined Helvetica 14 as the default font. So my suspicion is that the fonts are somehow scaled up in the Read window. But why? And how to change it so that the same font looks the same everywhere?
