Can I delete the data from the unused accounts ONLY, without a complete deletion of all data and account information?

C:\Users\***\AppData\Roaming\Thunderbird\Profiles\**********\ImapEmail

still has the data from 13 email accounts although only 4 accounts are still in use (see attached image). Data volume is at 22G. Approximately 15G is leftover from unused accounts.

Can I delete some of the data from the unused accounts, without a complete deletion of all data and account information?

I've installed TB on my new laptop and now, when I try to print an email, my list of printer options don't show up in the drop-down menu, only options to print to a PDF file. It says it's printing, but it's not. How do I restore my list of printers?

When I delete mail from the inbox to the trash folder the mail disappears, but the counter still shows the mail is in the folder. I suspect that I have a profile problem but I have no idea how to fix it.

RE: When viewing message in "Original HTML" mode, URL's not entered as links are not displayed as active links, but are displayed as active links when viewed in "plain text" mode. My question posted 4 years ago,

    https://support.mozilla.org/en-US/questions/1326405

had many replies and other indicating they had the same issue. Matt (https://support.mozilla.org/en-US/user/MattAuSupport) pointed to an outstanding request,

   https://bugzilla.mozilla.org/show_bug.cgi?id=920560

which had 12 years of conversation regarding the problem. Bug 920560 was closed 2/19/2025 by Wayne Mery (https://bugzilla.mozilla.org/user_profile?user_id=29811) without comment or any indication of a fix. I'm running a current version of TB and still have the problem. Is there a fix?

Hello: I send out newsletters to about 100 senior men golfers. I've been struggling with my messages going to spam or junk folders. My messages don't contain spam, but some mail servers are rejecting them. I've been working the problem (proper server authentication, DMARC, SPF, DKIM, etc.) but one of the suggestions I've read is to make sure there's an "list-unsubscribe" link in the email header. I've placed one in the body of the email at the bottom of the page (still fails), but how do I make a header in Thunderbird in which to place a link? Thanks for any help.

Although I certainly do not keep all emails, I do file a LOT. I have about 200 folders for topics and people. I use the filing feature EVERY SINGLE DAY. Suddenly when I looked at email today, the message filing feature is missing. I have to have this feature.

I am a retired librarian. This may explain my love of with organizing and storing. I suspect I am not the only person horrified to see things missing from Thunderbird today.

My husband and I have used Thunderbird ever since Qualcomm stopped supporting Eudora.

Messages going to JUNK is STILL a problem even today after the downgrade. I know to use Shift-J, but Thunderbird DOES NOT LEARN. This is annoying, but less important than the filing issue.

Explain this please.

Using Mac OSX, I can navigate via Finder: Library / Thunderbird / various Profile folders.

Or within Thunderbird via Help / Troubleshooting / about:profiles / profile data "show in finder"

https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-thunderbird-profiles#thunderbird:mac:tb128

The left is via Finder, the right via about:profiles. The xxx.default folder contains different contents in each Finder Window.

We have one email account set-up. Instead of receiving email in the Inbox associated with this account, the email is showing up in the Archive Inbox. Is there a way to change were new email shows up?

No issue with Sent email, just the Inbox.

Server is a POP

Thanks for any helpful thoughts.

how do i restrict Thunderbird from automatically switching to browser when a link is clicked yes, i want to open a browser tab for each link clicked, but i need it to be done in the background

Very recently (last 10 days or so), when downloading e-mails, Thunderbird is downloading the SAME e-mails to TWO different accounts! (This is new and somewhat concerning behaviour - I don't want one account receiving another accounts e-mails, for obvious reasons!) The accounts are "astratford@rogers.com" and "ajstratford@rogers.com".

I get DUPLICATED e-mails in EACH of these two accounts; I then go to the 2nd account, select ALL, then DELETE. Not disastrous, but time-consuming, annoying and a confidentiality issue - and a potential security issue.

I would like to know what might have changed to cause this behaviour.

As always, any suggestions or reply much appreciated.

I am reviewing all the things I'll need to do when using Migration Assistant to copy my 2011 MBP running High Sierra, which is a 32 bit Intel computer, to a 2023 M2 MBP which is a 64 bit machine.

I presume that Thunderbird 60.9.1 will not even open on the 64bit machine. It might not even copy over, does anybody know?

But I presume that the Library / Thunderbird / Profile data WILL copy, so I can install the newest version and then (restore or replace ???) the default Profile using the instructions ?

OR will installing a newer version wipe out the old Profile data on the new computer? Or will it create another set of Profile data (with a different random number prefix) ? Should I put the original Profile data on a thumb drive so I can simply delete the "new" profile and copy the original Profile files to the correct location?

https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer

I suppose I should copy the current Profile to a storage medium like a USB drive before Migrating, just in case?

I am confused by this: "Test Thunderbird on the receiving computer - it should look identical to your original on the sending computer and contain all the same messages. CAUTION: Do not open Thunderbird again on the original computer - unless you repeat the process in reverse to transfer the folder contents back to the original computer before opening the app. (If you forget, you can manually check one version against the other to ensure important messages are retained, but it's messy and time consuming.) "

Is this referring to not having two instances of Thunderbird running at the same time, trying to share a profile? Certainly I can continue to use Thunderbird on my old computer ???

Or does the COPY/PASTE method described in these instructions actually delete the files from the old computer? ... which I would call MOVE instead of copy ?

I have my account setup as POP (or is it PPP...) , so my emails get saved on my computer. And I have the server save downloaded emails, so I can download everything to two different computers. Just not at the same instant.

More confusion -- Within the Thunderbird HELP dropdown, "profiles" I see: "View an installed configuration profile - Choose Apple menu > System Preferences, then click Profiles. - If you haven’t installed any configuration profiles, Profiles preferences isn’t available. - Select a profile in the Profiles list to view information about it."

When I goto Mac Preferences, I do not see a Profile Manager, and the instructions indicate that it won't be there unless I have created a profile. I'm confused by this, can someone elaborate? What does it do besides take me to Library / Thunderbird / Profile  ? Should I create one to help in Migrating? How?

What is the distinction between the Profile created by Thunderbird, which does NOT trigger creating a Profile Manager tab in Mac System Preferences, and my creating another one (why would I do that?), which DOES trigger creation of a Profile Manager tab ???

MOST IMPORTANT: in the past, some "major updates" have forced me to do the SETTINGS process all over again, and I have a number email accounts so it was tedious. Maybe because I didn't know about how to move my existing Profile. Also a few years ago, verizon/AOL mail forced me to change to something new, "AUTH" or "OATH" (?) and that was not fun. Somewhere I have notes on how to do this (the actual data I need to input into all the Settings fields) but I don't relish having to locate it all. Its been MANY YEARS - which is great, except when you have to learn how to do it all over again.

I know how to move a Profile after Firefox updates via about:profile - but you have to make a note of WHICH profile is your active/default one, BEFORE updating Firefox. Otherwise you have to go thru all of them to find it - they are not dated ! The Profile name should include the date and the Revision number !

In the past, the message list columns would automagically widen proportionately when the window was widened. With that I could temporarily maximize the window to see more subject and sender details, then restore it and have the columns go back to their former width. At some point in the recent past that went away, and now the columns must be manually adjusted when stretching or shrinking the window width. I was hoping with all of the message list changes in 140 that this would be fixed. It is not. What can be done to restore this feature? I'm not sure why it was eliminated.

Additionally, I have found that in 140, when closing a message after opening it from the message list, the message list disturbingly scrolls all the way to the top and then back down. I suspect this is a bug brought on by the other message list adjustments/improvements.

I am trying to add my BT account. I had it on Thunderbird and it kept saying couldn't connect . I deleted it (much to my horror I have lost everything) and now I am trying to reinstate. I have changed my password and BT emails work perfectly fine on my android phone

TB 140.1.0esr The accts are pop/smtp not IMAP.

I was moving subfolders around using drag & drop instead of Moveto or Copyto. Several folders (along with contents including emails and sub-sub folders) were moved OK, but the last one I tried only moved the subfolder and its sub-sub folder, but not the email contents of these. Not sure what I did differently but It left the folders in the original location and created a copy of the folders in the new location, but both sets of folders are empty. Using the properties->repair on each of these folder sets did nothing.

There were only a few emails in the problem folders, and I have created an TB export file after the fact. Is there any way to directly inspect profile entries to see evidence of the missing emails or maybe other recovery steps?
