I-Thunderbird Community Forum

I run Thunderbird on a PC, and, to free up space on Drive C:, I have moved the contents of the folder Thunderbird in Appdata to Drive D:. I then changed my Server Settings, in Thunderbird, from C: to D:, and note that any new mail is indeed now appearing there along with those already transferred. This move could save me a valuable 6 gig of space, and more in the future, however, I am unable to remove that original Thunderbird folder entirely, notably I am unable to remove the contents of the Profiles folder, as it is still linked to the application. Notably with cookies.sqlite, cookies.sqlite-shm, store.json, mozlz4, aborted-session-ping and many others, which I note some have continued to be updated. I have been unable to find any other settings in Thunderbird referring to Drive C:, other than those in Server Settings.

I could presume that if I installed another version of Thunderbird on Drive D: and maybe moved those existing contents of the Thunderbird folder on C: onto Drive D:, and made those numerous settings changes to the App it could work. But I ask is there an easier way to complete this move? How can I complete this transition of Thunderbird from Drive C: to Drive D:?

I'm in the process of cleaning up Thunderbird e-mail before moving to a new computer. I started with 11,593 e-mails in my Inbox and 7,799 e-mails in my Sent folder. I'm now down to 7,634 in my Inbox and 4,965 in my Sent folder. I've allocated 2 weeks for this process and found that it's taking me about 3 hours per day to meet my daily goals. I'm finding that I'm spending at LEAST half the time responding to "Empty-Trash/Compact-folders" requests. There are times I can delete 50 e-mails at a time without getting a request. Other times I will try to delete ten e-mails and get the request. With the old version of Thunderbird I could literally delete hundreds of e-mails at a time. Can you help? Russ Bukwa Yardley, PA ps. I have intentionally given you specific numbers. Based on my software- and test-engineering experience, I speculate you need to create a stress test to solve this nagging problem.

There used to be a menu in the message header (lower right of screen) that included viewing the message source. I accidentally deleted it and cannot find how to restore it. I have looked through the Config editor and main menus and cannot find an option.

I used to use these add-ons

Old Icon Phoenity Buttons Phoenity Icons

to make Thunderbird more attractive, but now I'm having constant problems. The interface has become schizophrenic, and every time I open it, the icons have a different style, so I've been forced to disable the add-ons.

The question is, are there any supported add-ons left? I can't find any on the website. :(

Hi! I'm trying to set Thunderbird as the operating system default under Win 11. I tried to follow Mozilla's instructions: 1. Open the Settings application by pressing and releasing the Windows Start button, then clicking the gear icon. 2. Click the Apps icon, then click Default Apps in the list. 3. Click the icon under the heading Email to show your choices. 4. Select Thunderbird. The trouble is that at n. 3 there is no choice. There is only 'OutlookAccounts' and this item cannot be deleted or replaced. Can you help? All the best, Robifiori

When exporting an address book, all addresses are exported, without being divided into mailing lists. How do I make the address book exported divided by mailing lists? The full address book list is exported, without mailing list categories.

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?

I'm trying to setup Thunderbird for my Google Workplace account. 1. In the default settings, I receive the error message 'Profile not found' when I try and add my Outlook .PST file 2. I can't see how to access Profile Manager so I've started Thunderbird from the command line, activating the Profile manager, i.e. Thunderbird -p. When I add a profile and try and access my Google gmail I receive an error that the configuration server could not be found. Note point 1 where the same account was setup correctly but in the default 'no profile'.

Hello,

Recently I opened Thunderbird and it automatically added the following folders to my account:

https://www.imagebam.com/view/MEX6LYC

All the generic yellow folders below the Deleted trash can icon suddenly appeared and they weren't there or weren't shown before. I right-mouse clicked on the account folder, went to Subscribe, unticked the folders that I don't want to subscribe to (all the yellow ones were there), restarted Thunderbird and they all still appeared and the boxes I unchecked, had just rechecked themselves.

I don't want them shown. Is there anyway to fix this?

Thanks

Am I the only one that finds it almost impossible to change fonts. I can change what I type to Large. But that's all. I can't change anything I Cntrl-V into a message. Or inherit text in the process of a reply.

Whenever I open a message from the inbox into its own window, the message text and images are tiny and unreadable until I zoom (Shift-Cmd-+) them larger. And when I reply to a message, the text is also starts out tiny, but gets larger when I Zoom it up with the original message. Similarly, the column-header icons of the inbox are tiny, while the text is OK.

All the rest of the interface is normal and readable, except for the tiny text and buttons in the interface-command/confirmation boxes.

I have experimented with the suggestions in these question-replies, but to no avail:

https://support.mozilla.org/en-US/questions/1474665

https://support.mozilla.org/en-US/questions/1480963

I can adjust the font size and density from the "hamburger menu", just fine. And the MacOS 15.3.n-on-Intel settings seem right.

What am I missing? What else is there to change?

Thanks in advance... Alexander, long-time T'bird user

Running Thunderbird 136.0 (current as of 14 March 2025) on Windows 11 machine. E-mail account is hosted on office365 and has a personal (i.e., myname@mydomain.com) SMTP error " Connection to server outlook.office365.com timed out" Parameters were set per recent article on thunderbird forum for office365.

Using Tbird 78.14.0 (64 bit) with Windows 10. I can no longer access the Page Setup screen properly. I suspect it's because I accidentally put a very big value in for the top margin. The print preview for even a short email says it's many pages, there's no text visible on any of those pages, the only part of the Page Setup screen visible is OK and Cancel at the bottom, and I can't get to the top of the screen. I've tried closing and re-opening Tbird to no avail. How can I get to the top of the Page Setup screen to fix the problem?

Oh, woe is me. I had both Thunderbird and Firefox open on my desktop, and thought I was typing into Firefox's address bar. But Thunderbird was actually 'live' (selected?) on the desktop, so that's where my keystrokes went. Not sure what I typed or where the cursor was, but suddenly I have two folders in the left Thunderbird pane that I can't figure out how to get rid of. They are both just above my Local Folders: Templates and Archives folders for one email account, and an Archives for another. All three folders are empty (Archives had "2025" subfolders, but I was able to delete those). Keyboard strokes generated these, but they don't delete. What can I do? Can I navigate with Windows Explorer to where these folders actually reside and delete them there? I sure don't want to mess anything up. Many thanks in advance!

I don't like threaded conversations view. I turned it off so my inbox doesn't show it any more, but search results do and I find it impossible to find what I need. Is it possible to turn off ALL of those threading features across the entire program? Thanks

Hey, I'll try to keep this brief. Microsoft is forcing me to buy a new PC so as to "upgrade" from Windows 10 to Windows 11. My Windows 10 PC has Thunderbird (128.9.1--it says it's up to date) and it works just fine. I've spent over two hours attempting to set up Thunderbird on my new Windows 11 PC and...no dice. I'm at the end of my tether; I can't afford to waste more time on this. So...

--Thunderbird 137.0.1 (fresh download this afternoon--unclear as to the discrepancy vs. Windows 10 ver.) --Email = ATT --The setup program says it knows who ATT is and has the configuration --When I press "Done" for the setup to get everything going, it spins forever, then says, unhelpfully, "Unable to login at server. Probably wrong configuration, username, or password." --Needless to say, I've checked everything 48 ways from Sunday; let's assume that my email is correct --So if it's not my email address, that leaves password or configuration, right? --Password: According to Mr. Google's AI (*ahem*) I shouldn't use my regular password, I should use a "secure mail key"...well, that's okay, my regular password wasn't working anyway --Believe it or not, I've got notes on my original secure mail key so I enter that. Doesn't work. I enter the random character string that the secure mail key is supposed to stand for. Doesn't work. --I generate a fresh secure mail key in case the silly things have a shelf life. The new one doesn't work, nor does its random character string. --I then direct my attention to the configuration. Thunderbird said it knew what to do, but...what if? Inbound looks okay, compared to the settings on my old PC and also as recommended by Mr. Google. --Outbound...uh, oh...

Folks, I've tried every permutation that I can think of for passwords and outgoing servers and, lacking any intelligent guidance as to exactly what the problem is, I have no idea what else to try.

I'd appreciate advice as to what to try next, but am no longer hopeful. I may have to move on to another program in an effort to get something that works. I'm falling behind on my day.

Spoiler alert: Don't tell me to curse at the screen or give it the middle finger...I've already tried those approaches and they don't work.

Thanks, Grey

Before the last update, when you assigned a colored label to the message (e.g., work, important, etc.), the entire title, header of the message, took the chosen color. Now you only see a small tag.

'The previous system was definitely more practical. Can it be reactivated?

Hallo und guten Tag,

ich habe für Windows [PC] und Android [Pixel 8pro] jeweils die beiden aktuellsten Versionen von 'Thunderbird x64'und 'Thunderbird: Free Your Inbox' installiert und eingerichtet. Es sind zwei E-Mail-Konten mit jeweils einer Alias-Adresse eingerichtet, alles unter GMX.NET , IMAP+SMTP sind ebenfalls aktiviert [IMAP port993 und SMTP port465]. Leider bekomme ich es nicht so eingerichtet, daß Mails wenn sie am PC oder am Pixel empfangen und verschoben oder gelöscht oder als Spam markiert sind, daß dieses dann auch am jeweils anderen Endgerät so erscheint. Es werden immer wieder alle Mails neu als eingegangene Nachrichten gezeigt und ich muß dann am jeweils anderen Endgerät die gleichen Aktionen vornehmen.

Wo liegt der Fehler, was muß ich tun um das Problem zu beheben.
