Thunderbird causes my machine to 'hang' from time to time,

1. often for up to a second and usually a number of times in quick succession on each ocasion. Sometimes this happens frequently - say every 5 or 10 minutes - sometimes only after an hour or more since the past occurrance.

2. My machine hangs completely - nothing will work, mouse, keyboard, sound, other apps etc. If I happen to be typing (into any app - including Thunderbird - when this happens, input ceases, the cursor freezes and - if the problem persists for a second or two, Windows reports "[app] is not responding"

3. I cannot be certain, but I believe the problem occurs whilst messages are being retrieved.

This is a very serious problem as it means that I can never leave TB running as the problems it causes are not acceptable.

4. This means I cannot deal with incoming messages without periodically re-starting TB - which is an utter PIA.

I am running Win 11 Professional on a 2-year old machine with 64 Gb of memory. I have run TB in Troubleshoot mode, I have confirmed that the problem occurs regardless or whatever other apps are running (or none) and I have proven conclusively that no other app causes any kind of similar problem.

Looking forward yto hearing if others have had the same issue and what can be done about it.

Hi,

I'm running the latest version of Thunderbird 140.12.1esr on 15.7.7 (24G720) on an M1 processor.

I'm witnessing Memory leak > Thunderbird who usually use 800MB jumps to Gb up to 60Gb

It makes this version unusable.

Here is a loom of the incident: https://www.loom.com/share/0b8e661b42d64d749d80adfd71fd1e04

+ a screenshot

Anyone can help ?

Best Olivier

Hi , I am using the MacBook Pro M5 which is running with macOS Tahoe 26.5 . I have installed Thunderbird mail with version 150.0.2 . After the initial installation with only one account with few mails in the inbox I found the App opening time is abnormally high & is more than 1 minutes . I have removed the mail App few times & re installed it ( even I have re download the app from net again) , but the problem remain same .

I have removed the old folder & files from - ~/Library/Thunderbird/ , ~/Library/Application Support/Thunderbird/ , ~/Library/Caches/Thunderbird/ , org.mozilla.thunderbird from ~/Library/Preferences/. before the re installation & re started the laptop , but no improvement in results .

Also in mail setting references → Unchecked the option - Enable Global Search and Indexer Disable all Extensions and Themes under Tools → Add‑ons & Themes (No Extensions is installed) .

Just to inform that the apple mail is working fine in this laptop .

After all the above trails the results are same , the app once quit & re start - it takes around 1.5 minutes to open after which the app works normally with out any problem . Please suggest if any solution is available for this problem . Best Regards Gautam Banerjee

I realize this can be a macOS issue as the problem appeared when I upgraded to 26x but I'm hoping that maybe there's another way of allowing windows to be moved with a mouse. This issue appears only under tbird and not under any other Apple or non-Apple products.

The new child window(s) opens up in the default location(s).

The issue has survived several OS updates up to the current one. I switched from macOS 15x to 26x in around January 26.

Firefox does not really open any child windows that I could find but browsing windows work as expected.

It says that the folder is in use by some other operation. I tried a Force Quit and a restart and neither worked. Please help.

His OS is 10.13 and his TB is 115.18.0. He kept the old Mini because he was running an ancient version of Photoshop that ran a plugin that is not available for Adobe Creative Cloud.

Robert was a sculptor who did large kinetic work and much of his work is still on that computer.

I am still getting his email on my iPhone, so I don't know what is going on. Unfortunately, I haven't saved his email history on my iPhone so when someone answered a similar problem a couple of years ago, the only place that email would reside is in Robert's inbox on his Mini, which I can't open.

Many thanks for your help.

Been using Thunderbird for a number of years but recently the SSD on my laptop became corrupted and I had to buy a new one and install TB and restore my profiles from a backup.

I have two accounts and switch between them with Profile Manager.

The new laptop is an ASUS Vivobook with Win 11 Home and although TB runs ok the first time, if I close the current session and try to open the other account, nothing happens when I click on TB icon on the taskbar. IF I wait for around 5 minutes then it will run

Checked in Task Manager and cant see any instances of TB running, so any thoughts on what's wrong. Does not matter which order I open the accounts.

I have a Postfix/Dovecot server that hosts 10 of my domains from one IP.

When you open Thunderbird, it checks the domains you have preset. I have two. This happens immediately, especially if there is no new mail on the server. Everything works fine.

If you have other domain mailboxes open, and I have eight more, and you click the inbox on each one, Thunderbird stalls at the fifth mailbox, regardless of the inboxes' selected order.

tail -f /var/log/mail.log - confirms this.

I have reset or modified everything I can think of. My server is not throttling Dovecot.

This must be something internal to Thunderbird, possibly related to only using a specific mail server IP for all domains.

Google AI suggests assigning a unique local IP alias to each domain on my server so Thunderbird thinks it’s talking to 10 different machines. This seems extreme.

Any solutions?

I see others are having this same issue with no resolution in sight.

The company I work at is unable to print anything through the print preview in Thunderbird. The current work around is to download, open, then print the file.

Does anyone have any further information on this subject besides going through separate avenues to fix the problem?

Thanks!

I've been using TB for years. Lately I can be browsing the Inbox when the contents will disappear and I get a message saying something like no messages found. After about 30 seconds the Inbox is displayed again.

TB never used to do this and it is similar to Firefox refreshing the screen which it also never used to do this.

Also how do I get from the Beta version to the standard version?

If Thunderbird startup is stopped before tabs are loaded, they are lost. The tab fields at the top of the screen remain but they are empty. Evidently, tabs are stored only in a temporary location. This is a very annoying bug. Is there a way to recover them?

It is my custom to run spell check after typing an email. Today, sudenly, the write window hangs when I click on spelling. Does not happen in troubleshoot mode. I have no extensions installed and default theme. I did try disabling hardware acceleraton, but did not help.

Yesterday all workd OK, and thre have been no changes to the computer snce.

We are facing issues with Thunderbird mail application.

Incoming emails are not being received in Thunderbird. Thunderbird is running very slowly and frequently becomes unresponsive. Sending and receiving emails is taking a long time. We have already restarted the application and system, but the issue still persists.

Kindly check the mail server settings and Thunderbird configuration from your end and advise on the necessary action to resolve this issue as soon as possible.

Your prompt support will be highly appreciated.

Whenever I do anything with email I get a message "not responding" which causes a delay for a few minutes before it proceeds This occurs with almost every action Open email, delete email, browse a different folder (eg Inbox to Sent) it suddenly started happening yesterday

This post is more for posterity than asking for a solution because all similar topics ended up being Avast antivirus interfering or something less nefarious.

In my case eM client started having this problem first, then I switched to TB, but the same issue here. Of all places, the best clue was found on [[Linux mint|https://forums.linuxmint.com/viewtopic.php?t=213352]] forums. It was a permission problem. Right click on C:\Program Files\Mozilla Thunderbird -> properties -> security. I did two things and not sure which one did it, but they pretty much achieve the same. ...

The Users group in the list only had read permissions so I gave it full access to the folder and checked the option to set the same permission changes to all subfolders. I also added my own personal user to that list and gave that full permissions. Oh yeah, also changed owner to myself from whatever default windows group was there before.

Now, do I know the full repercussions of doing this? No. Pretty sure this just created a security hole inside my C drive, but... I don't really care at this point. If I had to fix this again, a solution might be to instruct TB to store the the email files somewhere else rather than where it is installed itself (somewhere less locked down than Program Files).

When creating a new email and entering a recipient address, Thunderbird automatically suggests addresses after typing a few characters. However, in my case the auto-complete suggestions take about 10 seconds to appear after I start typing.

I am using Thunderbird version 149.0.1. My settings under Settings → Composition → Addressing are as follows:

☑ Local Address Books ☐ LDAP Server ☑ Automatically add outgoing recipients to: Collected Addresses Initial Directory for Address Book: Last Used Directory

I would like to understand what kind of search Thunderbird performs when auto-completing email addresses.

Also, if anyone has experienced the same issue, how did you resolve it?

Any insights or advice would be greatly appreciated.

Whenever I start Thunderbird, I get messages such as that some mailboxes cannot be compacted and some filtering cannot be done "because another operation is in progress". Why is this? How can I prevent it? It is a nuisance having to go and chase down and correct the filtering that has not taken place.

When I try to delete mail from Deleted folder (even if there is just 1 email), the thuderbird gets unresponsive. Same when i try to select few emails (headers) for deletion or moving to another folder. Running on Windows 11
