Thunderbird Support Forum

So running thunderbird 115.10.1 (64-bit) and more and more issues:

• the app keeps getting non-responsive for long period of time, to fix this I have to force quit the app.
• at times when composing an email the app freezes where no typing occurs for seconds or typing is very slow or after typing awhile the text suddenly appears.

Seems to be happening more and more trying to figure out how it can return back to it's rockstar state when it was <99 version.

any help would be appreciated.

emails load very slowly or the app stalls & doesn't respond. Often I have to tap twice to open an email. When deleting an email it can take a couple seconds especially when deleting multiple. I can hit the delete button several time & have to wait several seconds for it to finally catch up. This has been happening for a few months now & is getting worse. Sometimes the pictures in the message load one at a time. It was working right, then one day it started lagging & hasn't been right since.

Just switching between inboxes can cause up to a 10 second delay with Thundebird "not responding" with the spinning wheel. It has been like this for the last few laptops I've had and through all the updates and I am getting ready to call it quits. I did a performance recording of me just clicking through the different folders and then it locks up on one. You can see it here https://share.firefox.dev/3WlrRi9

I am using a primary gmail imap account, an office 365 imap account, and another imap account from an ISP.

On Win 10 LTSC, CPU: 16 x 11th Gen Intel(R) Core(TM) i7-11800H @ 2.30GHz @ 2304 MHz 10240 KB Cache, MEM: 65277 MB, 60% (39120 MB) free, GFX: NVIDIA GeForce RTX 3080 Laptop GPU 16192 MB

Every few days, the index pane of some folder gets corrupted. Repair (right-click, Properties, Repair Folder) fixes it. Then a few days later this repeats, with a different folder. I have three IMAP accounts and this occurs on more than one of them.

Any suggestion for finding and fixing the underlying problem?

Today, most of messages have suddenly disappeared from my TB inbox, leaving only the most recent 105 out of approx. 18,000. I have not performed any operations (compacting, archiving...) that could have caused this.

I immediately invoked the 'Repair Folder' command, which did not resolve the problem. Further investigation revealed that the 'Inbox' file ('Profiles' folder) actually contains only 105 messages - seems like the 'Repair Folder' truncated the file!

Fortunately, all the messages are still on the server. My question: Is there a method to 'force' reloading of the missing messages?

Thanks, Ray

I get this Error message when I try to send emails from my outlook email address in Thunderbird. Basically asking me to enter a Password to login to office365 server ! My Password is correct, and has not been changed recently.

Any ideas please ?

A while ago, I had to work offline so I had TB download my Gmail account messages. Now I no longer want these messages to be stored locally, because the Thunderbird folder is up to 10Gb, so I unchecked the box in Synchronization for 'Keep messages in all folders for this account on this computer'. I was hoping the TB would subsequently purge the offline folders, but apparently not. Is there a way to clean out the folders without affecting my online Gmail folders as in Inbox and Sent folders?

I am using Thunderbird 115.10.1 on Windows 11. T keeps deleting my saved passwords. T takes a very long time to load. There are no saved passwords and I enter them all with the options to save. I check the passwords in Settings and they are all there correctly. When I next run Thunderbird it may or may not have them still saved. I check the Settings and they have gone; so I enter them again and they are saved OK. But then they are deleted some time later. I cannot see any pattern in the failure. I wonder if there is a problem with the outgoing server setttings. All the passwords are lost whether imap, pop (Ionos), hotmail or yahoo. Is there a way to clear out my profile or is this a problem with this T release. it did not happen until about 1-2 months ago. My profile is on a local NAS. Generally T seems to be quite unstable ; I get Not Responding too often.. Thanks

Using 115.10.1 and POP on Windows 10 Pro (v. 22H2) with just the Windows built-in virus protection enabled (but App or Browser Control is disabled). Platform seems stable, no evidence of nefarious services noted in task manager.

Realized the emails in InBox from a couple of days ago (and going back decades) were blank or had mismatched headers to content. Figured an index problem. Ran the Repair under 'InBox' folder Properties, and only a few of the most recent emails remain - all duplicates of which I had sorted into other folders.

All the other folders are fine - just my InBox got wiped! Looked in the Thunderbird folder under profiles and saw the above captioned with a time-stamp that captures the approximate time this went down - occum's razor. I did not initiate any update to Thunderbird.

Walking on eggshells and very nervous, we're talking thousands of emails, what is the recommended recovery of the InBox (after I attempt to backup what I have left). Thanks!

Hello

Yesterday there was update in Thunderbird and went well. But today, Thunderbird suddenly asking for credentials and then it went totally blank as in screenshot. There is nothing at all. But incoming mails are still showing up in windows notification and it can be opened as new tab of Thunderbird. I have been searching the possible cause and solution from forum and internet, but no luck. Can someone please help me about this ?

how can i stop thunderbird from interacting with windows defender anti virus scan? when ever i download or delete emails i get a few seconds of "not responding " and the whole computer is non responsive. i used to be able to turn off real time scan in security and it would work for a day and then windows would enable it again. now since the last upgrade windows isnt allowing me that option any more. solutions?

Hi. When replying to an e-mail, Thunderbird has started to place to input cursor in the TO field instead of the message text field (in this case it should be before the answered text).

Any ideas? BR Johnny

Here in Jan 2024 suddenly TB will no longer connect to any hotmail or outlook..it says I have to enter a new password but I have not changed my password and can get onto them if I go directly to that site. Any suggestions?

I'm trying to use Thunderbird to access my work emails directly. They use Outlook Office 365, which I can use the webmail version of just fine, but a year ago they upgraded to Oauth2 and MFA and for the life of me I cannot get any version of Thunderbord to work with it anymore. I can send an email, but I can access any email on the server. Weirder still is the error console message suggest the program thinks I cancelled my password entry;

"Loading failed for the <script> with source “chrome://global/content/netError.js”. neterror:128:4

NS_ERROR_ABORT: User canceled primary password entry"

Thunderbird on my top of the range Win11 laptop was working perfectly until it self-updated to 115.10.1 a couple of days ago. Accessing messages already in the various folder is fast as usual. Unfortunately anything like deleting, downloading a new message is excruciatingly slow : several seconds to click and delete in the inbox. Several seconds to access a message just downloaded. The first time it happened I had a whole bunch of messages deleted because the I kept clicking when I saw no action. It seems to me like it has problem updating the messages in the inbox. Very painful for something that was working so well.

I am asked to get a new password from my mail server (AOL) every day when trying to send messages. Have to log on to AOL, ask for app password, enter at Thunderbird. DAILY!
