Thunderbird Support Forum

My Thunderbird has been working properly for about 30 years, but now refuses to open. Message received says 'Authentication failed'. This happens repeatedly (for at least 20-30 times) and appears to relate to my password. It suggests 'Retry' or 'Enter new password'. The 'Retry' repeats as before so I check the Saved Passwords and enter the one saved. I get the same message. I am using Version 115 and have been for some time.

Could this be related to a change of Profile? There must be a way to reset the password? I have checked all the settings and no errors appear, all settings confirmed.

I have thought about a Recovery Mode and seem to remember seeing a message that I do have that. I just don't know how to access it.

I currently receive all messages sent to me including those from Comcast but I can't send messages to any email address. When I logon i get the message: Enter Credentials for my email address on imap,comcast.net. I read the document: Switch from POP to IMAP account > Create the IMAP account. I never saw the window shown on page 3 of the document. The other day I got a message that the IMAP account was already created. I then edited the my SMTP account.

Certain email newsletters that I signed up for (and verified) go directly to trash. I have no Thunderbird filters on nor does my internet or computer. How can I fix this? I switched from Outlook but sadly, will have to go back if this isn't fixed.

Hello, It's there any option/setting in mozilla thunderbird for drag and drop emails to local drive folder and save them under another filename that the standard "Subject" name? I don't know if i'm clearly enough, that's why i want to make a briefly description of the operation i want and the way the emails i want to appear in my folder. I drag and drop an email to my folder and this email has the filename represented by the "Subject" of that email. Can i change the way emails are saved ? Or can i drag and drop emails from one sender in separate folder ?

Hi, I have very frequent Mozilla Thunderbird Crashes on the site. I have noticed that it appears mostly/all the time? when some emails are being deleted, if that makes any sense. This is more of an annoyance, than a critical issue. Just in 2024 the log shows over 100 submitted crash reports. The "good news" is that Thunderbird goes to the "restart and/or quit" option icon for a a fast restart. So any thoughts, suggestions would be appreciated. Thank you . Gerry K.

Why has Thunderbird started to continuosly ask for the passwords for my email accounts? And why do all my attempts to enter my passwords result in failure? I am unable to send or receive any emails at the moment. If anyone is able to help I'd be very grateful.

I am running Thunderbird version 115.4.1 on the Windows 11 system. Having Thunderbird active (even in the background or minimised) stops the Windows key from working. How can I get the Windows key to work normally without closing down and exiting Thunderbird?

I have already several times asked my question and have received no reply so far. Could you please reply to my e-mail: jean-pierre.biber@natcons.ch Here my question again: Good evening I have been using Thunderbird mail for ages, and now suddenly diverse thing don't work anymore: I can't chose my signatures anymore, the language correction does not work anylonger, and when I print things they come out wrong. Can you please help me fix that? My email is jean-pierre.biber@natcons.ch Kind regards Jean-Pierre Biber

Our Thunderbird is set up with 2 email accounts - Gmail & Cox cable. Actually 3 as my wife also uses TB for her Cox emails. Cox is moving over to Yahoo. Not a fan of Yahoo. Eventually I will either set up another Gmail account (cox was for subscriptions or when a business needs an email address) and my has a Gmail already, but she does not use TB for that as for her Cox is her main email.

So can I delete our Cox emails thru Cox web email site without losing our emails currently in TB? And will that mess things up as TB sends and receives email from cox cable?

Any tips and suggestions much appreciated.

There is now a new line of all my emails just below the T/bird menu. I hate it! How can I revert to seeing all emails separately in the main email body and losing that line?

If they are not signed, it will send smoothly even if they are encrypted.

For past 24 hours only, I have been unable to open email attachments. v115.7.0, however last update was 31/01 and has worked perfectly until now. Still use Windows 10.

Double clicking on attachments does nothing, other than popup software option for formats without specified defaults. Either way, no indication that attachment is opening.

"Save as" is saving attachment document to target folder, however trying to open these errors, suggesting document is corrupted or in incorrect format.

Have tried restarting system to no effect; likewise error continuing in troubleshoot mode. Cannot see any obvious settings that would impact this, nor have I consciously altered any of these.

I'm certain this may be an easy fix, or my own error, but this is eluding me.
