After Update 128.8.1esr installed on 3/19.2025, I cannot receive or send messages. Worked fine in the morning on 3/19 and after update I get nothing. I have an AOL account for my email. I can get my email by going through the AOL internet site, but nothing through Thunderbird. The previous update was 128.8.0esr installed on 3/7/2025, and that worked fine.

Go to the settings, general, fonts and colors and see text is black and background is white. Yet when I return to inbox text is white and background is black. Why is that the case?

Last night (9/23/2024), Thunderbird began presenting a screen (see attached) requiring me to sign in to contine to Mozilla Thunderbird Email. At the top of the screen is a "Sign in with Google" line. However, there is nowhere to sign into anything. My correct email is displayed but no entry for a password.

Clicking "Next" takes you to an Error 400 screen. There is no "Close" button and the only way out of the screen is to hit "Esc," which takes me to my Email account. After a short bit, the screen refreshes back to that " sign in to contine to Mozilla Thunderbird" screen. After one or two more uses of :Esc, I can get back control of my laptop.

Meanwhile, Thunderbird is frozen--mail doesn't update, and any attempt to use T-Bird returns me to the sign in cycle. Win 11; TB ver, 128.2.3esr (32-bit); server security imap.gmail.com, port 993, outgoing server smtp.google.com, authentication OAuth2. I've accepted cookies and javascript and closed my VPN. can't figure what to do next.

Running Thunderbird 115.10.x on Windows 10 Pro 22H2 on an older Samsung Note 9 Pro 15 w/ an 8th gen Intel i7, 16GB RAM and an aftermarket 1TB SSD w/ over 660GB of free space. I have emails going back to 1997 in the Sent folder (16K sent emails). While running Thunderbird 115.9.x earlier today, I noticed I suddenly could not delete emails out of my Inbox. The following error message was displayed:

The messages could not be moved or copied to folder 'Trash on [username@domain.com]' because writing to folder failed. To gain disk space, from the File menu, first choose Empty Trash, and then choose Compact Folders, and then try again.

So I did that to no avail. I then tried to delete messages out of other folders as a test (Sent, Drafts, etc.) figuring I could simply move them back if successful. Received the same error message. Closed all applications and rebooted the laptop as it had been running for several days. Same error message.

Did some research which all told me to delete the Trash MBOX files (including the .msf file). Did that, same result. Launched in Safe Mode, same result. Created a Trash.txt file, removed the .txt file extension and relaunched Thunderbird. Same result. Compacted all folders and relaunched. Same result.

If I backup the current folders and restore from them, I'll get the same result. Anyone have a new idea or set of instructions I can follow?

Thanks!

Hello Mozilla I have Windows 10 pro My last update of Thunderbird resulted in bad function, the former Installation worked not really fine. As I found out Windows showed me two Instances of thunderbird , the new one and an older 115.18.0 I tried to deinstall the old instance of thunderbird usind standard deinstall. This left me with some of the old thunderbird still in the sytem which I cannot deinstall. How can I get rid of these remainders to have a clean fresh installation of thunderbird?

Best Regards Wolfgang

I recently add and embarqmail.com account. incoming "mail.centurylink.net" outgoing "smtp.centurylink.net" It downloads fine but when i single click no message is displayed or double click new window opens but message not displayed. Have had this same problem when installing thunderbird on new computers and just would up using another program. I also have two gmail accounts that work fine. Any suggestions? Thank you

Thunderbird will not start because the first visible startup action is the popup window: "Please enter your Primary Password". Unable to create a password for the initial,first time re-start of Window if on old machine, option was to avoid this. How to fix? ...so I can set and set and use it.

I installed Thunderbird 136.4 (64-bit) today on a new windows 11 Pro PC. I created 4 - POP3 accounts. The 1 gmail address downloaded all older emails from the servers, but the 3 TDS email addresses only downloaded a couple of months of emails. I can't find a setting that will find and download older emails. I checked the online TDS accounts and they have years of emails on them. Anyone else have that problem? Is there a solution anywhere?

I've just resumed using Thunderbird, with a new installation on a new computer, after a long period of having only my ISP's web interface. I'm having a problem with adaptive junk filtering: it thinks everything is junk until I tell it otherwise.

By default, it leaves putative junk messages in the Inbox, but displays a yellow ribbon above a junk message's preview with "Learn more" and "Not junk" buttons. In this configuration, having it assume everything new is junk is just a nuisance.

But eventually I will finish training it, and I'll want it to move junk to the Junk folder automatically. Then this behavior will be a disaster.

Using made-up numbers to illustrate, suppose I get 1000 messages per day. Of these, 998 are from addresses it recognizes, so it knows that 993 of them are junk and 5 are legitimate, because I've received email from those addresses before, and I've told it what to do with them. That leaves 2 messages which may or may not be junk.

It should leave those messages in the Inbox, preferably with some kind of warning, and let me decide whether they are junk or not. Instead it's going to move them to Junk, and I'll never know I got them unless I review all 995 new messages in the Junk folder... which would defeat the whole point of having a junk filter.

Is there a way to make the junk filter default to "not junk" when it doesn't know? I've looked at the configuration dialog, and I don't see one.

One day I tried to send an email, and it failed. This just happened suddenly without me touching any of my settings. When that happened, I researched reasons and have tried everything. It's an outgoing server error. I tried changing it to what my email provider and the internet says it should be, but nothing works. I even called Spectrum, and they said I needed to contact Thunderbird support.

I use an AOL email account and Thunderbird on my Mac. In Thunderbird, the junk mail folder - which AOL call "Bulk Mail" for some reason - has moved to the Trash folder and I can't get it out. It's a Thunderbird problem - if I go onto my account at AOL.com, everything is normal. How do I get it out? I've tried cutting and pasting it, creating a new folder...nothing seems to work. I don't want to empty the trash in case I no longer have a junk folder at all

Hi All,

Two days ago, my Google calendar sync stopped working. I tried to add them again, but now, for a change, I can't see events at all, even though Thunderbird plugins theoretically got access to calendars. Should I wait for an update? Is this a global problem? How can I solve it?

Thank you Mariusz

When Tbird first began it was easy to see which folders were Imap and which were local. That distinction disappeared a while back and I still had all my imap folders but no indication of which were which. When I want to access them the popup menu did show "gmail" (since that is my email domain) and the imap folders there. But when I go to create a new folder it does not show up in the imap list even though I want it to be an imap folder.

How do I create/manage an imap folder in the current Tbird?

I have changed my Windows 11 font and want the look and feel of Thunderbird to be the same as this. I have tried all the suggestions I can find, but none seem to work. How can I do this?
