I installed Thunderbird on a new Windows 11 desktop. I thought that I did the all the correct things for transferring my local folders. On the portable hard drive I can see the *.msf files. But when I copy them to the new computer they don't show up when Thunderbird launches. I copied them the same folder as on my old desktop. I even tried different folders on the destination desktop to no avail.

So I'll just ask, where should the *.msf files reside?

TIA.

After the last Firefox update, my bookmarks list only highlights the thumbnail image. The descriptive text which was previously in white colored text is no longer colored but faded and not readable. How do I resolve this problem? Zak

I have a couple of hundred filters and one of them occasionally kicks in and unexpectedly moves certain messages to a new folder but I can't figure out which filter it is. Rather than me going through every filter manually, can't Thunderbird tell me which filter affected a given message? I'd like to be able to right-click a message and be shown the exact filter(s) which affected it.

Hi All,

I have a number of computers that I would like to have configured identically, including Firefox's extensions. Is there a mechanism that I could use to automatically install a list of extensions on my (linux, windows) computers?

TIA, Mike.

I was running TB 128.11.1esr up until 10:00 this morning on Windows 10 Professional 22H2 64-bit. I have some e-mail messages that I cannot delete. This morning I auto-upgraded to 1o 128.12.0esr and then to 140.0esr. I still cannot delete the messages When I try to delete a group of messages (containing the message in question), the messages in the in-box turn from black to gray, and I see at the bottom "Moving messages to Trash". But nothing happens. I did a "Compact folders", and it completed without any error messages. I can look at my Trash folder, and the contents seem to be intact. In one case, I individually deleted all of the messages except one. With this one, I open the message and see nothing in the bottom message content pane. When I do a "cntl-u" to see the RFC 5322 message headers, I see a window that is completely blank. What is happening, and how can I debug this? Thanks.

While looking for another setting, I noticed that a setting about how T-Bird handles spam mail. I have it checked. Today, I received a DOOZY of a spam mail, but Thunderbird didn't flag it. It was so obvious spam, as it asked for credit card, banking, automobile license! Also, the Subject asked to update payment info, but the From field wasn't that company.

Hi! I recently lost my old laptop and I'm trying to setup my new laptop without a backup. I was logged into my mozilla account on my old browser before I lost it, but I'm not seeing any of my old tabs, bookmarks, and extensions from my old browser syncing to my new browser. Is there anything I can do to retrieve this data without having access to my old laptop? Thank to anyone who can help!

Thunderbird ver 140.0 (64-bit) on Windows 11.

Brand new, fresh installation of Thunderbird. - Added a GMail account. That worked. - I tried to add an account with my personal domain. I enter my name, the email account, and Thunderbird gets stuck in an unending loop looking up the configuration. - Other email clients have successfully looked up the config and did the setup without a problem. - The email account is handled via IONOS.com servers. - If you gave me a manual setup option I could handle it but there is none; TB goes straight into trying to handle it itself.

Any ideas?

TY, Frank

i made a donation last week to thunderbird , but the inbox folder is blocked asking for a donation and not letting me open the emails attached i show the page that appears on the inbox

Hello! I am an avid user of firefox (especially with adblockers) on a windows 11 PC. Unfortunately, I have recently been experiencing an issue where when I attempt to open firefox, a window will open for a split second before instantly closing again. My PC is up to date, I have tried refreshing firefox and doing a clean install, but cannot seem to overcome the issue, or even open it in safe mode. Does anyone have any advice? Many thanks in advance!

Hi all, I have a new Computer and I'd like to transfer my Thunderbird installation with the complete settings (folders, mails, archives, address-book, ...). Also the calender would be of interest, because I have some settings which I want to keep. Is there any way to do this? I have access to my old computer, so I could export everything there and import that on the new one, but I did not find something to do that. Can you help me? Regards, Gerhard

Sometime in the past year or two, ONE of my four accounts started starring (putting the yellow star) on ALL emails I sent from that account.

This is not happening in the other accounts, including an account from the same university email system. If I send an email from the affected account (cischair) it is starred when viewed in cischair but not in the other account I sent it to (suthers). If I send an email from the other account, suthers, to cischair, it is not started in either account but my reply from cischair to suthers will be starred, again only when viewed in cischair, not in suthers.

It's very annoying to have to uncheck the stars on everything I send, and makes them useless.

Of course, I have looked in Account Settings for something that turns this on and off, and have not found anything.

Could you tell me where this might be set, or perhaps inadvertently by some keystroke combination (the bane of usability)?

Thanks - Dan

What's up with this? Two fake Trust Wallet add-ins were disabled within the last couple of days after one stole my money and I reported it, and another similar one. They had been pinned to my toolbar and they were subsequently taken off from there with the message that they had violated Mozilla's policies. Now I see that again there are two of them. How can this be prevented? The most obvious sign that these are fake is when one goes to create a new wallet the add-in directs the user to import instead, i.e. it wants to steal private information like recovery phrase.

So when I open some websites such as the RimWorld wiki ( https://rimworldwiki.com ), whenever i scroll my gpu for firefox launches straight to 100% and becomes extremely laggy. I have no idea what is causing this. My friends and other browsers run it completely fine. I have tried troubleshoot mode, gotten rid of all my extensions and themes, removed all cookies and cache and nothing works. My drivers are all updated, and I have truly just given up. If anyone has any solutions I would be much obliged.

I've been using tab grouping and it is really helpful.

But this morning when I created a new tab group called "MISC" I was unable to add any tabs to it.

1. I noticed that this new group happens to be the 11th group I've created. So I'm guessing that there may be a limit of ten groups. Am I right?

2. And now, some hours later, I see that the new MISC group does appear on my tab bar, but one of my old groups, TECH, has disappeared, but its contents seem to have been added to the MISC group.

Copied Thunderbird Profile on old computer to external HDD. Name assigned was zs6…. Installed TBird on new Win10 PC, omitting sign-in procedure. On this PC, clicked Menu, Help, Troubleshooting Info. Opened Profile folder on this PC, left-clicked Roaming, closed TBird. Copied zs6… from ext HDD, pasted onto TBird folder C:\users\owner\appdata\roaming on new PC. Clicked Yes to replace any existing files. Opened \roaming\thunderbird\profiles zs6…. not in there. TBird launches again in Setup. What am I doing wrong?
