Thunderbird Community Forum

We are facing issues with Thunderbird mail application.

Incoming emails are not being received in Thunderbird. Thunderbird is running very slowly and frequently becomes unresponsive. Sending and receiving emails is taking a long time. We have already restarted the application and system, but the issue still persists.

Kindly check the mail server settings and Thunderbird configuration from your end and advise on the necessary action to resolve this issue as soon as possible.

Your prompt support will be highly appreciated.

My Thunderbird was working fine today, all messages received, could send/receive email and all parts of my profile that I had set up (ie custom archive folders) were present and had emails.. I did a Windows update and when I reopened Thunderbird there was a pop up prompting me to login to my yahoo email. I did so and now everything is gone, all folders are empty - no emails and none of the unique folders I had created. The only thing that I can tell is still present is my address book. I am also unable to send or receive emails. When I try to send an email (to myself or anyone else) I get a pop-up "The mail server responded: Request failed; Mailbox unavailable. Please verify that your email address is correct in your account settings." I checked and the email listed is correct, the one I have been using my entire life. I also checked my Server Settings and they appear to be correct. (I have a cox.net email address which I transitioned to yahoo several years ago as instructed by Cox, as Cox no longer supports email - everything has been working perfectly until today) I also see there was a Thunderbird update done at 5:53PM today which would have been the same time I did the windows update (Thunderbird 153.0.3esr). I sent an email to myself from my yahoo website email and it never arrived in my Thunderbird Inbox but it DOES show in my Thunderbird "Sent" folder. I do have a Thunderbird backup ZIP file but unfortunately it is about a year old so obviously won't have some stuff I would not like to lose. Thoughts?????

I want to send an email to an address book list. I've searched for how to do it, and a "Write" button is needed but I do not have one. I tried right c,licking on the upper bar and chose customise. I see various buttons to add including "Write", but nothing I do adds it.

When I up dated the latest version of T.B.. when switching form the index desk top page to read the email, the page is blank EXCEPT for "SWITCH TO: EXTENSION" displayed at the top of the page

The T.B. icon is not is not displayed

The certificate for pop.3marysvilleprint.com is not vailid for that server. Someone could be trying to impersonate the server and you should not continue

When I open something in an email in Thunderbird I also get an extra new tab along with the tab for what I am wanting. If I don't delete this new tab, when I try to return to my email page it takes me to my Windows 11 home page. It only happens when I use Thunderbird and is very annoying. What do I need to do to resolve this issue.

when attempting to view my passwords, (by selecting in Thunderbird, edit, settings, passwords-saved passwords, show passwords), I can not see them because the window, 'Saved Logins' can not be resized. Scrolling left or right does not work and clicking and dragging the corners or edges does not work. All I can see is about the first 8 characters which is not the entire password. Also I used to be able to change the passwords in this window but that seems no longer supported.

Hello,

My email provider is Thunderbird for my professional email address and I use Gmail everyday for receiving and sending my professional messages. However, Gmail will no longer support checking emails from third-party accounts through POP from my PC.

The option to 'Check emails from other accounts' will no longer be available in Gmail on computer. The solution that Google proposes is to set up automatic forwarding (web): To get new emails to appear automatically in my main Gmail inbox (like with POP fetching), set up automatic forwarding with your other email provider (Thunderbird). 

Can you help me with the different steps  in both Thunderbird and Gmail settings to make it work? Alternatively, is there another way to still have access to my professional emails through Gmail? Maybe through Gmail app for computer that uses IMAP instead?

For your information: My Thunderbird server settings shows:  Server type: POP Mail Server Server name: pop3.mycompany.com Username: xxx@mycompany.com (my professional email address) Port 995 Thunderbird has been updated and is currently running on version 153.0.3. My computer is running on Windows 10

Thanks so much!

I've just recently (over the past 10 days) been notified about 3-4 times a day by Windows Defender which flagged "something" as Trojan:HTML/ScrInject.AW!MTB in "file" %temp%/newmsg.

That's where my copy of Tbird puts temp files. Closing it stops this behavior. Uninstalling and reinstalling w/out deleting my profile caused the same behavior, but uninstalling and cleaning out my profile files seems to have stopped this behavior.

I only have one extension, Compact Headers, and that doesn't seem to be the problem. Has anyone else experienced anything like this?

Currently using TB 153.0, Win 11 on desktop PC.

In past versions there was a progress bar on right end of the status line, along bottom edge of the screen, that showed progress while TB was compacting folders. That bar hasn't been visible in last few updates.

When prompted today, I allowed TB to start compacting. I'd permanently deleted a really big bunch of old emails in last few days, so probably a lot of space that could be recovered. I kept waiting and waiting and waiting, but without the progress I had no idea if TB was busy or possibly frozen. So I just left it alone. When I came back and tried to manually start compacting, it immediately said "Done, 0K saved". So it had obviously done the compacting.

If it's an option, how do I enable that progress bar? If not currently available, please consider restoring it in future TB updates. I -for one- think it's a very useful feature.

THX!

thunderbird has stopped receiving e-mails from century link. Configurations worked for two years as pop3, now won't connect. Tried imap configuration, same issue. Changed password (CenturyLink has problems with some password characters), still will not connect. AI (co pilot) tells me it is an issue since CenturyLink made changes, but they blame the email app (tried with Samsung app, thunderbird, outlook, none will connect. Connection thru CenturyLink web page works fine.

Hello,

I followed the steps to use the vCard option as a Email Signature.

When creating a new email the vCard Signature is not appearing.

Please Advise,

I have had Thunderbird from the time I acquired my Mac computer. This week it started to do something new. After a restart I opened Thunderbird. A box came up that says across the top System Integration. The cursor balloons, and hasn't stopped for the time I powered the computer, as least fifteen minutes. You know how the program icons are in a dock across the bottom. With other browsers open, hitting the Thunderbird icon doesn't bring its window into the forefront. This needs either a reset, or possibly a backup first. Is there a quicker way to fix this? Thanks in advance. I am not using a VPN; but I also have Thunderbird on my Windows 11. You might have seen a more recent thread on that installation. I included a screenshot. It was easier here to do that than on the Windows 11. On the Mac, I just had to use Activity Monitor to close out of Thunderbird in order to get its version.

I tried the instructions at https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer, and watched the video. Copied and pasted exactly as instructed - nothing happened. Is it possible to transfer the data, including message filters and in-box folders, to the new PC? Old PC: version 115.18.0 esr (32-bit) - on Windows 7 New PC: version 153.0.3 (64-bit) - on Windows 11 Or is this data transfer impossible due to incompatibility of the different Thunderbird versions? Thanks. I also tried transferring the data from the old PC to a slightly newer laptop on Windows 10, utilising Thunderbird version 140.13.0 esr (32-bit). Nothing happened there either. Is it a lost cause? Do I just go ahead and create new message filters on the new PC and forget about trying to transfer the data and associated rules? Maybe that's the way to go for me. Thanks.
