When I open Thunderbird (Mozilla), my files are not current. In other words, the most recent emails, probably since the last time I used Thunderbird, in my file folders are missing. I have tried changing the server settings but I think they are correct. Please be patient with me, I am unfamiliar with all the terminology, etc. Also, when I first enter Thunderbird, it does not recognize my password. A window opens with the message "Login to server imap.postoffice.net with username john.fn@usa.net failed." That message also appears when I click on Get Messages. Thanks for any help.

I exported my profile to an external drive, then reset my Windows 11 PC. The resulting file is a zip file. When I import, the import starts, then stalls and gives an error. The error log is incomprehensible to me. How can I not lose my local folders and messages? I tried unzipping and importing that folder, but another error. I need help! Ideas? Thanks.

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

I am now getting a spinning wheel with annoying frequency while using/trying to use Thunderbird on my MacBook Air 2017 running Monterey. Everything was fine for the first 6-9 months, but over recent months the spinning wheel has appeared more and more frequently while I'm trying to read mail, answer mail, scroll through messages, etc., etc. Now it comes up every few minutes and delays me doing anything for about 15-30 seconds at a time. It's really frustrating. I recently ran Onyx, which was designed to clear cache, etc and make everything run smoothly. But the only program it required me to quit before it started was Thunderbird. Is there some cache or something I need to clear on a (semi-) regular basis to keep it working at a reasonable speed without this godforsaken spinning wheel interrupting everything? Thanks for any/all your help.

For some reason, I am getting message that the Certificate for server is not valid (etc.). I can not get or send my emails as of this morning. Is there something I can do to resolve this issue?

This is a continuation of a problem I reported earlier... https://support.mozilla.org/en-US/questions/1442170

Updating to version 115.9 did not solve the problem. Today I updated to 115.10.1 and the problem persists. Thunderbird is also recommending that I update to version 116, but I don't even see that listed on the Mozilla web page for the change logs.

Thunderbird 115.10.1, Mac OS 10.13.6, iMac 20-in Early 2008 model.

I can open Thunderbird and check mail in multiple accounts. If I close the Thunderbird window (but leave the app running), CPU usage will eventually jump up to more than 100%. It does not happen right away, but could take 10 minutes or so. Currently it is at 115% processor usage. If I open the Thunderbird window again, the processor usage drops to under 8%, then drops again to below 0.4%.

HI, I have TBird 102.15.1 64Bit installed on several different PCs and laptops. On my main Laptop I checked the Roaming\Thunderbird folder properties and found the following: Size on Disk: 35.8 GB Contains 253,172 files and 1,533 Folders. Is their anyway I can reduce the size? My TBird seems to be running slowly and occasionally stalls. I do not want to switch back to Outlook client program, I am not a Microsoft supporter. I do know I could move mail to local folders but would that mean I could only access them from one machine? Thanks.

I get a message like this every time I start Thunderbird. The topic came up last year but the conclusion was along the lines of "...this problem will be fixed in version 128" but it was never clear whether or not the User followed Mozilla's support replies or what they had to do to clear the email message from Thunderbird. .....Well I'm running version 128.1.1esr and the problem still exists.

My questions:

1. What is Thunderbird trying to do? Compact individual email files? Compae from ct the whole Thunderbird Profiles folder?

2. Is the problem the size of the Profiles folder or the overall size of the hard drive the Profiles folder resides on? What is the Hard/solidstate drive is the maximum?

3. Is the problem related to the amount of Free Space left on the Hard/solidstate drive or is the issue the number of individual files?

4. Is the issue related to the number of Thunderbird files and/or folders OR is it related to the total number of files and/or folders on the hard drive?

5. Is there a limit to the number of sub-folder levels that Thunderbird can navigate?

Thank you.

Have always set up accounts so they download all messages to hard drive.

Since 3/27/25, it is as if it never officially logs the downloads as downloaded, so it downloads each day as if it hasn't been done since 3/27/25, marking all of the messages since then as new.

File is very large so want to try fixing without deleting entire file.

Tried the 'repair this folder' but that didn't work.

Having trouble identifying the exact folder on the hard drive to delete since there are several different accounts in the Thunderbird setup.

I think it started to happen with Version 128.9.0esr | Released April 1, 2025. It is very simple to reproduce: 1. Start TB. 2. TB downloads new messages and continues to do it every 1 minute according to the setting. 3. In 10 to 20 minutes, it hangs. I have to force it to close and then restart it to check my email.

I believe it started to happen yesterday.

Is anyone else experiencing this?

Thunderbird, quite suddenly, stopped getting my email; Both on my account and my wife's account at the same ISP. I spent more than two hours on the phone with the ISPs help line trying to resolve this issue. They also use Thunderbird at their help desk, and the agent I talked to was familiar with your program. She (the agent) was not able to replicate the issue on their system. We then tried to set up a NEW email account. I carefully entered all the info needed for a new account, following instructions from the agent, then hit the 'Test' button. I got the following message onscreen: "THUNDERBIRD FAILED TO FIND SETTINGS FOR YOUR EMAIL ACCOUNT" The answer to the original issue suddenly became very clear - Thunderbird cannot, or refuses to, connect with the email server, therefore NO EMAIL. We tried everything in her toolkit to resolve the problem to no avail. We finally tried UNINSTALLING Thunderbird (and the Maintaince program). Once Uninstalled, I used the Registry Tool on CCleaner to remove any entries in the registry referring to Thunderbird (there were several), then restarted my computer. I then downloaded and installed a totally NEW Thunderbird program. When I ran the Thunderbird again, I found all my account(s) info was still present, and Thunderbird was still unable to find the server. I'm at my wits end trying to resolve this issue, and REALLY HATE to go back to Microsoft OUTLOOK to get my email. Anybody got any ideas??? Any help would be greatly appreciated. (Signed) Proteus

Thunderbird gobbles up too much of my SSD space!

How can I prevent this from happening?

I'm using Thunderbird 128.2.3esr (64-bit) Safari browser Version 18.0 (19619.1.26.111.10, 19619) Macbook Air M2 15" running OS 14.7

See attached screenshot

I have used Thunderbird for years without issue. In the last 2 days, it keeps crashing on one of my laptops (fine on the other). I sent a crash report, but I can't reopen Thunderbird. I tried both quitting and restarting. I shut down my computer and restarted it. I tried updating by downloading the latest version, but that didn't work either. I completely uninstalled it, reinstalled it, and it worked for a few hours. Now, it is back to the Crash Report.

Any suggestions? I love TB and don't want to switch to something else.

I've been using Thunderbird for years and never had any major problems until a few days ago. But ever since you automatically installed Version 128.4.2esr on my HP desktop running Windows 11, all I can get from Thunderbird is a blank screen unless I go into Troubleshoot mode. Subsequent automatic installation of Version 128.4.3esr did not help.

I'm running Sequoia 15.1.1 on an M1 Mac Mini. Never had problems before. TB 128.6 0 esr.

As soon as it opens it crashes.

I have a lot of unopened files in a pop mailbox, going to try and remove them.

It seems to still work on my iPhone. Any ideas?

I M get this working. I'm in a panic. Please help.

Hi I’m a very grateful Thunderbird user, for at least 10+yrs - and its always worked for me. I have done some pretty regular donations as well, to express my gratitude. On Wed my Thunderbird seized up on startup “Not Responding” and after about 5minutes of waiting I killed it with right hand top x. I have one imap and two pop accounts, plus about 7.2G of filed local mail The size on disk of my <profile> is 9.6G My connection to the mail server imap.sonic.net is a DSL ~ 1Mbits For the last two weeks, the writing emails, and saving has been a bit jerky – I assume having I’m Windows 11 latest (i7-9750H CPU @ 2.60GHz ram 16G.) with a C: drive 256G and d: 1000G. I have C:\Program Files\Mozilla Thunderbird - and been on the update channel, though not beta. D:\usr\a\n\AppData\Roaming\Thunderbird\Profiles\<MyProfileName> I copied the profile to a NAS for safe keeping. I ran through https://support.mozilla.org/en-US/kb/troubleshoot-mode-thunderbird

https://support.microsoft.com/en-us/help/12376/windows-10-start-your-pc-in-safe-mode

and for all same result on startup – seized up. I reinstalled Thunderbird Ver 128.4.3esr (64-bit) – seized up. I created a new profile – and starts ok I started using “thunderbird -p” and choosing profile and “work offline” to not pull in the pop account. I copied in the old profile 10G, deleted contents of imap – still seizing up, So I started judiciously deleting older .sqlite though didn’t keep track initially – and then was able to startup, though sometimes also went into being seized up. I went through local folders – folder properties – repair folder. I still have the orginal 10G that was seizing up - so I could do some debug if useful.

I asked bout this a couple of weeks ago but didn't get a response. Perhaps I asked under the wrong heading. I'm not the sharpest tack in the box when it comes to these things. Over the holidays I prepared many emails to send afterwards. I created sub-folders in my drafts folder. I sent the emails OK, but then I couldn't delete the folders I created in the drafts folder. Not only that but the folder icons in Drafts turned from yellow to purple and they did that in all four of my email accounts, even though my storage of emails was all in one single account. When I right click on the folders I don't get the option to delete and the folders won't allow being dragged to trash. Also one of the folders suddenly disappeared with all of the prepared email in it. Can you help me correct this condition? Thanks.

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.
