Thunderbird Support Forum

Hey all!

I recently migrated my hosting and I deleted the accounts on my Thunderbird client to set the new ones with the correct new Hosting.

The accounts are working correctly, but everytime I open Thunderbird, it shows me a login request from the old hosting service (which by the way, there is nothing there anymore, i deleted all the accounts and data).

I already uninstalled and reinstalled mozilla and tried to "fresh start" again, but this problem doesn't seem to go away.

Help is much appreciated!

Hello and Good Morning!

I need to transfer messages from one computer to another. I follow your instructions - export to .zip, file smaller than 2gb. On the second computer, I import the .zip file, the import seems to be successful, then I restart the program and I don't see the imported data anywhere (only Local Folders is created, but it is empty).

Could you please help me? Will be very, very helpful ;)

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.

Good Day,

For the last few weeks, when using Thunderbird on Windows and writing a draft email, when clicking on the button to create a link, the draft email window freezes. This also happens if I use the menu bar Insert -> Links...

All other Thunderbird windows remain functioning, and I can effectively continue working, but the frozen draft window will remain on screen until closed through Task Manager.

This only happens when creating a Link, not inserting other objects, like an Image. This problem also does not happen with Thunderbird on Ubuntu.

I am running version 115.10.1.

Thanks in advance for any tips that could be of help.

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.

I have a Fastmail and 2 Cox addresses on rolled back Thunderbird 102. The Fastmail is IMap and both Cox addresses are POP 3. Cox is transitioning to Yahoo Mail, but we have kept our Cox addresses. I'm getting Yahoo mail web mail and think I should change the existing settings on Thunderbird and not create new accounts, but want to make sure. I saw something about Thunderbird and Yahoo and want to make sure I do it right or should use the third party setting for desktop clients that Cox provided for the transition. For me, the transition has not gone smoothly and I'm pretty frustrated. I am not a techie and any help in getting mail to the 2 Cox addresses landing in Thunderbird and the Fastmail continuing as is would be greatly appreciated. Thank you.

I added a PNG picture as a background to my emails. Instead of a single background picture, it produces a collage (can't think of another word) of multiple copies of the same picture. Any way to just get a single picture?

Since I updated to the last Thunderbird version, the messages in my inbox are deleted after one month if I don't "star" them. I don't think I changed any settings? Can somebody help me with this?

Seems after the latest update Thunderbird will not receive some emails. It has stopped receiving emails coming from some cell phones and some .com emails. Some cell phone emails work and others that previously did do not anymore. I do not understand the random situation. No settings have been changed nor is there any setting to correct this. I even reinstalled Thunderbird.

Any suggestions would be great. Thanks

After the latest update: Every time I send a message and have selected at recipient, the program searches for a cetificate, allthough encryption is swichted off. A box appears for each recipient for about a minute, unless I stop the search (see image). Essentially, the program acts, as if I had selected encryption. This was newer an issue before latest update.

I am trying to do a mass mailing in Thunderbird to about 2015 libraries, with another one to come. I followed all the instructions carefully and generated all the messages and they went into my outbox, with a "send later" command. Then this morning I entered the command to empty the outbox. I immediately began getting an error message that I could only send 50 messages an hour. Feeling like the sorcerer's apprentice, I closed thunderbird, whcih stopped the bleeding. Now I have 1350 messages in the outbox which thunderbird did not try to send.

Fixing up this mess is going to be complicated, particularly with respect to the messages it did try and fail to send (about 750 of them.) But I could make some real progress if I could figure out how to send 50 of the unset messages at a time from the outbox. I have the first 50 out of the 1350 selected right now, but I can't figure out how to get them sent. HELP! Thanks in advance.

Could not find anything in add-ons, settings, or about:config. There is a topic on this site https://support.mozilla.org/en-US/questions/1086884 but I am not able to follow it because there is no add-on or plugin to enable or I cannot find it.

I sent an email with multiple BCCs and no CCs or TOs, I put myself as one of the BCCs.

I did not receive it and I do not think anybody else did as well since I asked a few people.

The email is in the sent folder. I tried forwarding the email from my sent folder to myself as CC, and that worked. I also tried fowarding as BCC, and that worked.

So what is going on? Is BCC working? How can I know for certain? Do I need to foward the email as BCCs to all my BCCs to get this to work?

Thanks for your help.

my wfie sends me windows outlook emails with files that read .eml at the end of the attachment linux 115.0.105 and thunderbird latest, it then reads what should thunderbird do with this file? If i click open with (it defaults to kmail view (default)) if i click on the arrow down i get other, if click on other, I get: celluloid, mpv media player, libreoffice, none of which will open the attachment.

For marital happiness, what do i do? I have tried to stay away from k-whatever. Thank you...b³
