Thunderbird Support Forum

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.

If you give me an email address I will send you the screenshot of my error message.

Or, call me NOW at [removed from public support forum]

Thank You. Marty Straka

I belong to a number of newsgroups where I save technical data from that is in the form of email. 1. How can I save messages, with header intact, to a text file as I could with Eudora? 2. When I start Thunderbird, what email is loaded into memory?

Hello

I have a bizarre issue with attachments.

I open all attachments in their respective programs rather than preview within Thunderbird itself (I have also tried opening in preview but I get exactly the same problem).

When I receive an email with attachments, mainly Word, Excel or PDF docs, I click to open the attachment but nothing happens. If I save the attachments to my computer and try to open it says the attachment is empty or corrupt.

But, if I click to forward the email, I can then open the attachments as normal by clicking on them in the draft email and also then save them to the computer and they open as normal.

I am running the latest version - 115.10.1 (64-bit) and I have noticed this issue for about the last week or so. Otherwise everything seems to work as normal.

Any ideas on what is going on or ways to change this.

Thanks in advance

Reaching my end with defects in thunderbird. I select items in the inbox/index of the UI and it isn't updating the email view pane.

Sometimes I select in the index, it highlights the message, doesn't update and then 10-15 seconds later, the UI does a big update like it had hung on something, and it just ignores my selection completely and selects whatever it wants. This is crazy.

I'll add I have a "unified folder" and despite the 3 accounts inboxes included from accounts configured to never auto update, IT ALWAYS does updates whenever it wishes. Again, this is crazy. Like it can't be supposed to work like this ?

So: Is this thing single threaded ? Is the "unified" folder functionality mature and does it work properly ? Suggestions or pointers to fix or research/test what I see is just flat out poor performance when clicking stuff in the UI ?

I really can't believe I'm questioning the basics of thunderbird.

Version is Win 10, 115.8.1 (64-bit), udpating now but I'd say I have found the basic performance to have tanked since the bug UI change to "modernize" it. Seems to me, without exact data to support that I have been degrading ever since. No updates I've made in last few months have improved anything.

Really don't want to leave but I'm about to try using it on Mac and Linux to compare and at same time I just configured all this in apple mail for the first time in maybe 10 years. This is something I never ever thought I'd do.

Last thought, I use same accounts, on iPhone (Boxer) and many iPads. I don't see any performance problems there so I'm pretty confident this isn't the mail servers.

My sent messages are not being saved-error message says current command did not succeed. The mail server for plvltodd@cox.net responded TRYCREATE mailbox doesn't exist Sent .001 + .000secs

When I search with TB it is not finding all the results.

This is especially frustrating because the main reason I started using TB is because the search on my host's webmail is abysmal. But it turns out that TB search (for me) is even more abysmal.

I am sure this is happening because something is wrong but I don't know how to go about fixing it. I have already rebuilt the global database but that did not fix it. However, the new global database file is about half the size it was before I rebuilt it.

Is there anything else I can do?

Hi,

I have a user who sends me an email to one of my email addresses and it always ends up in the Junk folder. I've repeatedly marked his emails as not junk but that doesn't seem to change anything.

Is there anything I can look at that will help me figure out why it happens, and hopefully find a way to fix it.

I'm on Betterbird in case that matters. I looked thru the release notes and there seems to be nothing tagged with the junk filter.

I noticed this in the X-Proofpoint-Spam-Details email headers: mlxlogscore=764 clxscore=1015

This person seems to be the only person that has this information in their headers. Is it added by the junk filter? Or is it something on the sender's side (he uses an icloud.com and a me.com address)?

Thanks,

L

Somebody thought that it is a GREAT idea to make drag-n-drop cursor a GIANT rectanglular thumbnail of the emails being dragged.

No, this is a horrible idea because that thumbnail covers the target of the drag-and-drop.

Either REVERT this IMMEDIATELY or let us know how to disable and revert to the simple drag-n-drop mouse cursor that does not obstruct the target of the drag.

And in the future AVOID any GUI changes that are not ABSOLUTELY NECESSARY. With these poorly thought through, extremely annoying changes you are only causing damage and aggravation.

Hi, starting with Thunderbird 126.b02 (al least) there are very heavy perfoming issues. Beyond crashes it takes approximatly 10 seconds to open a specific email. Moving to another account is much more difficult: taking itself a much of time it takes supplemental time to open the INBOX.

Despite an Raphael on-dice-graphics I'm running a discrete Radeon RX 6700XT. HDD is far away from being over-lastet or running out of memory

Any ideas? Appreciated. Thx. B.

Im using Thunderbird Beta release. Starting last week, my PC would become extremely slow, to the point it would nearly come to a complete halt. After digging around, I realized it was due to excessively large Thunderbird NSTMP files that were being created. I would delete them and the speed would improve. But then a while later, the NSTMP files reappear and gobble up all my Harddisk again. Part of the issue is the sheer large size of the file, which will consume all available space on my HD, which at present is 600GB. But it also eats up all my RAM so my system slows down til the NSTMP file is fully built.

I use this as imap with Gmail installed on a PC with a 1TB SSD

Today after my pc started slowing again, I started poking around and noticed my main Inbox is massive, 29GB, which there is no chance its that large. All Mail is only 1GB to give perspective

This has been going on about a week.

I tried repairing my inboxes and other folders, but that does not seem to have helped.

Hi, I am trying to login to my emails and after entering my password the following message comes up message comes up. 'Login to server mail.optusnet.com.au with username dianne.hill failed' Can you please help me?

I have reviewed the previous forums on what changes to make to the outgoing stmp for outlook and have implemented them however, I am still unable to send emails. Please see attached for the edit smtp settings I am using. According to the forums these are the correct settings. The only difference is that I don't seem to have the ability to set authentication method to login as that is not an option for me.

What am I missing?

Hi I am having problems with Thunderbird, i’m not sure if it’s to do with a windows 11 update or something else. Thunderbird is not responding also at the start of the ‘not responding’ emails from one of my accounts disappeared and then gradually started to reappear but didn’t get up to date and now just not responding st all. I have tried various things to resolve this, uninstalling and reinstalling Thunderbird, doing this and opening my pc in safe mode, doing this and opening Thunderbird in safe mode. Deleting and reinstalling the latest windows 11 update, reinstalling the latest Thunderbird update. I don’t know what to try next? I read somewhere to delete your profile, after saving it, and getting a new profile but no idea how to do this. Any help appreciated.

Support needs to take their head out of the sand! With the latest release of Thunderbird for iOS it does not work when trying to type a message. The default is "preformat" and trying to change it to paragraph or other does not work. Older version works on my MacBook Pro (2011). My MacBook Air, Thunderbird writing message does not work. Glad I did not contribute money! Oh well must be a way to get folks to purchase Office 365, Outlook?

I need to set up several gmail accounts in Thunderbird. The accounts exist; I can see email by going to gmail's webmail for them. I'm running Thunderbird 115.10.1 on Windows 11.

I choose Tools > Account Settings > Add Mail Account then provide the name, email address, password, then TB validates the credentials with gmail's systems. I get a green light message saying that gmail found the entries. I then provide the appropriate POP3 server name and port address and the appropriate SMTP server name and port address and confirm security settings - all of which were verified and carefully edited when entered. TB then sends the information to google and after an very long delay returns a message saying the attempt failed, probably due to incorrect password or settings. All of the information and settings - including the password which was copied and pasted AND the same one used to log in to gmail webmail - are correct.

Obviously, I'm doing something wrong but don't know what. The error message is so generic as to be unhelpful.

Can anyone help me discover the problem?

Dzień dobry, Chciałbym uzyskać pomoc z odblokowaniem możliwości wysyłania wiadomości, mianowicie prowadzę restauracje i wysyłałem duza liczbę wiadomości z ofertą gastronomiczna i nagle pojawił się problem.

I remember when you could select a range of messages and delete the lot quickly. This is how I maintain my email. For a while now, and still, it takes a bit to sort messages, normally for me sort is by "Correspondent". Then when I select a range and hit delete, I may as well go do something else. Thunderbird goes unresponsive for the long duration. It is a major problem.

I am still using Win10 Pro, system disk is an SSD (1 TB) and the data disk is a normal HD (4 TB). 16 GB RAM, a Lenovo tower. It is not running out of memory, the drive isn't over utilized either. A 15 message delete is slow, try over 100 messages!

All other programs run fine, it is used in electronics design mostly. This issue popped up a while ago and I kept hoping it would be fixed. It hasn't yet. The OS is kept up to date, no other changes. I do compact folders regularly, so indexes should be optimized.
