Thunderbird Support Forum

I keep several email tabs open that have topics I am currently working on with clients. Recently they have been turning blank, so I have no idea what they are--I feel I have lost info that I need to do business. Why do they turn blank? I need this fixed ASAP!

Yesterday I downloaded Thunderbird to Windows 10 (64-bit), added my Office 365 (for work or school) account, rocketmail account and iCloud account. I created unified folders for the three accounts. I have downloaded the TBSync add-on with the required CavDev (?) one to connect my iCloud calendar.

After successful use the first few times, now Thunderbird becomes unresponsive within 5 seconds of opening, every time, rendering the program unusable.

Troubleshooting mode does not fix the problem, so I assume it's not the add-ons, nor does starting my PC in Safe Mode (F4 at startup ie no networking), so I assume it's not antivirus.

I uninstalled Thunderbird and re-installed from the website today. All my accounts were there (so I wonder if the uninstall didn't work properly, although I assume that it's just the files left on my computer that the new Thunderbird installation is accessing).

All these attempted fixes leave the problem unchanged: the window freezing within seconds of opening.

Because the program becomes listed as 'not responding' and greys out on further clicks, I have to hard-close the program using Windows, selecting 'Close the progam'. Clicking 'Wait for the program to respond' leaves the screen greyed out, and nothing changes for at least 20 minutes (the maximum I've tried waiting it out). This also means that it does not yield a formal crash report, because Thunderbird does not recognise it has crashed.

On one occasion it did create a crash report, which I submitted. I am not sure what behaviour allowed this to happen, and I have been unable to reproduce it. That particular crash ID was as follows:

Crash ID: bp-41096385-eebe-4ccc-a47e-f76300240417

Any help much appreciated! I'd love to stick with Thunderbird if possible.

I am currently trying to set up extra SMTP servers for additional identities in my e-mail account. I would like to use the Amazon service for this.

However, as soon as I try to send an email with the data provided by AWS, I get an error message:

"Sending of the message failed. The Outgoing server (SMTP) <ses-smtp-server-url> does not support the selected authentication method. Please change the 'Authentication method' in 'Account Settings | Outgoing Server (SMTP)'."

Changing the "Authentication method" did not work either. If I enter the same data in gmail as "Send mail as" (the equivalent to the extra identity of Thunderbird), the connection in the GUI of gmail works without any problems and I can send e-mails via it. So it can't be the data or the configuration of the SES.

I am afraid that Thunderbird does not yet support the newer protocols that SES requires. Does anyone here have any ideas?

Server: <ses-smtp-server-url> Port 587 Connection security: STARTTLS Auth. method: Encrypted password User Name: <username>

MacOS Sonoma 14.4 seems to have broken a number of apps. AFter updating to Sonoma 14.4 I experienced a great number of crashes with Thunderbird, so I completely uninstalled Thunderbird and removed all traces of plists, Application preferences, everything, reinstalled Thunderbird, and added back the two email accounts I use with it.

It now takes up to 30 seconds to start up Thunderbird, after which it happily no longer crashes, but obviously the startup time is unacceptable. I experience the same problem with Typora, and the developers there informed me that they believe the problem is with a Sonoma change that broke WebKit. I don't know if Thunderbird still uses Gecko or if the new version is WebKit. Please let me know if other Sonoma users have reported this problem or if it's just my system.

I have had good success with Thunderbird until this morning when, posting a second email with photos to my wife, I got the message that the server connection timed out. I called my email internet provider locally, suggested to uninstall and reinstall, to check configuration. None of that worked. I modified one setting, the name of the outgoing server, when I checked with the protocols provided by the email/internet local provider. That also didn't help. I'm at a loss.

Thanks if you can help.

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

I have been using T-bird as my email client for years. Just now, a new screen pops up with this message: "an error occurred during connection to localhost". I have 2 email accounts that I use with T-bird. The one is with comcast; it is the account that comes up with the error message. The other account is with Breezeline, and it appears to be unaffected. However, and this is the problem, I cannot send or receive email from either account. I am going to try to send both a hard copy of the error message, and the data from the T-bird program that I am using. Your help is appreciated. Thanks

As of a few months ago, I have been running into situations where my local folders wind up displaying some entries with no title, no sender, and garbled content (see image). Attempting to Repair the local folders does not have any visible effect.

Server is Microsoft Outlook, connected to via SMAP. I'm running Thunderbird 115.9.0 (64-bit) on Windows 10.

I'm also connecting to this mail server with Microsoft's android client, but that obviously doesn't know anything about the local folders so it shouldn't (?) be interfering.

This is Seriously Annoying. If I put something into the local folders, it's because I want to archive it for reference. That needs to be reliable.

Time for me to abandon Thunderbird? Or is this a known issue with a reliable fix?

I've been noticing apparent duplicate messages within my unified folders inbox on my desktop recently.

Looking further I notice that one of my accounts has 'INBOX' as one of its subfolders which is where the problem appears to stem from. When I look at that account in isolation (ie not in unified folders) I can still see the inbox as a subfolder.

The subfolder 'INBOX' appears to be a duplicate of the account's main inbox (it contains the same number of emails), which may account for the appearance of duplicates.

At a guess this is probably related to inadvertent moving of folders. I find that when trying to use the scroll bar (to scroll down the subfolder list), if the mouse strays slightly to the left it will pick up a subfolder and move it unintentionally. This can cause all sorts of problems with disappearing emails and the folder structures showing differently on different computers.

In this case the duplicate email problem only happens on my desktop. On my laptop I can still see a subfolder named 'INBOX' but it shows as empty and I don't see the duplicate emails in unified folders.

It would be really useful if Mozilla could introduce a 'confirm folder move' feature as that would eradicate inadvertent moves.

How do I resolve the apparent duplicate emails on my desktop? I am somewhat reticent to delete the subfolder 'INBOX' for fear of the potential consequences. . .

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?
