In attempting to address inbox message duplication in Thunderbird (https://support.mozilla.org/en-US/questions/1453812#answer-1666737), I've been systematically deleting thousands of old emails from my inbox, followed by a folder compacting.

Now, many of the remaining messages are unreadable. Most appear to be blank /empty, while some appear as gibberish text. I've tried repairing the folder using the tool in Folder Properties. That may have made the problem worse.

Hello, we are running Thunderbird 128.1.0osr (32-bit) released on 8/6/24. Ever since the upgrade my husband's email has not worked correctly.

Around that same time, he received a pop up within the Thunderbird app asking for donations from Thunderbird. The popup would not go away and my husband lost a ton of his email.

Ever since these two events his Thunderbird email won't work correctly.

Messages since 8/4/24 at 6:32 am DO work correctly. Emails prior to 5/6/23 also work correctly. Any message in the time period from 5/6/23 at 11:26 am to 8/4/24 does NOT work correctly.

We are having the same trouble with the sent items folder.

We use a third party email that we import into Thunderbird and have used the third party email and Thunderbird since at least 2020 and never had this problem.

We can see all the message headers in our email list, but when we click on the email, nothing shows up. It will briefly say "message loading" at the bottom corner, but the email is totally blank. Furthermore, the message that peeks out at the bottom is the last email that we clicked on from the section of emails that does work. It is not changing to the email we are actually clicking on.

For example: lets say we have an email with message header "thank you for your order" received on 8/15. We click into that and it pulls up fine.

Then we go into older email from 7/31. The message header is "hurry sale ends today". If we click on that, it will say "message loading" at the bottom corner. However, the message preview at the bottom of the screen still displays the from/to/subject from the previous email we viewed from 8/15 "thank you for your order" (the message from 8/15 shows as blank though).

Even if we double click the message from 7/31 that we are trying to view, it just pulls up a blank screen. The bar at the top will briefly display the correct message title that we are trying to open, then it just blanks out.

Steps we have taken:

1. In Account Settings/Privacy I clicked to "allow remote content". This made an improvement as prior to this we were having the same problem even with recent messages. We could see one or two messages that had just arrived, then the third message we couldn't see. We have messages set to delete on the server after so many days. So I think it was able to recover the message that were still on the remove 3rd party server.

2. We moved a lot of the emails into archive folders as I thought the inbox may be too large. That didn't make any improvement.

Thanks for any help you can provide. My husband has a lot of really important information in his emails that he needs.

Thunder bird on windows (115.10.1) freezes with a not responding message when a few delete messages are made. Earlier it used to scroll to some random location on the screen. now it freezes for a long while. Is this a bug to be fixed or something wrong at my end?

thanks Raman

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.

This latest version of Thunderbird is garbage. Constantly crashing and you get the this program is "Not Responding". Been using the program for years and have been very happy with it. Now I'm thinking of dumping it.

TB 115.14.0, Win 10 22H2, desktop PC, POP3 from gmail...

I select one of my gmail accounts in TB and click Get Messages. It downloads one or a few emails from gmail and then suddenly the Windows hourglass appears and the banner bar at top of screen which says: "Inbox - (email account)@gmail.com - Mozilla Thunderbird" shows (Not Responding). After ~10-15 sec, downloading resumes normally and all messages accessible.

Happens with all 3 of my gmail accounts and all use same settings: Server type: POP Mail Server Server Name: pop.gmail.com port 995 Connectivity Security: SSL/TLS Authentication: OAUTH2

No TB add-ons installed, Windows Scanning is disabled in TB, running Windows Defender. Lots of free disk space, 16 GB RAM...

Tried TB troubleshooting but nothing found. Have run various Windows checks (eg, DISM and sfc) with no errors and problem continues.

Suggestions?

Hi, Nearly all of the User Interface windows on Thunderbird are tiny. For example, if I open the "About Thunderbird" the window is tiny. Likewise, various windows with instructions that come up are tiny. I have been able to at least read messages and read the settings windows by cranking up the font size but this does not help in general. This feels like a display resolution issue but other programs are fine. So if I change the system display res, I expect other programs to be huge. I have seen some threads on this in the archive but for older versions. I am running TB 128.1esr (I think - difficult to read!) on an iMac running Sonoma 14.6.1. I just upgraded to a new iMac and my previous installation was on Mojave and ran a thing called Theme and Font Changer, which is now disabled (possibly some buried consequence of running that add-on is resonspible). Really would appreciate help!!! Thank you. Tobias

On startup, Thunderbird hangs up for about 2 to 3 minutes. Also hangs up sporadically there after making use of Thunderbird almost useless. This is a recent problem. Have been using Thurderbird for years without any trouble. How do I fix this problem.

I've hit the refresh button 1000s of times to get halfway through my emails I'm still a few months from current it downloads 1-3 emails most of the time when hitting refresh all. And most of the help I found for this stuff is very out of date.

A few weeks ago, I noticed that the contents of my inbox folder stopped displaying correctly. Initially, when I received new emails, they appeared normally in the inbox folder. However, after a few days, the contents of these messages started to disappear, leaving only blank emails. I have created subfolders within the main inbox folder, and those subfolders haven't been affected at all.

I tried repairing the inbox folder, but after doing so, the non-displayed messages completely disappeared from the inbox. I have two POP accounts (let's call them Account A and Account B), and only Account A's inbox folder has been affected.

I would greatly appreciate any assistance in resolving this issue. Thank you!

I am a 20-year (give or take) user of Thunderbird, and it is getting almost unusable.

I am hopeful someone can help.

A lot of context....

My principal account is at Comcast (POP3; normal password), but a consulting gig has caused me to add a Outlook account (POP3; OAuth2). And I think that (along with Thunderbird updates within the past year) are the cause of my issues. And the only circumvention I have found is restarting. And yes, I have a large, multi-decade collection of e-mails in about 100 local folders.

Issues that appear intermittently:

1) Pauses (for instance, while composing e-mails) lasting up to 15 seconds where Thunderbird is unresponsive to keystrokes or other UI gestures. 2) Sometimes there are permanent "(Not responding)" lockups. Also there are times where the address book is inaccessible until Thunderbird is closed and restarted. Restarting is also the frequent cure for the persistent authentication issues. 3) Inability to access address book implicitly or via menu item 4) On start-up, generally both accounts get authenticated, but I keep getting nags to enter the Outlook password - If I ignore the nag, it pops up every couple of minutes. If I enter the password incorrectly, it tells me, but if I enter it correctly the login screen goes away, but login screen reappears within a few minutes. 5) Likely in conjunction with (4) above, I intermittently cannot send e-mails outbound to the Comcast account, with Tbird complaining about authentication; reentering the Comcast password does not help until I restart. 6) If (5) above happens, when I restart Tbird, I have to reenter Comcast passwords, even though I always select "remember password" 7) nstmp folders keep getting created.

Thank you for any assistance you can offer.

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

Hi, Why do I have to click twice in a row on a message in the trash that I want to delete? This is how I do it: The message is moved to the trash and should be deleted from there. I mark the message in the trash and then click once on Delete at the bottom right. A window appears asking if I really want to delete. I then click once on Delete and neither the window nor the message disappears. Only when I click on Delete a second time do the window and the message disappear from the trash. What could be the reason for this and how can I fix it? Thank you for a useful answer. I don't have much experience with IT and Thunderbird. Regards Manfred

I migrated to a new computer with Windows 11 and to the latest TB nebula. I copied the profile folders to the new system and it imported 20 years of email correctly. BUT every connections seems to hang and eventually times out. It almost looks like TB blocked by a firewall. Even checking for updates eventually times out. HOWEVER everything works fine in troubleshooting mode.

I have no add-ons installed. I have no VPNs or additional firewalls. Disabling Windows firewall entirely doesn't change anything. I tried "Make the changes and restart" with no success. I added thunderbird.exe to the exceptions to the windows firewall and even added a rule. I tried uninstalling and reinstalling.

Is there any setting related to the connection that would be different in troubleshoot mode? Apparently nobody has ever experienced this problem, I feel like I'm going insane.

Yesterday, after downloading my emails from the weekend and deleting all of the junk mail Thunderbird suggested I compact my Inbox. I went and emptied my trash folder and then compacted my inbox. After the compacting was complete I could not get any of my emails to load in the preview window or in a new window. I then went to properties and tried the "repair". After that I lost all of my emails back to 5-24-21. Is there anyway to recover my lost emails?

Every so often I get a security message when I try to send an e-mail. Regardless whether I confirm the secruity exeption or cancel it, my e-mail doesn't go through, and I have to send it again.

It is not a great problem, but annoying.

Anyone have any soloutions?
