Thunderbird Community Forum

Others have mentioned this but I'm not sure if there is a fix/anything is being done. The threads are all from previous Thunderbird versions.

I use Thunderbird for work. I have to find specific emails and folders - get to them quick. I am no longer able to do this. It's really distressing.

This is something really basic, that should be the default or else really easy to change.

I'm on a Windows machine and using Thunderbird 140.3.0esr. I've been using Thunderbird since 2003 and never had any problems. Now I'm panicking!

Please assist When I go to send a email,I add scanned Documents as a attachment<but in the email Before I send it,I cannot open the attachments It shows Could not be opened,because the associates helper application does not exist chanhe the association in your preferences I have attemped to do the above,But I need your HELP Thank you Darryl. </p>

I’m on a Mac using the Sequoia OS (not ready to update yet to Tahoe). I recently left Microsoft Outlook, my e-mail client for years, because of all the crashing and when I would update, all the stored e-mails disappeared. I am now using Apple Mail and the export function doesn’t work most of the time. Apple tech support did some things that told me they are automatic backups, but I can’t see them.

I use Thunderbird on an old PC and would like to also use it on my Mac. However, when attempting to import, it starts and finishes in about one second, importing nothing. The files are in .mbox format. What am I doing wrong trying to import these files?

Yesterday, my ameritech.net email stopped working in Thunderbird. I get an error saying it's unable to log into the server. The email account works from outlook, and from a web browser, so I know I'm using the right password. I've tried it on more than one computer and it's only Thunderbird that is having the problem. It's working with my gmail account. Any help would be appreciated.

Hi,

I have transferred Thunderbird to a new computer. It opens fine, but it's looking for me to enter new info all over again.

So it looks like it is not finding the right info in the profile.ini file.

Please tell me how to fix this, and let me know in which folders the email information is stored, in case I need to back up all my emails.

In my Thunderbird email client I have 4 email addresses.

The program is in: C:\Program Files\Mozilla Thunderbird\thunderbird.exe

The Profile Folder in Thunderbird itself lists: zvhtqvg2.default-release-1

But in AppData\Roaming\Thunderbird\Profis lists 2 files: 0jyd0ev.default-release zvhtqvg2.default-release-1

In Windows(C)\Users\ted\AppData\Roaming\Thunderbird the profiles.ini file list the following:

[Install746F856C10C5FA7C] Default=Profiles/0jyd0ev.default-release Locked=1

[InstallD78BF5DD33499EC2] Default=Profiles/zvhtqvg2.default-release-1 Locked=1

[Profile1] Name=default IsRelative=1 Path=Profiles/0jyd0ev.default-release Default=1

[Profile0] Name=default-release IsRelative=1 Path=Profiles/0jyd0ev.default-release

[General] StartWithLastProfile=1 Version=2

[Profile2] Name=default-release-1 IsRelative=1 Path=Profiles/zvhtqvg2.default-release-1

Thank you, Ted

Hi, I am wondering if there is an add-on for Thunderbird that makes it send messages like Outlook without the connection timing out under poor network conditions. Outlook simply holds the message in the Outbox until it has sufficient service to send it. With Thunderbird if there is a poor connection, it's always popping up time out errors in such a case.

I don't find in the on-line documentation any method to--when composing the body of an e-mail message--start new line without starting a new paragraph.

What I want is in a sense the opposite of the non-breaking space. I have read that discussion.

I am asking how to enter a break, without adding the space that is use between paragraphs.

Right after typing my email address and pressing "Continue", Thunderbird crashes. I wanted to give it a try after many years of not using it, but then it crashes right at the start.

Here's the crash report:

Hi, I am a Building Inspector so take lots of photos and email a lot of documents. I try and delete all inbox and save sent items to a local folder on my computer, but my I phone storage still says that they are not actually deleting from the email program and are being stored somewhere. How do I reduce this storage? I can't download any more Iphone updates because of this.

I have installed Thunderbird on a new computer and copied my profile from the old computer as per instructions on the Mozilla site. However on the install on the new computer the LOCAL FOLDERS, sub folders which I use as archive storage do not contain the messages as per the my old computer. The sub folders are named correctly.

I have attached photos of the sub folders from the old computer showing data in the sub folder and also the new computer showing no data.

Please advise how to retrieve the data for the new computer.

I've read the articles on moving Thunderbird to a new computer. My old computer died but I have a full backup and have replaced the Thunderbird directory a number of times according to the instructions to move TB to a new computer. I have even uninstalled and reinstalled TB to match the version on the old computer (140.4.0.0). It comes up and shows over 8,000 emails, but ALL are in the inbox and none of the probably hundreds of folders and sub-folders show up. I have found some of the names in the Profiles directory but they don't appear in the TB window.

Every time I open thunderbird I get a blank screen with this message, 'Edge: Too many requests' over the top of the thunderbird screen. This screen stays on my desktop after I close Thunderbird and I have to change my screen resolution in order to close the screen. Can you help please? Martyn Smith

I installed Thunderbird on a new (used) computer running Windows 11 Pro using the old computer's mail account and password. Thunderbird seemed to connect automatically to the webmail. However, when I click on the email button the program makes me enter my name and password (already entered). Then when I click on next I get - Error Creating Account. What do I do now? Thanks.

I've been searching for a few days for a solution to Yahoo Mail not downloading to Thunderbird, I've seen other people with the same problem, I've tried different solutions, but at this point I've given up. My Gmail is still downloading but I have to check my Yahoo Mail via a browser. What gives? Why did this happen in the first place?

I have Windows 11, I've updated Thunderbird.

None of the hekp found answers the questiin. Any sent email do not show in the folder. There seems to be no route to repair or otherwise corect the issue. Please advise with current accurate guidance

Today when I logged onto my MacBook I found that my Thunderbird desktop application is corrupt. When I attempt to open it states "You can’t open the application “Thunderbird” because it may be damaged or incomplete." Screen shots included.

I last used TB with no issues on Oct 27th.

I have over 20 years of TB emails that I do not want to loose.

I have backed up my profiles folders (there are 3) from >Go>Library>Thunderbird>Profiles

My first question is that I thought there were multiple locations of profiles. One for local. But I can only find the above profile.

My second question is how to I go about re-installing? Should I remove the corrupt application first and and then reinstall? What steps should I take?

Thank you!

Bought a new computer,, loaded Mozilla email added one account which took two hrs to make it in then loaded another account.. the second one came up will all my folders the first one had nothing and does not work I would like to take it out and start all over but dont want to loose the 2nd what can I do to do this. ? Thanks email to answer is [edited from public] @earthlink.net

When I use IMAP/SMTP incoming/outgoing servers, sending message fails: it asks me to enter another password, but does not give me a prompt to enter it. When I click retry it hangs indefinitely. However, if I create an account with Exchange/Office 365 account, sending mail works just fine. This problem occurs very recently, probably due to an automatic update to Thunderbird 140.4.0esr

Any clues and cues would be very welcome

Help me retrieve my inbox and its subfolders. I have used Thunderbird for 9 or 10 years or more. I know how to find Users and the thunderbird profiles but I cannot figure out what to do next. This is a disaster for me because earthlink doesn't save my old messages.

My computer (Surfacepro 6) crashed shortly before this happened. Thunderbird seems to have updated itself at some point while this was happening and suddenly it was asking me to log in. I didn't know whether to imap or pop. I should have stopped there and gotten help, but i was so bewildered that moments before I was writing emails and several minutes later - poof.
