I am having an issue with retrieving my email in Thunderbird. On laptop, using Version 140.2.0esr | Released August 19, 2025. No changes were made to Thunderbird settings. The email is showing up in the Comcast portal, but for now having it forwared to a Gmail account. Tried changing password in Comcast (and in Thuderbird) to no effect. Tried deleting my Comcast email account in Thunderbird and re-adding it, but no change. Can send out email fine, just receiving it is the issue.

Interestingly, I use BlueMail on my phone and it, too, has the same issue and will not retrieve from Comcast. Thanks in advance!

It makes sense that you might want your signature text to change depending on who you are communicating with (employer, business, friend, etc).

In Outlook you can enter several signature texts, identified by a name. I sure would like to have that in Thunderbird!

Another possibility would be to circulate among several signature texts, just to "keep it fresh".

Thanks for your consideration.

Need help setting up my domain name with godaddy and Thunderbird email client. need to get DNS Records from godaddy also. Having more trouble with this than I should, I think. I have already setup an email account on Thunderbird with earthlink/mindspring and icloud. No problems at all, in fact, both were very simple. But no so much with the domain name and godaddy. Any assistance will be greatly appreciated.

This started yesterday. Opening Thunderbird I get a popup saying its from Yahoo and it has my Yahoo mail address on it. If I delete that popup by clicking the upper right "X" another popup takes its place. And so, and so on. One popup after another all for various Yahoo products. Meanwhile Thunderbird can not be used - can't write, can't send and can't receive anything on Thunderbird.

What do I do??? If I reinstall Thunderbird I will loose all my saved emails, and anyway will that work???

I have run my antivirus, checking my whole disks, and nothing.

How do I get rid of the Yahoo popups???? Please someone help me.

I'm trying to set up a new email account in Thunderbird. I entered folders and selected email. I entered my name and email address, but the display started spinning and only stopped if I did a restart.

Help, please.

Please tell me what the difference is between "size on disk" and "user quota"? I don't understand why my mailbox is full when all folders take only 1/5 of the available space. My hosting give me 5GB, a user quota in mailbox is 4.7GB (in the app for computer: the main folder containing all other folders - properties folder - Quota - Storage: 4.7GB), size on disk is 853MB (in the app for computer: the main folder containing all other folders - properties folder - General Information - Size on disk: 853MB), and the weight of all folders is ~1040MB (the sum of the weights of all individual folders in the main folder). None of the numbers match. I understand that the sum of the weights of all folders is probably supposed to be 853MB, that the discrepancy is due to rounding the numbers. I understand that some space may be "lost" from the hosting because installation files take up some space, so I actually have 4.7GB to use, not 5GB. However, I don't understand why my mailbox is full, when from 4.7 GB only 853 MB is used?

Hello; Windows 10 & current version of Thunderbird. I am trying to add Messages Filters to filter out spam (getting more and more of that!) but the "OK" button on the add message filter is below the bottom of the screen. The window cannot be raised or resized to make the button visible. Photo below. Moving window does not allow me to raise window above top of screen. Keyboard (Alt-Enter) / Move will not work. Changed windows screen size just makes window larger but button still below bottom of screen.

Non-functional work around. Highlight Message name. Press Shift-Tab TWICE. Press ENTER. UGLY!

Thank you for your time and attention.

My old desktop PC video & audio died, so I installed the C drive into a new desktop PC as the 'F' drive. How can I copy my previous TBird email & addresses from the F drive to the new TBird location on the C drive? btw - I'm surprised that the fix for this common occurence isn't already in the on-line troubleshooting info.

Any way to minimize Thunderbird to the system tray?

I'm running TB 60.3.2 32 bit on windows 10 btw.

This bug report is irrelevant, as there is no such option in Thunderbird.

Also, all of the addon's that do it aren't compatible with Thunderbird 60.3.2 32 bit.

I assume that the post this could be a dupe of being 4 years old means I can post it myself.

Hi: I had the newest Update of Thunderbird Ver 52.7.0 installed in my PC running Windows 7 - Home Premium and was shocked that during this Update installation my foreign language Dictionary (Czech) installed in Thunderbird before this automatic-updating has disappeared. This is a very serious Software flaw because I was using this Dictionary for many years, and during several years I've added many unique foreign language words & terms and it is therefore very important for my correspondence with people abroad. My critical questions are:

1) does Thunderbird keeps a back up-copy of such an important part of this Software somewhere in the Thunderbird installation Directory so that I could recover/re-install it? 2) What are the specific step-by-step guidelines to install any additional Dictionary into Thunderbird? I've spent MANY HOURS trying to install a new copy of the Czech Language Add-On following the suggested procedure but it does NOT work - have anyone from the Programmers checked if this installation procedure actually works? An earlier advice would be greatly appreciated. Thanks.

After the last update, Thunderbird no longer requires a password be entered to sign into my emails. Hence all my emails are available to whoever opens Thunderbird. How do I get the Profile Password feature back again? This has nothing to do with the Master Password.

Hello, I followed the instructions to "Switch from POP to IMAP account" but I have a some concerns about the result. After activation of the new account, only "Inbox" and "Trash" folders were created on the client. Then I followed the instructions to Subscribe all the missing folders and first time I subscribed all of them. Then I noticed that there were two "Trash" folders, but only one of them was synchronized with the server. So I unsubscribed the Trash folder that was not synchronized. Is it correct? What is this second Trash Folder? Looking at the folder structure that has just been created for the new IMAP account on the client , I noticed that all the special folders (Sent, Draft, Spam, Trash) are contained in the Inbox folder, whilst for the old POP3 account (and two additional POP3 accounts) they were at the same level of Inbox. Is this the normal expected behavior for an IMAP account? I attached a picture with the folder structures. Thank you in advance.

When I try to install the Thunderbird Dutch language pack as an Add-On , then I got the message that the language pack is corrupt. It's not possible to download this add-on.
