I am troubleshooting a problem that arose after I migrated a Thunderbird mail account from an old Win10 64-bit PC to a new Win11 64-bit PC.

I installed TB on the new machine and opened the program without doing anything else, then closed the program. TB created installs.ini and profiles.ini files, both with the following as the last line:

Locked=1

This line had not been in either .ini file on the old installation.

I edited these files to point to the backed-up TB profile from the old machine, but I decided to leave the Locked=1 line in the .ini files.

Was this a mistake? I have a strange problem with the new installation, which I won't report until I understand what the "Locked=1" means, and whether I was ill-advised to leave it/them in. Fortunately there has been no evident loss of mail data.

Thanks in advance, Phil

I had an TB account with Spectrum but lost it when I didn't have Spectrum anymore. I got Sprectrum as my internet provider and am trying to create a new TB email account but have not been successful. Can you help me

I tried to connect to an existing Google-Mail account via 'new', 'existing mail account' etc.. Finally a Google-Login-Window appears. After inserting the username Google responses with a message, that my browser does not support javascript. However, both in thunderbird and in firefox javascript is enabled.

How do I change the ::selection background css for text that appears in the mailnews reader and editor views? I am happy to use userChrome.css or userContent.css. Currently the selected background is too dark against my chosen dark background color. I simply need to lighten it a bit. I've been through the about:config pages looking at "color" and there isn't a setting I can find. So it appears I will need to use CSS in userChrome.css to accomplish this. I need to know what the magic incantation is to do this. I get it will involve the ::selection pseudo-element, but which tag to apply it to, any special namespace? All?

An example of the selection color I am talking about is shown in this image (attached)

Preferably, this solution should continue to work when openSUSE updates to 136/7, etc..

I have been using the Thunderbird email client on my Mac for a long time to access my corporate Gmail account. (This is not a personal Gmail account, it is a corporate Gmail linked with Okta.)

In this corporate Gmail account, I do not have access to "App Password" settings or "Less Secure App Access" options. Everything was working fine until 25th April 25. On that day, I updated my Okta password, which also affected my Gmail account because Gmail is connected through Okta.

Since then, my Thunderbird email client has stopped working. It keeps asking me to allow Thunderbird to access Gmail, and even though I allowed it many times, the same pop-up keeps appearing. To troubleshoot the issue, I have tried the following steps:

• Reset my Okta password again to rule out any password issues. (I am able to log in to Gmail successfully with the new password and I can configure the same Gmail account with the Mac Mail app without any issue.)

• Upgraded the Thunderbird client to version 137.0.2.

• Cleared saved passwords and cleared cookies. (Note: "Accept cookies from sites" is enabled under Web Content settings.)

• Deleted the account from Thunderbird and tried to re-add it.

After this, I started getting the error: "Unable to log in at server. Probably wrong configuration, username, or password."

• While adding the account, I entered my name and email address, left the password field blank, unchecked "Remember Password", and filled in the configuration manually.

When I clicked on "Re-test", it detected the server settings correctly. But when I clicked on "Done", I got the same error again.

• Created a completely new profile in Thunderbird and tried again, but still faced the same issue:

"Unable to log in at server. Probably wrong configuration, username, or password."

• Uninstalled Thunderbird completely and reinstalled it, but the issue still remains. (Please refer to the attached screenshot.)

• I tried the troubleshooting mode, which disables all the add-ons and themes, but the issue is still the same.

Any help would be appreciated.

I'm not sure if this is relevant, but Gmail has made some changes (see the link https://support.google.com/mail/answer/7126229?visit_id=638814378228955739-1844270273&hl=en&rd=1). This might be causing the issue, though it was working fine until I reset my password on April 25th.

I successfully subscribed to an online .ics file but I found the resulting calendar entries inadequate and I want to unsubscribe but I can't figure out how to do that. I've tried searching for instructions but haven't found any.

Something like this question has been asked so many times, searching for other's answers has become useless. The answers vary over the years and Thunderbird version numbers, not to mention that I can't even find documentation from Mozilla on this topic (official method of changing font size for average user; official list of css keywords, their format, and examples of use; etc.).

I am trying to increase the size of the Thunderbird fonts—not the ones used to display an email, but the ones used to show my list of accounts, mailboxes, and folders and the list of emails I have received (Table View, not Card View). For what its worth, I've already changed the font magnification to 1.5x.

I set toolkit.legacyUserProfileCustomizations.stylesheets to true, and created a chrome folder in my profile directory. In it I put this userChrome.css:

/* Set font size in folder pane */ treechildren::-moz-tree-cell-text { font-size: 18pt !important; }

/* Set font size in message list page */ treechildren::-moz-tree-cell-text { font-size: 22pt !important; }

However, restarting Thunderbird (multiple times with various font sizes) shows no changes. What do I do to change my font sizes? (The average user shouldn't even need to know about profiles or style sheets!)

Hi All. Long time (25 years) user here, first time poster. Just want to report weird issue/bug, thought to start here on the forum: I'm a fast typer and often sending emails quite quickly. When I click 'reply' to a message, for example, I start typing pretty shortly thereafter. What I'm seeing in the past month or two (sorry, don't have accurate info on when this started) is that the focus briefly jumps to the 'to' field of my message before jumping to the body (where I think it should be from the beginning). The result is that I start typing my message (e.g. "Hello Gloria, Thanks for your email ...."), and get an auto-matched address from my address book (e.g. "He" matches to "Henry Yu") plugged in to the to: field. Then the rest of the text continues in the body field.

Sometimes I notice, sometimes I don't (if there are multiple recipients in particular it's harder to notice the extra address).

It's obviously undesirable to be sending messages to basically randomly selected addresses from my address book. Why is Thunderbird sending the focus to the to: field for a moment, and then jumping to the body? I suggest just putting the focus squarely on the body. Or, lock my keyboard or something until the message is ready to receive input.

Or would anybody know a workaround to this? Other than slowing down, which is of course what I'm doing at the moment.

I'm on Windows, T-bird 128.9.2esr (64-bit).

Thanks!

I just installed Thunderbird on Deepin Linux today. And I forgot which button I wrongly clicked. As a result, my thunderbird's appearance looks messy.

How to set it back to the default view without reinstall it?

I am looking forward to the answer.

I have been having much trouble with Thunderbird. The latest problem is with the Sent folder. When I try to Compact Folders I get the message "The folder 'Sent on Local' could not be compacted because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again."

I have plenty of disk space and have Full Control. I tried creating a temporary folder and moving all the Sent messages to it, so that Sent had zero messages. I still got the same message. The file listing showed Sent to have a size of 182 MB even though it didn't contain any messages. I've tried deleting sent.msf to force Thunderbird to recreate the index - didn't work. I tried using Repair Folder. That worked, but when I tried Compacting Folders again it found another folder with the same problem. I fixed that one and then it said the Sent folder was bad once again. I'm going around in circles!

I've deleted and recreated scores of .msf files for various reasons, trying to get Thunderbird to work without errors, but as soon as I get one problem fixed, another one crops up. I'd conclude that it's my computer, except that I'm not having any problems with other programs.

Any thoughts on this particular problem or Thunderbird problems in general? Thanks.

It appears that Thunderbird knows how much disc space is required to compact a folder, since it says there is not enough. Could the message say "You must have xxx free disc space" rather than having to use the trial and error method. If this space is 'work space' could Thunderbird be instructed to use a drive other than C: for workspace.

Greetings. TB crashes - It originally died after a short period of working. Managed to empty cache which seemed to have solved it, but then it came back with vengence and has given me no chance to explore as it won't load at all. I used to use folders for mail and also regularly compressed, however not the last few years. I also have a few Mozbackup files, but restoring a recent one of these has not helped. I am now finding it frustrating not being able to reach my messages. It is set up mainly as POP, with a number of different email addresses all reached through a common inbox. I have been using TB for decades and this is first issue like this. Glad of any suggestions. David

Just got a new pc with windows 11, I used the export from my older Thunderbird to create the file and it worked great, but I messed up when I installed Thunderbird on my new pc, I was so impressed (and curious) that Thunderbird could auto set up my email account, so I let it do it and it worked. I have 3 email accounts and when I used the import I thought it would overwrite the one it just created, but it didn't so I'm missing 3-4 folders I had on that one account It imported the other 2 accounts and folders great Is there a way I can get those folders from the old pc and copy over to the new?

I tried to uninstall Thunderbird from the new pc so I could do it right, only use the import function and get everything, but it doesn't uninstall much, everything is still there. Or is there another way? Thanks.

I recently moved to another email provider. Since the move I use a new email address (account). The mail in the previous used imap account must be saved. Since the old server at the provider has been blocked. A lot of emails have to saved for some years. Do you have a suggestion how to save the mail? Thanks, Paul

After 20+ years my email service has closed, and I have kept many old emails on Thunderbird. If I start reading an old email, a Thunderbird message pop up on screen every few seconds stating that it cannot connect to the dead email service. This is a real nuisance as the messages cover the screen over time, and each one needs to be separately deleted. Can this Thunderbird response be switched off?

I wish to keep using Thunderbird for the new email service, but only if I can fix this issue.

TB on desktop is set up for POP3 from my ISP. I found out there is a TB Mobile App for Android. How will this work as far as accessing my messages on the Mobile, but still leaving desktop on POP3? Can I have visibility of emails on Mobile, or do I have to change to IMAP? What about Local Folders, which I use extensively on Desktop.

Keeps on telling me it can't authenticate the outgoing SMTP server for both of my email accounts. Have checked settings and all appears to be in order. I do not want to re-load my accounts because the last time I did that I lost all of my messages because of being on POP 3 setting.

I (by mistake) tried go attach a file that was too big to send in a Thunderbird (gmail) message. Even though I click "Cancel" to the warning "Warning! You are about to send a message of size 29.6 MB. Are you sure you want to do this?" the warning reappears each time I open Thunderbird (and I have to close and restart it to have it send any e-mails). The offending message is not in the drafts or trash folders. How do I tell Tbird to stop trying to send this message?
