Hi Everybody All of my folders in Thunderbird have become subfolders, which is annoying, but worst than that, most of them don't have messages in them any more. What have I done, how can I undo it and find those messages? I hope someone can help. thanks Rose

Previously all of the email accounts created in thunderbird worked flawlessly, one day when checking email automatically a seperate window opened displaying the error "Access Denied", I searched the net for a solution and could not find one, it is very possible that one of the most recent linux updates may have changed something as I recall a larger than normal update just before this occurred a few days ago.

Thank you.

Access Denied You don't have permission to access "http://login.xfinity.com/login" on this server.

A couple of months ago Thunderbird started being very slow in multiple situations. I use POP3 and download all mails. I have fairly big mailboxes, some of them up to 2½ GB.

1) Downloading e-mails is slow.

But the worst is this one:

2) Clicking on unread mails first time. This can easily take 10 secs, where the app goes "not responding" and finally "Loading message...." With 10 new mails, it is a lot of wasted time.

3) Dragging mails from one mailbox to another Some of the same behaviour as above.

I have tried to compact mailboxes, but that doesn't help.

I am on release 128.4.1esr (32-bit), windows 10.

I am having a problem syncing my Thunderbird folders with iCloud. Every time I have to explicitly check that I want to subscribe to all IMAP folders in my iCloud account. Then after a short while a lot of folders get unsubscribed and I have to subscribe them again. I have experienced this instability with both Thunderbird and Betterbird as well as on Windows 10 and Pop_OS! 22.04. More people have reported the same issue, but no solutions have been shared:

• https://support.mozilla.org/en-US/questions/1441368
• https://support.mozilla.org/en-US/questions/1444029

Does anyone know how can I fix this?

When I start Thunderbird 128.5.2esr (32-bit) on my Windows 10 Home PC Version 10.0.19045 Build 19045, it has become increasingly slower recently. I have been using it for many years now and up until this year it would typically start in ~30 seconds.

I am accessing three separate POP email accounts and each of them has a number of subfolders with important stored messages. I thought that perhaps I had just too many folders and messages, so I removed hundreds of the stored messages and some of the sub folders. I routinely compact all accounts.

Today, it took over 8 minutes for Thunderbird to open. Incidentally, once it opens initially it seems to perform normally thereafter.

Is there something that I can do to speed things up?

Thanks in advance, Rich Green

When I get an email with attached jpeg-file it is not possible to open that file. Before a message box showed up and let me choose program to open with but this is not the case any more

To open an attached pdf-file works fine

Thunderbird suddenly can't connect with my email servers. A box from Xfinity pops up: • Xfinity: Sign in with your Xfinity ID (for ***@comcast.net) • but when I do: Access Denied You don't have permission to access http://login.xfinity.com/login on this server. Reference #18bffcc317.1734841179.1c89c1f5 https://errors.edgesuite.net/18bffcc317.1734841179.1c89c1f5

Also Thunderbird error messages: • Authentication failure while connecting to your server imap.comcast.net And Thunderbird error message: • ~Connection to yahoo timed out And my Inbox messages don't show

Please help. I see no cause for this, didn't download anything today. Thanks, Lynn

When I use my PC (main device) Thunderbird shows individual mail folders, on my iPad the default mail client as well as individual account folders has an 'All Inboxes' This is very useful as 95% of my mail will go to one account .... so having an 'All folders' account ensures I don't miss a mail arriving on a less used account.

Is there a way to set this up on Thunderbird?

I’m using Thunderbird on a MacBook Air M1 2020 with 103 GB of free disk space and 8 GB memory. I’m using it primarily as a calendar and task management system because I like the reminder options in Thunderbird. I use local calendars. Thunderbird auto-updated to V 128.5.2 from V115.18.0 on 12/17/24 (I didn’t realize auto-update was set) and since then gets hung every time a reminder comes up and I either dismiss it or snooze it. I have to Force Quit Thunderbird to get the spinning beach ball to go away. I backup my computer weekly using Time Machine and tried restoring to 115.8.0, but was unable to restore my profile with my current calendar items on it. I got an error message saying that the new version of my profile (with my local calendars) is incompatible with Thunderbird V 115.8.0. Is there any way to get my current calendar info into an older version of Thunderbird, or better yet, create a fix so that it doesn’t get hung? If it's time for me to move to a different application for this use, just be honest. Thanks in advance for your advice and expertise!

I live in Peoria, Il USA. our service provider is Comcast. I use Linux Mint Cinnamon 21.3 ver 6.0.4. Just about a month ago, I found I was not able to send emails. I can receive emails easy, but not send on either of the 2 email accounts on my desktop computer. When I tried to send a message I received an error telling me I didn't have permission, so I took pictures of the error messages to the local Comcast office. They told me I needed to change my password.

    After changing my passwords, I tried to send an email to my alternate account and received a "sending message" notice.  I left it in sending message for over an hour.  I closed the sending message.  Then checked all of the account settings and preferences, and changed one setting to "normal password", and repeated the test, I receive the same results.  Using "Software Manager" I uninstalled "ThunderBird" then re-installed "ThunderBird" via  the gui.  I tried the same test, and again received the same results.

    I again went back to the Comcast office and reported my results, I was told that there were 2 other complaints about the same situation, I asked what their solution was and was told to just log into my Comcast Account online to send emails.  I asked them what did Comcast do that caused this problem, I was informed that they are just a sales office, I asked for a phone number for tech support and was told that they don't have a phone number to tech support.

    So, it seems I am on my own to fins a solution to the situation they caused, can you help?

    If there is any further information you need feel free to ask.

Thank you, Evan James

I have Mozilla Thunderbird Version 128.5.2esr on a desktop with Windows 10 Pro. This version of Thunderbird has the message pane to the right of the email list. I very much prefer the older style where the message pane is on the bottom (the full width of the window). Please let me know how to change the settings so that my message pane will be at the bottom.

Thunderbird won't remember where it was last time (windows 10 and 11). Every time I open it, it has shifted and resized a bit from the last time. It's not one monitor to another or even the other side of one screen, but it's always slightly higher or lower, slightly smaller or larger... It's just driving me nuts because everything else is perfectly positioned. Note that I am using fancy zones to do this placement, but everything else works fine.

Hello, I have a Thunderbird problem: If I "print" a photo into a PDF, the PDF file is perfect. If I now send this file via Thunderbird, the recipient of the email, as well as I as the sender, receive the attachment in strips, in poor quality, unacceptable quality. The attachment is not particularly large and is under 5 MB. I use 2 email sender addresses from different providers that have no size limit. The recipient does not have this either. What is the problem? Kind regards, Charly
