I-Thunderbird Community Forum

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?

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 ?

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.

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.

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?

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.

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.

I've been using Thunderbird for years with little problems. Until now. It won't let me compress as its saying I don't have any space left. Is there any way email files can be deleted to free up the space? I've deleted virtually every application from my drive and it still won't work. Many thanks Paul

When I highlight multiple messages for deletion; it can take up to a minute to respond; when I am working with gmail or proton, the deletion is immediate. When I am accessing Reagan with browser, the multiple deletions are also immediate. Appears to definitely be a handoff issue. Suggestions? I use Thunderbird on 2 win11 os and 2 linix mint 2.1 machines. I only delete and store to local on one machine (win11) ver/build 23H2: 22631.6199.

I keep email tabs open if I am going to have to reference the email for some reason -- shipping product tracking emails, legal documents, threads of conversations that are ongoing. Every so often, Thunderbird decides to open with all of the tabs blank. It's unrecoverable, and I have to search each of the tabs I really needed to open up again after spending time X ing the blank ones.

I've been filing about this bug for years now. Mostly what I get is a bored moderator/mentor telling me why that isn't a priority, and how I should change my emailing behavior. I just lost track of several legal documents and am anticipating working for hours to get them back on top.

I'm very sick of it.

Hi All,

Thuderbird 140.12.0esr (aarch64)

iMac 24Gb M4 Chip macOS Tahoe 26.4

When I request a search through Unified Folders Inbox for 10 email addresses using Quick Filter, CPU goes to 80% or more, and response is 10-15 seconds. Main search appears to be ok. Only add-on was a printer service but has been disabled and problem still remains. In troubleshooting mode, search still causes high CPU, even though I can only search one email address. Just started about 2-3 days ago (around 17-18 June).

Any ideas?

Thanks.

receives no email. sends no email. my server received many emails since then. everything else seems to work. it is not my server as I have Outlook, which received the emails. Only thunderbird is locked-up.

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

I have a new laptop and installed Thunderbird. It shows lots of messages in all the folders, but will not show any messages in the message screen. It just continues to show the opening logo

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.

I own two computers running MacOS 10.15.7 Catalina and have Thunderbird installed on both. Until rather recently, the Thunderbird version was 140.8.1. Then I noted that it was impossible to send e-mails, and soon discovered that the cause was outdated server settings. They could not handle office365, so I installed Thunderbird 148.01 and changed to settings that should be able to do so. This worked very well on one of the computers, the one which has a fast (SSD) hard drive, but not on the other that has a slow (non-SSD) drive. The error message that I get with the slow computer is, surprisingly, the same as I got with the older Thunderbird. But I suspect that the real cause is some kind of timed-out process.

If any of you could explain what happens and tell me what to do, I would be very happy. Maybe I should choose a Thunderbird version somehere between 140 and 148?
