I'm having issues with Thunderbird trying to forward an email with images. The email has 2 PNG images attached and when I click on Forward I see 'Attached Message Part 0 bytes' in the Attachment section. If I send this email and check my Sent, it is indeed 0 bytes and I get an error message stating "This attachment appears to be empty...". This is also the message the person who received said email receives.

I did some searching and seen one suggestion to check your account options to ensure 'Compose messages in HTML format' is enabled. I do have this enabled. In terms of forwarding style, I have it set to 'Inline' which I believe is default and is preferred.

So far this seems to only happen to PNG images. If I forward a DOC, DOCX, PDF, etc. I have no issue with it being attached. If the email contains both a PNG and DOCX, the DOCX will be attached and the PNG won't (with it being replaced with an 'Attached Message Part 0 bytes'). I looked for a JPG email and I was able to forward it properly, so it does seem to be PNG related.

We have a problem with labels in Thunderbird Mail. In our company, we use several computers and have assigned 9 labels in different colors to mark emails according to where they should go. However, on some computers, some labels do not work. On 6 computers, all labels work fine, but on the remaining 3, there is a problem with some of them not working. In this case, marking an email on one computer does not show up on another and vice versa. Please help us solve this problem, as it is very bothersome.

Another question is whether it is possible to add more than 9 labels, for example, using letters instead of numbers?

Today both our email accounts stopped working. One is a gmail account and one is from plusnet. Both accounts worked yesterday. I have made no changes or altered anything on the machine or Thunderbird. I have found that a TB 115 patch was applied at 09:17(UK time) 28 Nov. This correlates to when the problem started. No new emails downloaded. - checked directly with email providers and mails present

Then I received various messages: 1. Cannot authenticate. Shut down TB, rebooted router. then 2. Time out (received from both email servers.) and occasionally exceeded conection limits.

No problems accessing emails via outlook. What is the problem please.

Hi

I have quite strange problem with Thunderbird. I do not know when it has started but a quite long ago.

I use complicated structure of directories in my inbox (directories with subdirectories) and I have prepared significant amount of filters - I do not know if that matters. At this moment filters are disabled because I wanted to get know what exactly happen. Scenarios:

1. TB checks for emails every 1 minute, and they appear in INBOX.

A2. Press Message Filters -> Run now (on Inbox) A3. Emails disappear from Inbox A4. Emails appear in directories. Directories are marked with bold font as contain unread messages (but should be blue with star) A5. Click directory - directory become marked with yellow star and blue font as contain new messages A6. Do not read anything. Click another directory - yellow star disappear, font become black

B2. Read some emails B3. Press Message Filters -> Run now (on Inbox) B4. Emails appear in directories (but sometimes after 10-15 minutes). Directories are marked with yellow star and blue font as contain new messages (even if all emails were read when they were in Inbox directory few days ago and I replied to them)

I cant find out when which scenario works. But IMHO both are wrong. Email should be moved to another directory, appear immediately and (only if it is new message) directory should be marked with yellow star.

I presume it is somehow tied with email server but I do not know how. What can I do to avoid this problem?

I have faced with the following bug linked to messages displaying in thread in any section of Thunderbird (i.e., Incoming messages). See the screenshot - there is just thin white stripe instead of text of the message. This bug repeats only for some random messages. Restart of Thunderbird resolves this bug temporarily.

I am a long time Thunderbird user and have not seen it slow down this much. I try to check mail and it takes an inordinate amount of time. Then, when I think it has received the new mails, I click on one and that takes a long time to display the message. If I send a message, putting the sent mail to the sent mail box is a long wait, it may even fail although I could see it on Gmail in the Web browser. If I switch to a new folder, I see the message on the status bar telling me sending login information, and the wait continues. Why does it send the login credentials if it is not closed only to look in a different folder?

I am using version 115.5.1 on a gigabit connection. This happens on my laptop, MS Surface Studio Laptop, and my desktop computer with more power. The laptop uses WiFi and the desktop is cabled Gigabit Ethernet.

It is pushing me to look into alternative e-mail clients, I hope I can remain with TB.

I deleted a tag and then added a new one (Settings/Tags/New...). It ended up inserting the new tag in the position of the deleted tag (ie. the new tag shows up in place 4, where the deleted tag was, don't know if that's relevant).

The new tag does not work. Whenever I use that tag it shows up and then disappears. Any ideas how I can fix this? Would deleting all the tags and starting again help or make things worse? I've seen similar threads here but they've been archived so I'm starting a new one.

Basically, each account is receiving every email, but these accounts are for separate purposes. I need to know if this is something that I have done or is it the result of the upgrade to 115? The issue described has only been occurring for a week or so and may have started after I added Thunderbird to a new PC. All three home computers are behaving the same way and I'm using IMAP.

My junk email folder has over 4 million messages. There are hundreds of the same message from the same time.

I came across this post from a while ago. https://support.mozilla.org/en-US/questions/1169324#answer-991184

How do I find the Junk and Junk.msi files so I can delete them?

I upgraded to 115.3.1 from 102.15.1 this week. I do not understand the large increase in version number, but I have not done any searches. I have a number of complains with this new version.

1) I want to move one message to a Local Folder, and I get the message at the bottom "nn messages moved from Inbox to Tr.ash". The one message I wanted to move remains in the Inbox, and I have to move it again. When I try to move them again, the folder displayed is NOT the one into which I had just tried to save. I have no idea if any messages were moved from Inbox to Trash, and I have no idea how I would find them.

2) The font size in the window is smaller than it was with 102, and there is blank space on the right. Is there a way to increase the font size?

3) I read one mail message and I process it (delete it or save it in a Local Folder). Most of the time, the next message in the Inbox is opened. But sometimes the window advances to a message further down in the Inbox, and I then have to go back into the Inbox to access then next message I was planning on reading.

I am running Win10 22H2 with TB 115.5.0 (64-bit). Total Message Count works fine; I then restart TB and TMC does not show although the TMC option still shows as checked. If I un-check, then re-check TMC, the Total Message Count again shows. Please refer to the attachments for visuals.

Hi all!

Few days ago Thunderbird start consume 100% and GUI freeze. After restart program/OS, GUI works for few seconds (3-5) and freeze again. I've try to run program with --headless option but still it consume 100% CPU. I've delete cache directory and it didn't fix a problem.

HI

I use Thunderbird on 2 platforms: PC and MAC.

Both are updated to the latest version.

The MAc version have an annoying problem:

It autocorrect almost all words in a crazy manner: 1. It capitalise letters middle of the sentence. 2. It doubles letters 3. It adds space between the first letter of an word and the next word it glue it to the previous word.

I am placing here an example: WE Aare P artof EU

instead of

We are part of EU.

This happens only in Thunderbird so it is not a platform problem. I unchecked the autospelling and autocorrect but this behaviour still happen. Only on MAC. In the same time on PC platform I don't have this problem.

What can be done?

After the last couple of Thunderbird updates, I have been experiencing a really frustrating issue that I can't seem to resolve.

Only when I receive emails from one specific recipient and I go to reply to them, the font size is suddenly really large, and the spacing between new lines is huge.

Even if I set the font options to the same as if I was replying to a different recipient or creating a new message, it still appears really large.

What's worse is even if I make all these adjustments and get the font size and formatting looking okay, the actual sent message is even more out of whack and has all these spacing problems.

Does anyone know what might be going on? No other mail client I use experiences this issue whatsoever, and this issue is only occuring with this recipient.

All my emails come to an Inbox in Thunderbird. When I choose one to move to a separate folder to keep, the inbox contents flips to some point that I don't require, and I then have to scroll through to the point where I took the email I was storing again, often hard to determine. It is random , and if the email I want to shift is on the current day, it seems to behave, but when I choose to move one from a few days ago, it is hopeless. It is time consuming, and annoying, and I can't see the point of it. Why is this happening, and how can I fix it please? It usually flips back to a point earlier than the date I am working on. Weird, and has only done this since one of your last updates, and always stable in the past....For a new addition to the program it is so inefficient. Thank you

Hi, please help, we have an O365 mail account and in Thunderbird we have POP3 protocol set up, authentication via OAuth, one email address is used on multiple PCs. The account is set up so that messages stay on the server and individual users have the same emails and everyone deletes what they need. The problem is that still, after a while, a window pops up for login, authentication to O365, even if we put the login credentials in memory, this is very annoying and annoying :( Sometimes it also happens that the account completely logs out and no message pops up. O365 are set up as recommended from this site. Thank you all very much for any advice.

115.4.1 is terribly slow. When stuff is going on in background like downloading or filtering, I cannot use the interface to select messages or folders. It is very annoying. I can only imagine that when I archive 1000 or more messages every 6 months, that the system is going to choke.

Dear all, I am Thunderbird user for almost a few decades now. Since upgrade several weeks ago, my Thunderbird became slower, and, also started to work not as before. Now it is, after few minor updates up today, 115.5.0 (32-bit) version. The main issue, beside slower speed in showing messages, is it does not mark some messages as read when selected. When I scroll selecting unread messages to read/show them, some of them are marked read as before it did, but some of them stay unmarked in spite of multiple times selecting them and holding them selected. This happens regardless of setting “Automatically mark message as read” options Immediately on display, or After displaying for 1 second. In most cases it happens with last received unread message. Last time I remember such erratic behavior was decades ago. I tried to switch off and back on that option, then restarting program, but nothing changes in it’s behavior. Please advise. Thanks in advance, Zoran

Hello, After update Thunderbird quick filter became very very slow.

If you type in quick filter field two words. At the beginning is being shown random results not connected with typed in words. Then in 30 seconds or later are being loaded correct results. Not possible to use like this. It's local search on normal PC (with CPU AMD Ryzen 5 PRO 4650G, 24GB RAM) filtering must to work fast. Could you fix that issue?

Thank you
