I have a large amount of email stored on an IMAP server. Would like to reduce that by moving most or all of it to a local disk drive. Am looking for a (hopefully simple) guide to doing the transfer. I don't see a Local Folders entry in the left-hand pane; not sure if that matters. (Presently running TB 115.10.1 64-bit on Windows 10 and 11.)

Hi, I want to copy my Thunderbird profile in windows 10 from old computer to a new one, whan I go in Roamng>Thinderbird>Profiles> it shows total size 32 GB. I tried deleting in the Thunderbird application some emails but total size in prifeles reduced only by 1 Gb, I gues that some very old emails even before 2012 are stored somwhare in Profles but I can not locate. Whan I go to Inbox.sbd it shows 8,5 GB but whan I enter in the applicatin shows much less size?

The Reply command no longer shows when I want to send an email back to the person that sent it. There is a note at the bottom of the email that says: A unique identity matching the From address was not found. The message will be sent using the current From field and setting from identity Vince Hunter < omni232@telus.net> Can you give me instructions in laymans terms to fix this bug and return it back to the way it was?

Is there a way to get your email password within Thunderbird? I'm trying to add TB to a new computer but it is not taking the password that I thought I was using.

Hi, I don't know what I did but suddenly I only have the chat screen (which I have never been in, screenshot attached) and can't get back to my normal Thunderbird window where I see all my emails. All functions in the drop-down menus don't work, I can't get into settings or anything. What do I need to do to get back to my emails?

I cannot login to Thunderbird. I have a Telstra Bigpond email account. I have set it up for imap using the Telstra settings. My password is correct but it is not accepted and I cannot login.

Good Morning, I donate to Thunderbird on a regular basis. I have had bought for me a new Lenovo Laptop. I have managed to install Thundebird OK but my address book has not moved over to my Laptop. Why has this not happened & could be so kind as to instruct me on how to resolve it. Iam 86 & registered as disabled & my Computer skills are a little limited. I have tried to import the addres book but have not succeeded. Regards Peter Alexander Carr 0744 393 5419

Have other computer running W10 Tbird using POP3. New laptop W11, I had mistakenly set up Tbird as IMAP. Didn't notice it for months until I needed to clean trash on email provider server. Then noticed all my trash on the W11 Tbird disappeared. I'm messy & like trash so want to keep it on my computers. How can I change the W11 machine from IMAP to POP3 without losing anything? Another question, is there any way to combine the sent emails from the different computers?

Long time user, but suddenly I cannot send email on Thunderbird. I receive message: "ELNK003. Error code 308. Verify email address in Account Settings". All appears OK to me, but I cannot send , but only receive. Thanks, Michael Opitz [edited] @mindspring.com Cell: [edited phone# from community support forum]

Thunderbird keeps crashing on startup with msg: Crashed Thread: 4 Breakpad ExceptionHandler

Exception Type: EXC_CRASH (SIGKILL (Code Signature Invalid)) Exception Codes: 0x0000000000000001, 0x0000000000000000

Termination Reason: Namespace CODESIGNING, Code 2 Invalid Page

So, it looks like the the app "signature" is corrupted. How do I remove signature and and correct for valid signature. Thanks.

Such an annoying problem with current version 128.5.2esr. On one notebook with Windows 11 Hone I install the latest version (no Thunderbird previously installed), works fine.

One another notebook with Windows 11 Home existing Thunderbird freezes. After startup it just hangs, using so much CPU, that the battery is half drained after 30 minutes. Then reinstalling does not help. The same issue persists.

I read that uninstall does not remove the profiles and that cause the issues. Is that possible. Feature request. Also it would be fine to have the option to remove the profile on uninstall, so the non-tech savy user has also a chance of using this client.

Hi, I don't remember exactly from which release it started, but for a couple of months, quick filtering has not been working properly. For example, when typing the sender's name, the results show emails from other senders, and the sought name can be found in the 'Copy' field or in the message text. However, quick filtering works as before, fully correctly in Troubleshooting mode 😳 Attached screenshots with quick filtering results shown when opening TB in 'Normal' and in Troubleshooting mode.

Quick Filter is still extremely slow on the newest version of Thunderbird (128.1.1esr). I asked a question about this previously. It was reported as a bug (see links below) and it says in the report it was fixed, but the problem still seems to be there in the newest version. Any idea when this will be fixed, or if there is anything I can do about it?

There is a thread about it on reddit. https://www.reddit.com/r/Thunderbird/comments/1e6hryp/quick_filter_is_super_slow_in_128/

There was a bug reported, and it is listed as closed (solved). Here is the bug report thread: https://bugzilla.mozilla.org/show_bug.cgi?id=1908761

Thanks for you help.

I was sorry to see that the 128 Nebula release did not fix the longstanding problem that Thunderbird is very slow to load in Sonoma, and has been since the Sonoma release. This is with 128.0.1esr (64-bit) on an Apple M1 Mac Mini with Sonoma 14.6. I have the same problem on a 2018 Mac Book Pro running Sonoma with an Intel chip. The problem is NOT manifest on a 2013 Mac Book Pro running the last release of Big Sur. In all 3 cases the same email accounts are loaded, so it is some interaction with the OS. (I previously reported this for Tbird 115 under Sonoma, with no resolution.)

Specifically, when I start Tbird 128 on the Sonoma M1 the window comes up in about 2 seconds but contents are blank. The contents don't fill until about 30 seconds. This makes it painful to quickly hop into email to do something, so I am resorting to Apple Mail when in a hurry. If I do the same on my 2013 Big Sur machine, it's 2 seconds for the window to come up and 8 seconds for the content to fill. Upgrading from 115 to 128 did not change this on any of the machines.

None of the enhancements of recent releases are of sufficient value to compensate for this, so I wish the team would focus on ensuring speed on all platforms. Is there any clue what is going on?

Ever since I've been upgraded to Thunderbird 128, I've been experiencing constant hangs. I'm running the latest versions of Thunderbird and Windows 10. My antivirus software is Windows Security.

This issue seems to be most acute whenever Thunderbird checks for new messages. Thunderbird's CPU usage jumps to between 25 and 30%, and memory and disk usage also skyrocket. Thunderbird freezes completely, and everything other program that's running at the time is slowed to a crawl for several minutes minutes. Troubleshoot Mode doesn't help.

Any suggestions?

Thanks.

Hello, I recently bought a MacBook Air 2024 with G3 chip (Sonoma 14.6.1) and used Time Machine to transfer all the data from my previous Apple MacBook Air from 2015 (Mojave 10.14.6) to the new computer. This also transferred my Thunderbird profile folder. It has the extension .default and an 8-digit combination of letters and numbers in front of it. Since the old version of Thunderbird no longer ran on Sonoma, I installed Thunderbird 115.15.0 and then opened Thunderbird on the new MacBook Air. Since then, Thunderbird has been taking an extremely long time to open (much longer than on the old MacBook Air with Mojave. Yesterday I updated to 128.2.0esr, which didn't help either. I deleted a deactivated extension in the add-ons, so that there are now no extensions, only a few dictionaries that I deleted as a test, which also did not bring any improvement. Switching off the hardware acceleration, clearing the cache and changing the themes did not improve the situation either. With the themes, I can only switch between dark, light and system theme - automatically. I checked and made sure that Thunderbird actually loads the .default profile folder from my old computer as the active profile. However, Thunderbird has also automatically set up a second profile with the extension .default-release. Could this be causing the problem? My active profile folder has a size of 15.21 GB and the new .deault-release profile folder has 18.6 MB. Both profile folders are located in Library/Thunderbird/Profiles I am quite desperate and hope that someone can help me. Thank you very much!

Why is Thunderbird on Windows so agonizingly slow and unresponsive after recent updates? I've checked my memory, CPU, disk usage, network, everything. I've rebooted. I've tried it on multiple networks. Same thing - agonizingly slow and unresponsive. I've been using Thunderbird for over 22 years, and it's always been wonderful. Now, it SUCKS! What happened? Does anyone know of a better email client for Windows? I've contributed to T-Bird several times, but I can't support these latest updates. It's barely usable now. Help!

Hello!

Similar to Ludas question of 11/11/23: There was an update about 10 days ago, after which the Quick Filter started working terribly slowly: 1. Even before I have written the entire keyword (including email address), Thunderbird starts "thinking" and crashes (Not Responding). 2. After some time, about 1+ minute, results appear. 3. I went through Safe Mode on Windows and Troubleshoot Mode on Thunderbird - no change.

This account has ~52k letters, IMAP. For accounts with a small number of letters, there is no such delay.

This is essentially the same problem as https://support.mozilla.org/en-US/questions/1430726 . I am running 128.1.0esr, and the problem surfaced recently. I installed 128.0.1esr (replacing 115.13.0) on July 31. and the problem might have been re-introduced there. I have not researched the version numbers, so I do not know why I went from 115.13.0 to 118.0.1esr.

Here is the problem. I want to see all of the mails with a certain string in the sender field. After I have typed the first character in the filter field, Thunderbird goes into a "Not Responding" state, and I see a spinning blue circle. After I have entered the entire string, it takes a while before TB becomes responsive. When TB becomes responsive, I can delete all of the selected messages (in less than a second). But when I then remove or change the string, TB takes a lot of time before becoming responsive again. Wayne Mery posted at the end of that other archived thread "115.9.0 has a patch related to quick filters which may help." Has that patch somehow been regressed? Thanks.

Hi to all, after the latest update to 128.1.1esr (64-bit) the quick filter is very very slow and hangs the PC (WIN 11, 16 GB RAM and SSD) for 10-15 seconds. Thunderbird no longer responds and this happens all the time, also with different machines. The version before the update was just fine. Anyone with the same issue? Can you give me some hints/solutions? Thanks, Antonio
