Thunderbird Community Forum

Thank you to David & Toad-Hall who kindly worked to get my Thunderbird to download my messages from Juno in a series of support messages in mid-July.

I have worked with KW, a computer help person at my senior center. I have a follow up appointment with KW on Fri 8/16, 1 pm MDT. Last session KW succeeded in re-setting the STMP server port to 25 and the POP3 server to 110. See screen shots.

This did NOT enable Tbird to download my messages from JUNO. There was a' change, Tbird would no longer SEND messages via my Juno account, earlier it would send test messages. see 3rd screen shot

Like Toad-Hall, KW is suspicious that the last message Tbird downloaded from Juno 6/26 that directed me to reset my password in Juno was malicious. We reset my password and Juno & Tbird both open with the new password I set up directly from the Juno webpage.

KW suggests I ask you if it is possible to deinstall & reinstall Tbird, Might that restore Tbird to function? Would I lose the contents of my saved messages in folders?

Additional screen shots, maybe useful info.

I really love my Thunderbird! I like to work off-line, I like storing my files on my computer computer.

For the second time in the past month, I'm getting a mysterious message every time I open Thunderbird. I'm getting the following message:

"Warning: Potential Security Risk Ahead

Thunderbird detected a potential security threat and did not continue to live.thunderbird.net. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details."

In addition, I'm unable to send or receive anything to my gmail addresses. On the other hand, my earthlink addresses are working fine.

The last time this happened, eighteen days ago, the problem mysteriously disappeared ten minutes later. No such luck this time; it's now been about twenty minutes and no sign that the problem is going away.

Help, help, help!!!

Is there a way to show only the inbox's unread count in the sidebar when the account is collapsed?

Currently any unread messages are being counted, but personally I would like a way to only show the count number if those messages are in the inbox.

One example of this is sometimes I do not need to read a message and immediately archive it without reading and do not need to include that in the count, but its still nice to leave it unread in the All Mail folder just for future reference.

Been a Tbird user (and donor) for years. Last few months sending Gmail is slow, frequently:

Often 30-60 seconds with just text in email Can be >60 seconds when forwarding an email with embedded links or when sending an attachment.

My setup below. No other app or network issues on my 2 year old Dell Windows 11 PC or with other devices in my home Eero mesh network. No non-Tbird Gmail problems from my phone or iPad.

Any simple solutions here? Thanks.

My Thunderbird Specs

Version 128.1.0 (problem has existed well before this release over last few months) with all installation server setting defaults: pop.gmail.com Port 995 smtp.gmail.com Port 465 Secure Connect SSL/TLS Authentication method OAuth2

My wife's computer crashed and I've brought it back to life, but her Thunderbird profile is now gone. We have an IMAP server with all of her emails stored there, going back years. When I configure her email back to that server, is it going to automatically begin downloading all of her old 'read' email, as well as whatever 'unread' she's missed over the past few days? Or, is the IMAP server going to look at her new Thunderbird folder and seeing that there is no email there, attempt to match that on the server end by deleting everything 'read' at the server and only downloading what is 'unread' into her Thunderbird?

I can access her email by Webmail and it's all still there, but I want to make sure I'm not going to create a problem once I reconfigure it on Thunderbird on her computer. I'm guessing I could mark everything as unread in Webmail and then it will all be viewed as needed to be downloaded locally.

Any suggestions you might have are greatly appreciated.

After getting help from you to delete all Thunderbird data on my old laptop (Many thanks David!) I successfully installed a new copy of the software. I copied all the information that my desktop p.c. uses to collect my emails but the new Thunderbird on my laptop will not accept the server and logon information. "Thunderbird failed to find the settings for your email account" They work without any problems with Thunderbird on my PC. There does not seem to be an option to manually set up the server information. I have tried both POP3 and IMAP but neither work. Any help welcome.

Have used Thunderbird with Comcast/Xfinity for over 10 years. I can receive all of my email on Thunderbird. About 6 months ago I started to not be able to send emails from Thunderbird sporadically, but it has escalated to the point of not being able to send emails of my comcast.net accounts at all. From my gmail accounts I can send messages just fine through Thunderbird. Three weeks ago I spent 2 hours on the phone with Xfinity. Reset all the passwords, checked all the settings, etc etc. For the rest of that day I could send all emails through Thunderbird. Ever since that day, same problem. I spent another 2 hours on the phone yesterday with Xfinity and they are sending my issue to a 3rd or 4th tier support person. They say there is no guarantee they will find a solution and that I won't hear back until Monday or Tuesday. Also this is the same problem on 2 different computers. One computer has the newest Thunderbird update to version 128.1.0esr and the other has the last version of Thunderbird as 115.14.0.

Here is the exact error message I get when I try to send an email:

Sending of message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: resomta-s2p-647654.sys.comcast.net resomta-s2p-647654.sys.comcast.net Excessive failed authentication, ESMTP server temporarily not available.

The numbers after s2p- change for each attempt to send an email.

Believe me I have tried all sorts of different settings and I have read practically all of the solutions I could find on Mozilla's support forums and articles.

Really need help on this one. Jennifer

I've tried importing my old profile into the new profile. I get the following message: Import failed unexpectedly, more information may be available in the Error Console. Can I copy and paste folders like my old LOCAL and CALENDAR folders into my new profile?

I'm under the impression that the following setup used to work well, but ceased to sometime in the past:

Filter 1: ("junk from unknown senders"), enabled. - Apply filter when: Manually run, Getting new mail -> Filter before Junk Classification. - Match all of the following: From - isn't in my address book - Personal Address Book. - Perform these actions: Set Junk Status to: Junk.

Filter 2: ("delete all junk"), enabled. - Apply filter when: Manually run, Getting new mail -> Filter after Junk Classification. - Match all of the following: Junk status - is - Junk. - Perform these actions: Move Message to - Junk on myaddress@myprovider.com.

Filter 2 is lower down the list of filters.

Filter 2 works as I expect it when I run it manually with 'Tools'->'Run Filters on Folder'. However it is either never executed, or never succeeds in moving messages to the Junk folder when it is called automatically under the "Getting new mail" condition. I check mail automatically every 10 minutes on this IMAP account, but the messages marked as Junk by filter 1 are never moved to the Junk folder.

What might explain this?

Thanks and appreciation to all the volunteers answering questions for the public on this site.

Details: running v115.13.0 on Debian.

With the recent update to Mozilla (128.1.Oesr), I'm no longer able to check my email at my work address. I get an invalid certificate error. I have always gotten this error at this address but in the past I've been able to ignore it and keep on. Now I don't see any option to ignore it, and I'm unable to check my email. This is a non-starter. I need to be able to keep in touch with work.

Thanks, John Mumaw

I recently upgraded to Thunderbird 128 and in my email archive from 1996 to 2008 I am no longer able to view any emails from prior to June 1999. I just get a blank page when I open the messages. I can still see the email summary under the folder.

Is this a known issue with the release?

How I can better diagnose what it going on? The emails were previously ok on prior versions.

Thanks.

Michael.

Hi First, I'm using the Swedish version so I can't give the exact names on the checkboxes etc.

I want to turn of Junk filtering So I checked in the help sections and there is a checkbox for activating the junk control in the options for my account, it is already unchecked. But Thunderbord moves emails to the Junk folder anyway?

So how do I stop it?

Hello. I get a pop-up every few minutes from Motilla Thunderbird informing me that I should update my access to my (secondary) Gmail address. I have done all which is recommended on the information sheets entitled "Automatic Conversion of Google mail accounts to OAUTH 2.0 "authentification" but, unfortunately, the pop-up keeps coming. Moreover, after the update, I've lost all my mail received on my main email address. I include a screenprint of the pop-up. Thanks for your assistance.

Strangely, I can't figure out how to add to someone else's post if it doesn't already have replies so I'm having to start my own thread. Anyway...

Thunderbird on my system is 32-bit on 32-bit Windows and a day or two ago it updated itself to version 115.10.1. Since then it's been slow at sending emails, receiving emails, applying filters and pretty much everything else. Is this being worked on? I saw a couple of similar reports from other people here but like I said, I can't add a reply to them.

And if it's not known about or being worked on, is there some way I can roll back an update?

Deleting msf files does not solve the problem. Turning off windows firewall (a bad idea) does not solve the problem. I don't want to swich to a new mail program after years of using Thunderbird. Can anyone help?

I usually work with my computer hardwired to my router. For some reason, this is not working anymore and now I have my computer connected via wifi. As soon as I changed from cable to wifi, Thunderbird started to ask permission to connect to my Google account every time I open Thunderbird. Sometimes I have to grant permission several times. At some point, it stops and I can keep on with my work until the next time I restart my computer and open Thunderbird. Then the cycles starts all over again. Any ideas¿?

In Thunderbird, I lose e-mails when I try to transfer them from my "in" box to my "save" box. I've deleted a lot of e-mails, hoping that would help. But it didn't. Can anyone help me figure out what's happening?

Receiving a 'bounced' notice in my inbox that tells me to advise sender to reduce the size of their message. It does not tell me who the sender is. How can I figure this out?
