After several years of working perfectly,For no reason, I am getting this message when trying to connect to Xfinity email server

"  Login to server mail.Comcast.net with username t_m_f@comcast.net failed."

I have set all Comcast server settings to the default. Going directly to Xfinity email works great . So it must be something wrong with Tbird. I also uninstalled & reinstalled Tbird. This is frustrating !!!!!!

Windooze 11. TBird 152.0 installed on June 20th. Now it seems like TBird is not displaying HTML emails properly. They are displayed but not at the beginning. The first line is sometimes just the bottom half of a sentence in the email (if that makes sense). I can't scroll back to the beginning. If I go to outlook and display the same email it displays fine.

Did something change in 152.0 to cause this?

Thanks, Ed Mazurek

I cannot send messages from any of my accounts after migrating to Greenby. I have tried to setup their outgoing server as per their instructions but it does not work. They have a AI tool which I keep going round and round in cycles

I have about a dozen accounts with over 50 folders, most with a matching filter. About 100k messages, taking up about 1G of disk space. All but one account is merged under my Inbox to have fewer duplicate In/Draft/Sent boxes eating up window space. I'm using 152.0.1 (aarch64) Release branch on a Mac OS X 26. All are POP accounts on a DreamHost server.

At some point it started to show the draft message on every email, which means on incoming as well. I've had this phenomenon for years.

Recently filtering has started to not automatically run on some emails forcing me to run the filters manually. I've run the repair folder options which does not seem to make any difference.

Since switching to macOS 26 it also does not allow me to move Thunderbird child windows, they simply show up on the default location. But that's for another ticket.

After Thunderbird 152.0.1 Windows x64 lost its mind:

* my main calendar
* not allow recreation from backup data
* would not load profile

I had no option but to remove and reinstall.

Local Folders has 4 non-removeable folders Drafts - XXxxxx, Sent, Trash and Outbox that were not there in the past 20 years.

I've been using TB for many years, and without warning, when it tries to down load my mail from the Proton mail server, it says it can't find the folder "Inbox". I've tried to "repair" that folder a couple times unsuccessfully. I've restarted the TB program a couple times, but nothing changes. The error shows up on the bottom "instruction line". I've gone through all my settings and find nothing amiss. Not sure where to go from here. -- Just noticed that I had about 80 emails in that Inbox folder that are now missing completely. Normally, I move read emails to there respective folders, and leave important ones in the Inbox for followup. One significant note here, is I'm still using Win 7 premium. So far it hasn't been a problem. Thanks a bunch, Gerald

I'm trying to move from Windows to Linux without downloading all my imap messages again. What I've tried: 1. Install tbird on Linux, create new profile. 2. Close tbird. 3. Using Linux file manager,

 - delete contents of new profile folder
 - copy contents of old profile folder into new folder
 - delete Compatibility.ini in the copy

4. Open tbird with -p (profile manager)

I've tried twice with different results. The first time at step 4 I started offline. Thunderbird opened will all my previous tabs open, except that all the internet tabs reported connection failure - as expected. Under account settings, both local folders and my gmail account reported the correct (new, linux) path. When I went online and completed the gmail OAuth dialog thunderbird reported an inbox summary folder error, and deleted all the imap mbox files. I closed and restarted tbird- which failed with a crash dump. the terminal window reported successful minidump creation- the file manager showed the minidump file at zero size.

I repeated the process (recreating the original unmodified profile). This time at step 4 I started online, and tbird never opened- it generated the crash dump immediately.

Two questions: 1. Is it possible to transfer an imap profile and avoid re-downloading all the old messages? 2. What am I doing wrong that I'm getting the crash dumps?

Thunderbird is not responding. Xfinity is working just fine I need help resetting is there any way I can speak with a person? I am totally bogged down caring for my partner with dementia. I am able to go to my settings, etc.

I've had issues with google and microsoft, changed passwords, now I get credentials messages when Bird tries to get email. I know its because of my password changes but can't fix it. (I edited this because I said authentification before instead of credentials)

Hallo, ich habe gesehen dass ältere Mails in meinem Posteingang zwar noch von der Überschrift vorhanden waren aber wenn ich drauf klickte waren die Mail leer, ohne Inhalt. Ich habe dann den Rechtsklick gemacht und auf reparieren gedrückt - jetzt sind diese Mails ganz aus dem Posteingang verschwunden!

Ich hab nun im Internet ein bisschen gelesen, da wird davon gesprochen die msf (?) datei zu suchen und diese zu löschen. Und beim neuen öffnen von Thundermail würden dann die Mails alle geladen werden...Ehrlich, da traue ich mich nicht so wirklich dran, löschen hört sich immer so "böse" an...

Zur Verdeutlichung: ich habe den reinen Posteingangsordner und in diesem Posteingangsordner liegen viele Unterordner als seperate Ordner. Und eben diese separten Ordner die als Unterordner im Posteingangsordern sind dürfen NICHT gelöscht werden!

Also Hände davon lassen oder kann da nichts passieren?

Danke schonmal für Eure Hilfe.

We are undergoing an accessibility audit of all our information communication technology solutions for a local government entity. This audit is to ensure our compliance with the updated Americans with Disabilities Act Title II Rule on Web Content and Mobile App Accessibility regulations in advance of the April 2027 enforcement date.

Does an Accessibility Conformance Report or VPAT with the WCAG standards used and conformance level noted exist for Thunderbird? We are hoping to find these for Thunderbird Desktop as well as Thunderbird Mobile (iOS and Android).

Why is thunderbird constantly coming up with an authentification failure while trying to connect to outlook.office365.com every time i try to access my hotmail emails? this is becoming painful last week zero access to hotmail then worked for a few days now nothing again.

Hello all,

Apologies if this is going over old ground. I've tried the usual Repair Folder fix without success and I'm cautious about trying anything further without some expert input for fear of doing more damage.

Thunderbird version: 140.12.1esr (64-bit) Windows version: 11 Server type: POP, messages not left on server Inbox " Folder properties" reports: 16384 messages. 13.8GB on disk

The Entire contents of Inbox disappeared after the following sequence of actions: 1. Tagging a selection of messages (in Inbox). 2. Making only those tagged messages visible (using Quick Filter). 3. Selecting all of the visible messages (select first, shift-select last). 4. Deleting the selected messages (Del key) The intended messages were successfully moved to the Deleted folder.

The Inbox now appeared empty. At this point only tagged messages were set to be visible but these had been deleted so an empty Inbox pane seemed correct. Resetting the tags visibility of Quick Filter did not make the messages reappear.

The messages are however visible and openable when doing either a straight folder search or when using a search folder. Inbox Folder Properties reports that the messages are still present and the reported size on disk seems appropriate for the number of messages.

Messages in all of the other folders are visible.

At this point I did a complete Export of the profile. When I discovered that Windows would not recognise the resulting .zip file I also did a straight copy of the Inbox file within the profile folder to a safe location (I understand that the export .zip file is intended for re-import to Thunderbird and that Windows might not recognise it).

I then did a Repair Folder (within Folder Properties dialogue). This made no difference although the size of the Inbox.msf file reduced dramatically (I didn't make a note of the before and after sizes).

I then quit and restarted Thunderbird several times. This at first made no difference. After perhaps 3 or 4 restarts however a relatively small number of files have reappeared in Inbox (a tiny percentage of the correct total). Curiously, most of these (but not all) are marked as spam. Ordinarily I would delete all messages marked as spam but there are probably some that I have missed. It looks rather as if the files which are now visible in Inbox are ALL of the spam messages plus a handful of others. Of the 172 messages which are now visible they were initially correctly reported in the folder pane as being 172 unread messages.

Another strange thing is that when selecting the Inbox on the folder pane, the small number of messages which become visible only appear after a delay of perhaps 10 seconds (previously this was instantaneous). When selecting any other folder, the messages are displayed instantly.

I'm not quite sure what best to do next. I haven't yet tried deleting the Inbox.msf file. Any wisdom will be gratefully received.

Thanks in advance.
