This is not a question. It is a statement of issues. I recently bought a new computer and tried to install Thunderbird on my new system. The installation went fine. The setup was one problem after another. Thunderbird required multiple attempts to connect with Outlook and sync my account. Next, I tried to import my contacts. Thunderbird failed numerous attempts to sync contacts. I finally had to manually import my contacts. Then spent an hour manually cleaning up my contacts. Thunderbird seems to have randomly assigned field names. (Names imported as numbers or dates) In addition, it imported contacts without associated data. (No email address, phone numbers etc.) After all that, Thunderbird would not allow me to use any of the contacts. The address book is there, the contacts are there, but it would not reference the address book when I tried to send an email. I had to go to the address book, copy the email and paste it into the to: field. Next, I tried to create events and tasks. First problem, all calendars were disabled by default and no option was offered to enable the calendars. I spent another 45 min. trying to find a setting or something to enable the calendars. When I finally got them enabled, I spent another hour trying to get Thunderbird to create events and tasks. Thunderbird will not create either. I spent far more time than is rational to create each event and task. When I completed each attempt, Thunderbird trashed them. No event or task was ever created. At this point I uninstalled Thunderbird and wrote it off as a bad idea.

Folks, I am not new to this. I have been using similar apps since their early days. I know how to install and setup these apps. I am very familiar with the problems that may be encountered. And this far worse than anything I have seen in a long time. I do not know what is going on at Mozilla, but they have got some serious problems to work out. I will steer clear of Thunderbird for now.

When I receive an attachment in an email, I have the option of opening it, in this case a PDF. Then the attachment is properly displayed, and one of the options given is to print the attachment. When I select print, I get a progress gif that just continues to spin; nothing gets printed. I can open the PDF with Adobe and print it so I know the PDF file is intact.

Help.

Dear Team After Updating from 102.15.1 (32Bit) to 115.28.0 (32Bit) I can not connect to the provider "pop.hispeed.ch" anymore. Ping pop.hispeed.ch (on CMD) shows normal raction of beeing reachable with a "reply from xxxx.". I am on Windows 7 SP1. I have checked several times all setting POP and SMTP, switched off Firewall, uninstalled virus scanner, and and and many more (all knowledge found on internet..). Pressing the "Get Message" button in the upper menue bar shows no raction when pressed. The icon "Get Message" on the left side of the button "+ New Message" results in a none moving blue status bar at the right bottom of the window. After a while with the message "timed out.. ".In the settings "Config Editor.." the values of "mailnews.tcptimeout" are set to "300", and "true". I am using TB since donkey years with many many eMails. Are the lost? Thank you for support and help, Andy

'thunderbird' Windows 10 has been locking shortly after powerup. Simultaneously instead of updating my email, Thunderbird has been pulling down the entire mail server file. How best to recover?

All of our email accounts are down will not receive nor send, we have tried the troubleshooter with no success, we even removed the lates Window Update without any improvement. We have several emails and all are affected. [edited] @centralsystemsok.com [edited] @centralsystemsok.com [edited] @centralsystemsok.com [edited] @centralsystemsok.com

Please let us know what is causing the issue? You cannot email us and let us know because it is nor working, you can email at [edited] @gmail.com or call [edited from public]

In the past week or so I have noticed that some emails disappear from one inbox on my Windows 10 PC. I have three Thunderbird accounts (call them A, B, and C), and the emails only disappear from box A. It seems completely random, and furthermore they only disappear on my own PC. My husband has an identical set-up on his Windows 10 PC, which also includes the boxes A, B, and C, and the messages do NOT disappear there. I can also see them on my iPhone and two iPads, and they do not disappear from those. I have tried forwarding them to myself from my phone, and while most of them did show up in the A inbox on my PC, I have noticed that some of them have now disappeared again.

This is incredibly frustrating, because I do most of my work at my PC. I thought I needed an update, but TB says I am up to date (128.8.0esr (32-bit)). It can't be anything to do with the server, because it is so specific: one inbox on one PC only. There doesn't seem to be any special pattern--some have attachments, some don't.

Many thanks for any suggestions!

'''Hello! When I delete an email in any of my accounts all the accounts go blank ~ no messages show ~ and the screen announces "NO MESSAGES" or some such. I have to quit and restart to get my messages back.

Am I doing something wrong? Suggestions...? Thank you!'''

Dear support team, I've the following issue with calendars in Thunderbird. Was on latest ESR version, an upgrade to latest version 136.0.1 (64 bit) didn't fix it: When I started Thunderbird, suddenly most of my calendars where no longer visible. I figured out by trying to add a new calendar it only (re-)appeared when "offline mode" (caching) was disabled. After changing the setting calendar.registry.[id].cache.enabled to "false" the calendars showed up again.

Could it be some kind of bug or could the calendar storage be corrupt? How can I fix it?

Many thanks in advance for an answer!

Kind regards, H. Bruecher

Dear Thunderbird:

I have used Thunderbird for years. I click on Attach to add images to my email. To check the attachments, I would double click on each one and it would open in my Microsoft Photo Viewer for Windows. However, now instead of opening the image, I get Adobe Acrobat Reader Home page and no image.

Has something changed in Thunderbird ? Or is there a simple setting I can change with your coaching ?

Thank you for your help.

When I run Thunderbird, my download speed is around 278 Mbps. When I close Thunderbird, my download speed jumps to 500+ Mbps. I am running Windows 11 and cabled directly to my Xfinity modem. Is this expected performance for Thunderbird? Is there anything I can do to improve my performance when running Thunderbird?

Hi,

My trash refuses to stay deleted. I delete it and close Thunderbird. The next time I log in, it's back in the Trash folder. This has been going on for over a week.

I have had Thunderbird for years so I know that it isn't in my settings. What is going on?

When I right click on a document [Show More Options/Send To] Thunderbird email I get the following notice: There is no email program associated to perform the requested action. Please install an email or, if one is already installed, create an association in the Default Programs panel. I've been using TB for multiple years with zero problems, this started when I recently reloaded Windows 11 from scratch (due to a bot virus issue). I have reloaded TB 3 or 4 times. I have also tried creating an association to MapiMail which hosed my Send To link. I had to import a new Send To link from my wifes PC after restoring the registry entry for MapiMail. I have always used the 64 bit version, so the 32 bit version is not for me. I am out of ideas? Anybody else have this problem?

message filters only work sometimes. when i click on run now nothing happens. sometimes this works, sometimes i have to walk away and come back, but right now nothing works. i compacted folders, updated firefox, waited, and waited, nothing.

Hello,

I use Thunderbird 128.5.2esr with xubuntu 24.04.

All of a sudden (I haven't changed anything) thunderbird hangs completely after a few minutes running. The process does not react at all, I have to kill it. Thunderbird process is then stuck on 100% load.

Already testet (with no success):

• Troubleshooting Mode with deactivated Addons
• Disabled Global Indexing (with deleting global-messages-db.sqlite file)
• Waiting for 20min (in case thread/process is running a long time)
• Reboot OS

I have no idea what the issue is. Does anyone have ideas? Thx, Hugo

I have tracked down the situation where my Internet download speeds drop from about 598 Mbps to around 267 Mbps after I open Mozilla. I am running a desktop computer with Windows 11 (updated) and Edge and Chrome. I am hardwired directly to my Xfinity modem (no WiFi connection). When I close Mozilla, my speed goes to 598 Mbps, and when I open Mozilla, my speed drops to 267 Mbps. This seems excessive and unacceptable. Are there any settings or anything to adjust, not to have Mozilla be such a drain on my system?
