I can't seem to get Thunderbird on Linux Mint to work. Everything font related is a mess. I don't know what default Thunderbird uses when it doesn't know a font but the setting is unreadable. I've messed with a ton of font settings but nothing seems to change anything. Note if I copy the garbage and paste it into a notepad, it is totally readable but there appears to be no way to change this default in Thunderbird. Please help.

after setting up a new install on another pc (ver148) and moving the profile folder over,

the only issue i have so far is the little yellow star in the folder for new mail having arrived in is not showing up. it will show the number of new msgs on the taskbar icon only.

can this be fixed?> can seem to see it in settings.

image attached of how it looks on the old pc

thanks

I have 2 accounts. One account is for my normal email address, which contains my usual "Name+Surname@gmail.com The second account is for a fake name (as used on this forum): oldgrantonian@gmail.com

In Thunderbird, my normal email address works fine.

But the last email in my fake email account was on 16/02/2026. I can't send emails from the fake account.

The online version (mail.google.com) is fully up-to-date. I can send and receive emails in both accounts.

I would be grateful for any advice on how to restart the fake account.

Thanks

I've been trying to move my Thunderbird data (148.0) from a Win10 to a Win11 machine. I've meticulously followed both the methods outlined at http://mzl.la/1ApHiU3. I have copied my original profiles.ini from the ...AppData\Roaming folder to that location on the new machine, then corrected the drive locations in the file (see attached profiles.ini image). (yes, the correct "j4sqsccb.XXXXXXX" folder is copied to the new installation's root: a bulky several-GB)

In order to try to replicate my original computer's admittedly-awkward installation from long ago, I have added the suffix " -p -no-remote" to the desktop icon's Target field. And on startup, the new T-bird does properly show my original profiles in the Select panel - even though I only ever used the one that functioned correctly, identified as 1 in the profiles.ini file (see Choose User Profile image, IDs X'ed-out).

However, on selecting that profile on the Win11 machine, Thunderbird just takes me to the account setup screen, as if it's unable to locate or load the account settings for that profile.

I'm only doing this clunky method of copying-over out of ignorance; I'd be very happy to simplify the mess I'd created decades ago with my original installation. OR if you think I'm better off wiping all evidence of past installations to start from a clean install, I'll be happy to do that. Please let me know if you need additional info I've failed to provide here!

Also adding images of my ...Roaming\Thunderbird\Profiles folder and Installs.ini file, just in case!

hello, i cannot seem to find a solution online, hopefully someone can help.

i often receive emails with images attached, and most of the time people don't resize their images. you can imagine over time this all adds up in the email storage folder total size.

i dont always need to keep a 6mb image version, it can be reduced after i am done.

i would like a method to resize the received emails image attachment, to at least still have a smaller copy for refence, but not end up with a huge thunderbird email account profile (in the email received not externally saved)

preferably a one click solution, or even a routine i can run on the file system, etc. or some way to edit the received email and its attachment in program.

thanks

Why am I not able to add a 3rd IMAP email account?

Everything comes up like before for IMAP accounts, but it does not recognize the email or password, for some reason, and I have checked them over and over.

I also tried adding manually, but although it adds the email account name, the connections don't work, and there is not much information to even adjust that.

Have been using Thunderbird and Firefox for decades, naturally, and have several email accounts. Within each account, I'm a prolific user of folders within the respective Inboxes. For years, these folders have remained in Alphabetical Order, as when they were set up. Recently, however, for no reason that I can suss, the sub-folders in the Inbox of one of my accounts have been gone "all agley", ie. they're listed all higgledy-piggledy in random order. This isn't a problem for my message filter - but it's a real problem for me, having to scan down a very long, disorganised list to find any particular folder I want to open. I've searched for an instruction to instruct Thunderbird to arrange the Folders in my Inbox in Alphabetical Order and can't find anything. Can anyone help me, please. Many thanks in anticipation to all you helpful Thunderbird Users and Contributors. Cathleen (London, UK)

Hello, I’ve just started using Thunderbird and I really like it so far.

I have one question regarding attachments. In emails that include attachments, is it possible to change how the attachment area is displayed? Currently, it appears as a single line at the bottom of the message. Ideally, I’d like to have it displayed more prominently, preferably at the top of the message, similar to how it appears in Outlook.

So far, the only adjustment I’ve made is setting mailnews.attachments.display.start_expanded to always show attachments expanded. Are there any other settings or methods to further customize the attachment view or position?

Thank you in advance.

Before I recently (& reluctantly) upgraded to TB 140.8.1esr, I used to be able to paste the following in the Error Console to get a URI for an email message (or template) that I wanted to access from my calendaring app (EccoPro -- yeah, I know, one of those "from my dying hands" things, but it has never been equaled much less surpassed, just choked in the cradle by MS Office).

var hdr = gFolderDisplay.selectedMessage; alert(hdr.folder.getUriForMsg(hdr));

I would highlight the message I wanted to use, hit Shft-Ctrl -J, and paste that in the console.

I would get a notice with something like this which I could copy

"mailbox-message://nobody@Local%20Folders/Templates#10"

I could then put a clickable link in my calendaring app to run

"C:\Program Files\Mozilla Thunderbird\thunderbird.exe" -mail "mailbox-message://nobody@Local%20Folders/Templates#10"

That message would open. Then I could hit Ctrl-E to edit it, paste as needed, and send .

This worked very well. I did not come up with it. I struck gold with Google and just copied it. With something similar to AutoHotKey I was able to automate it.

Now those URI codes no longer launch at all, and I cannot get new ones because when I paste

var hdr = gFolderDisplay.selectedMessage; alert(hdr.folder.getUriForMsg(hdr));

into Error Console I get

Uncaught ReferenceError: gFolderDisplay is not defined
   <anonymous> debugger eval code:1
   getEvalResult resource://devtools/server/actors/webconsole/eval-with-debugger.js:306
   evalWithDebugger resource://devtools/server/actors/webconsole/eval-with-debugger.js:218
   evaluateJS resource://devtools/server/actors/webconsole.js:895
   evaluateJSAsync resource://devtools/server/actors/webconsole.js:788
   makeInfallible resource://devtools/shared/ThreadSafeDevToolsUtils.js:103

If I had known what I was doing in the first place, I might be able to adapt to this version of Thunderbird. Something obviously changed in how the Error Console operates or something.

Does anyone know anything about what command could generate a message URI so I could open it from another app using the command line?

Hi,

OS: Linux Manjaro 6.18.12-1 (Cinnamon 6.6.7) Thunderbird: 147.0.1 Email: google account

Everything worked perfect till I upgraded to version 147.0.1 When after replying or writing new email, hitting the [send] button I always get this error message

"Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.gmail.com timed out. Try again."

Click [OK] and save the message or messages is dropping them in the 'Drafts' folder. Close Thunderbird and start it again. Then double click the messages in the [Drafts] folder and hit the [Send] button, will send the messages without problem.

Nothing changed to my setup, I only upgraded to 147.0.1. Another weird thing: every-time I start Thunderbird it creates a Thunderbird directory under my home.

Is one connected to the other? Has somebody an idea what's going on/wrong?

Many thanks in advance

My desktop win 10 computer system crashed. While the operating system was zapped, the actual c: drive was intact. A new c: drive was installed with win 11 pro but when I connect the old drive to the new system, I am locked out of the user>apps>thunderbird folders ( access denied). Is there a way of overriding this security feature? I was hoping to be able to import my profile with several email addresses and their associated archival data. This is more complicated than I was expecting.

When I am typing an email in Thunderbird, regardless if I have my font size preset to Extra Large, Large, or Medium, the font that appears in the email while I am typing the email, is very tiny, so tiny it is hard for me to read it. Yet when the email is received by the recipient, the font appears the correct size as selected in composition settings. How do I fix this?

I have a lot of saved address and want to import them from desktop to mobile. All I can find is instructions to add them to my device phone contacts.

That is a no go. I do not want all those in phone contacts as they are irrelevant to phone and too many and too much clutter.

How do I get those into thunderbird ONLY not into phone's contacts?

If no possible can someone recommend a mobile email client that can do this?

Will thunderbird run on an iMac With a M4 chip? I’ve tried to move the app from an older iMac to my new one and all I get when I open it is a message that it’s corrupted,

We have been using the Brother MFC-J6940DW iPrint&Scan Attach to email successfully with Thunderbird. It creates a new email and attaches the scanned item to it. Recently it stopped working. Nothing happens and there is no error message. We have run all Windows updates. We have uninstalled and reinstalled the Brother drivers, uninstalled and reinstalled Thunderbird, downgraded Thunderbird to v 143 and 140 from current 144 version. We have confirmed Thunderbird is default mail app and verified in registry that Mozilla Thunderbird is default in HKEY_CURRENT_USER|Software\Clients\mail > (Default) value = Mozilla Thunderbird and HKEY_LOCAL_MACHINEISOFTWARE\Clients\Mail > (Default) Value = Mozilla Thunderbird. We have made sure the Firewall talks nice to the Brother Utilities and the ports are ok for Public and Private. Brother tech support says as long as we can do a normal scan that it must be Thunderbird or Windows. Does anyone have any thoughts or other troubleshooting ideas? Thanks in advance. -- Sue

Hi! Since I've installed Thunderbird on my new computer with Windows 11, I've now twice experienced the disappearance from my inbox of a bunch of emails. Never had this before with Thunderbird. Could it be something needs doing in Settings (I couldn't find any relevant options)? The emails weren't among the newest, but they were all important.
