I am looking to create a local folder where I can archive my emails to a different drive. Lets call that drive D: for now. I want to setup in "Local Folders" A folder called "Archive" and I want that to reside on the D: Drive But want to keep my email accounts that all emails come into initially on the C: drive till I move the emails to the "Archive" folder that is on the D: drive. How do I do that? It does not seem to allow me to change the location of the folders in "Local Folders" When i create one.

Any help, Helps... Thank you

I've just resumed using Thunderbird, with a new installation on a new computer, after a long period of having only my ISP's web interface. I'm having a problem with adaptive junk filtering: it thinks everything is junk until I tell it otherwise.

By default, it leaves putative junk messages in the Inbox, but displays a yellow ribbon above a junk message's preview with "Learn more" and "Not junk" buttons. In this configuration, having it assume everything new is junk is just a nuisance.

But eventually I will finish training it, and I'll want it to move junk to the Junk folder automatically. Then this behavior will be a disaster.

Using made-up numbers to illustrate, suppose I get 1000 messages per day. Of these, 998 are from addresses it recognizes, so it knows that 993 of them are junk and 5 are legitimate, because I've received email from those addresses before, and I've told it what to do with them. That leaves 2 messages which may or may not be junk.

It should leave those messages in the Inbox, preferably with some kind of warning, and let me decide whether they are junk or not. Instead it's going to move them to Junk, and I'll never know I got them unless I review all 995 new messages in the Junk folder... which would defeat the whole point of having a junk filter.

Is there a way to make the junk filter default to "not junk" when it doesn't know? I've looked at the configuration dialog, and I don't see one.

Hi

Last week we started having issues sending emails from our Thunderbird account (Optus email). When you go to press send we see a Add Security Exception pop up. When I click View we see the Issuer Name is DigiCert Inc. When I click Get Certificate it says No Information Available. We checked the SMTP setting with Optus today and they are correct.

Description: Optus Account Server Name: smtp.optusnet.com.au Port: 25 Connection Security: STARTTLS

If anyone has any ideas that would be great. Thanks Alysha

Using 2025-04 Cumulative Update Preview for Windows 10 Version 22H2 for x64-based Systems (KB5055612) Firefox 138.0.1 (64-bit) and says it is up todate. I have looked at the about:config to find the browser.tabs.remote.autostart but it does not exist in the list of processes. I have also unchecked in settings both performance options intermitently to try and correct this problem, but nothing happens: (unchecked) Use recommended performance settings Learn more These settings are tailored to your computer’s hardware and operating system. (Unchecked) Use hardware acceleration when available Nothing pops up to allow choosing a different number as many support articles say. I have AdBlocker running as an add on and turned off the duck duck go privacy essentials and still nothing stops these insane amount of processes clogging up my computer. right now, on this page there is only this tab open and there are 13 processes running. Please send real fix instructions- thank you

Hi,

Outlook user here moving to TB. Have exported several large .pst folders + sub-folders using third-party software' into several corresponding .sbd folders.

Success in TB to point individually to each one of the .sbd folders with the Local Directory address, each shows the sub-folders and mail as expected in the Local Folders menu of TB. However, the Local Directory address (Account Settings) seems to allow pointing only to a single folder with properly configured .sbd designation.

If I point to the root folder containing several individual and properly configured .sbd folders, none are recognized.

There is an Add-on called LocalFolders that would seem to solve this problem by allowing as many local folder locations as needed, but it's not compatible with current versions of TB. I wonder if TB will embed a function allowing for more than one local folder address, or having it be smarter in recognizing compatible folders within a single directory location rather than directly pointing at an .sbd folder. Adding new folders to Local Folders is not what is needed in this instance.

I have had an issue for quite some time now where I cannot set any details on my email addresses from the Account Settings screen on my Thunderbird install.

This has been an issue for quite some time I believe. The significance of the issue is that I cannot change SMTP servers because not only is the setting blank but when I select another SMTP it returns to default every time.

128.9.0esr (64-bit)

Please help! I am having to use a secondary email address for some of my clients because I cannot set up an SMTP server for them.

My 'sent', 'All Mail', 'Spam'; and 'draft' and 'templates' folders in my gmail account in Thunderbird have suddenly disappeared My other account looks fine, as is my husband's account I have deleted the account from thunderbird and reloaded it but it remains the same. My gmail account on my ipad and iphone still have the all correct folders in place Can you help please - ?

How to remove thumbtack icon from quick link icons on the homepage of Firefox.

The little thumbtack icon was by the name of the quick link on my home page. I updated to 139.0.4 and now thumbtack in top left corner of quick link icon. I want the thumbtack gone.

I am transferring my thunderbird folder to a new computer and it is 235 GB. I dont understand why it is so large. Are ALL my emails being saved? How do I delete so I can make smaller??

Witajcie, Mam pytanie. Czy jest jakieś ustawienie lub dodatek do Thunbirda, który odpowiada za eksport i import filtrów wiadomości (i tylko o ten element chodzi). Chcę skopiować filtry wiadomości z jednego konta (nie wiadomości) i wkleić do kilku innych (w jednym programie), a także skopiować je na dwa inne komputery i inne konta. Dotyczy to też strukturę katalogów (nie wiadomości) do których przypisane są filtry.

On Firefox Nightly 140.0a1,

The navigation bar (forward, back, tabs) is gone. I did not change any settings. Clearing cache, reinstalling, switching to the standard Firefox app did not bring it back.

Hello! I have used Thunderbird for many years. Lately, it waits much too long to prompt compacting all accounts. When "Compact all folders when it will save over ..." is set down to 1MB total, it still does not prompt until it has to clear 30 or 40 MB.

It didn't do this in the past, prompting me every 2 or 3 days at higher settings. So, I'm curious if this is "normal" now and I need to manually compact, or if there is a problem with 'Account Settings > Disk Space > Compact all folders' ... ?

Hello, I have an Outlook.fr account and I can't import messages from it into Thunderbird. Here are the installed settings: 1° IMAP = outlook.office365.com Port: 993 Connection security = SSL/TLS Authentication method = OAuth2 2° SMTP = smtp.office365.com Port: 587 Connection security = STARTTLY Authentication method = OAuth2

When I go to Outlook.fr via my browser, I have no problems accessing the Name account (Mail address + Password). What do I have to do to make it work? Thank you for your reply. Have a nice weekend.

Dear Support!

In order to index Thunderbird Emails in Copernic Desktop Search software, I need to install the “Thunderbird Connector for Copernic Desktop Search” in the Add-on and Themes menu. Unfortunately this Ad-don doesn’t seem to exist. Can you please suggest a solution?

I used troubleshooting mode and now my fonts and columns settings are gone. I had replaced Recipients column with From and Recipient in all my mail folders (I have lots). And everything looks different now. Different fonts and smaller text size everywhere.

How do I get my previous settings back?

BTW, the Troubleshooting Mode dialog is confusing. It didn't seem to do any thing until I checked a check box which followed the blurb about making the changes permanent. So I may have accidentally asked it to make them permanent. Not sure because the UI was unclear what it was asking me to do. Why are there 2 separate dialogs popping up? Do I have to tick something to make it enter TbS mode? Not clear. (I am technical but not about the internals of TB.)

I do have backups of my TB folder but I would need direction as to what files I would need to restore.

Thanks!

Why is there in about:config no reference to documentation of the displayed settings?

e.g. browser.chrome.toolbar_tips.hide_on_keydown

What is it? What is the meaning of the values? What is the default value? Why do we have to guess?

It is probably documented somewhere (I hope). Why is there no reference to it in about:config?

I checked the settings multiple times. The settings you see in the screenshot are correct. These are the settings I've used for the past 10 years. No problems until now. I just logged in today and Thunderbird did not want to work. K-9 Mail works just fine on all my Android devices. This is happening only on Thunderbird desktop.

• To troubleshoot the problem, I first removed the account and added it back. That did not work. • Next, I uninstalled Thunderbird and installed it back. Same problem persists. • This time I uninstalled Thunderbird using Geek Uninstaller to remove all related cache. Install Thunderbird back and try again. Did not work. • Read A2Hosting article a bunch of times: https://www.a2hosting.com/kb/getting-started-guide/setting-up-e-mail/accessing-e-mail-accounts-with-client-applications. Confirmed, all my settings are correct. Thunderbird is still not working.
