I have used Thunderbird for many years and and have loved it. However, recently my "Local Folders Inbox" have been extremely slow (deleting emails, reviewing an email, etc.). I have tried every suggestion that I have found without any change: reducing emails in the folder (down to about 75 remaining), compacting and repairing the folder, deleting and rebuilding all of the msf files and global database, disabling all addons, empty trash and junk, clear the cache, disable hardware acceleration, exclusion in antivirus, etc. It has become very frustrating. Any suggestions would be greatly appreciated.

When i minimize, it starts "eating" ram the computer crashed when it consumed 59GB of ram.. suspect memory leak.. One solution is turning it off after checked for mail...But i kinda want it minimized so i don't have to check by starting it every now and then..

Hi,

Since updating to Thunderbird 140.7.1esr (64-bit) on Windows 11, moving messages from Inbox to any folder takes about 7 seconds.

Details:

Account type: IMAP (Cogeco)

Happens in all folders

Inbox has ~600 messages (not large)

Was working normally before the recent update

Delay occurs every time moving a message from Inbox to another folder

No freezing — just a delay before the move completes

No antivirus changes

Issue started immediately after update

This appears to be related to IMAP sync behavior introduced in 140.x.

Has anyone else reported this, or is there a known regression?

Thank you.

When I first open K9Mail 16.0 or after scrolling to the top of the message list, the message does not disappear from the list after I open a message, select move, and choose a folder. The message will no longer be clickable after I do this. However, it will remain displaying in the list until I start scrolling the message list, at which point the list updates and removes the moved message.

Please fix this bug.

Thanks.

I have just upgraded to Thunderbird 102.15.1 on my laptop and have a problem with right-click menus on folder names.

The menu appears for a brief instant and then disappears. If I move the mouse cursor slightly then it is redrawn and behaves normally.

Is this a known problem, i.e. requiring a further upgrade?

While checking mail in my inbox, I opened, then deleted a message (message 1). As has been happening lately, there was a significant pause between my hitting delete and the mesage going away. Then I opened another message (message 2), and I found that it had the header for message 2 displayed in the inbox, but showed the text of message 1 when opened. Scrambled messages and headers could be a big problem.

I logged onto the mail server (gmail) directly. It showed me message 2 with the correct header, and message 1 was in trash.

To fix the problem, I deleted message 2 on the server, and waited for it to vanish from the headers in my Thunderbird inbox. Then, I copied it back from trash on the server. After it downloaded to Thunderbird, everything was fine, but I wanted to alert you to the issue. Something evidently can go awry on TB's end to scramble headers and messages, and that is scary.

Running TB 147.0.1 with gmail(imap) as the mail server. I have posted twice in the past week about issues with gmail, and I am suspecting something going on at that end. My TB installation is brand new since then; the problems with logging on and staying connected that I reported only went away when I removed .esr, rebooted, and did a clean install of TB.

Please advise if this is a known problem, and if there are settings I can tweak to prevent recurrence.

A bug perhaps:- If I highlight various messages at once (I use shift and arrow) and then I press delete. When i subsequently navigate to any other message I can't read it, instead I see this message until I quit and reload Thunderbird: We're sorry, but we can't display this conversation, because the messages have been moved or deleted. Has anyone else noticed this and, better still, do you know how to work around it. I'm using Unified Folders by the way, in case that's relevant.

Hi I was using TB 142 without problems. When upgrading to 143 ou 144.B4 I have problems sending mails to all users after some times. Usually the first mails are sent immediatly but after around 10 mails, I have very slow response (varies from 5 sec to more than 1 minute and sometimes timeout). Usually quitting TB solves the problem but this is very annoying. I went back to 140LTS and sems to have no longer this problem. This was tested on many diffrent networks. I am running under Fedora release 42

Thanks

For several days now, Thunderbird has been responding extremely slowly to mouse movements or clicks. This leads to undesirable results because emails are suddenly deleted that should not be deleted (due to forced double clicks). Or folders are not opened, or the wrong folders are opened.

The last change was updating Thunderbird. Is this a known bug?

I've been using Firefox for a while, and while there are many things I like about it, it has always been a resource hog. In the past I could get around this by just killing Firefox in Windows Resource Manager and restarting, but ever since getting a new computer an upgrading to Windows 11, it's gotten worse. Every couple of days my computer freezes for 10 or more minutes, I'm having to do a hard reboot ever few days, and I'm even bluescreening about twice a month. I'm pretty sure Firefox is the culprit because killing it will usually resolve the issue.

I'm wondering if there is some way to put Firefox in a sandbox so it does not consume nearly all available memory and other computer resources. It is by far the biggest consumer of resources on my system and I do not want to dedicate 4GB+ of memory to an app that is just showing a couple of web pages and playing YouTube videos.

I have been using thunderbird for a few years now on win 10. Just had to buy a new win 11 system and successfully installed it. transferred my emails, folders and contacts and all seemed to work fine. Now I notice that once I leave it for a few mins, it is unresponsive with just a blue circle where the curser should be. I close it and re open and all is fine again for a few mins. I have tried turning off my antivirus software and disconnecting from the internet but still the same fault. Any ideas please?

a black box appears over the search box when mouse is moved over the tab. Tried in safe and troubleshoot mode. Box still appears only in white I did find an answer previously but reinstalled firefox and the fix was lost. Problem resolved.

Thanks all for looking.

I was happily using TB 78.14.0 on Mac OS 10.9.5 and I switched to using TB 140.6 on Mac OS 12.7.4, and it's now unusably slow. I've tried: troubleshoot mode with add-ons off; compacting folders; removing and renewing msf files; emptying junk and trash. Is there anything else, or is this just a failure or incompatibility of the app? I can't see that there's any antivirus app that might be interfering. Can something go wrong when you export the files from one TB into another? I would be grateful for any suggestions. Tim

Just installed TB for Android on Samsung S24 Fe. Works fine but am unable to exit the application other than forcing phone back to home screen. Have installed on a Samsung tablet and the back button seems to be working OK. Anyone know of any issues with this phone and TB?

Imagine having more than 30 Accounts to be added on a single profile my concern is how will Thunderbird handles file size if it's using one file (MBOX) and if the file has no solution, can I create files and keep mails on them until they reach max size?

I have two installations of Thunderbird on two different computers 2 different locations, both are new installations. Both are on Windows 11. The one at home, works perfect, the one in my second home too except the unified toolbar is unresponsive, whatever I click there it doesn't respond, The X doesn't close the program, the - doesn't minimize anything, just nothing happens, any advise?
