Thunderbird Community Forum

I installed Thunderbird 136.0.1 for Windows this week to use with my Gmail/Google account. I'm loving the way it works and the fact that it interfaces with the Google calendars (even the birthday calendar driven by Google contacts) well. The address book seems a bit more inconsistent with syncing/updating and I'm trying to gain an understanding of how that works. If I add a contact the the address book in Thunderbird, it shows up in the web interface in Google contacts. However, If I delete a contact in the web interface, that contact is not removed from the Thunderbird address book. Am I just not being patient enough for the syncing to take place?

Thanks! Rob

Sometimes I want to change the color of a single sentence in an email I'm composing. I get the Color Selection from the menu, but the text color remains black. (I don't have this problem with any other software I use, including a couple of "ancient" software tools.)

Please advise.

I accidentally selected "view" instead of "delete" for ~300 messages. On restart T-bird crashes before displaying the Inbox. I cannot now view any old messages. Is there a way to stop T-bird from trying to view the ~300 messages? Thanks.

Thunderbird generated a crash report but did not send it. I got "There was a problem submitting your report"

Yesterday afternoon emails suddenly stopped going out. I sent an email successfully at 2:18 p.m. At 2:57 p.m. I couldn't get anything to send. Today the problem persists.

I have not changed anything. My roommate also uses Thunderbird and has not had any problem. I've compared my settings to hers and they seem to be the same. I have closed and reopened Thunderbird with no improvement.

I'm using Thunderbird 128.8.1esr (64 bit). I'm including images of the error message and the server settings.

Thanks for any help. Nancy

I just created a new contact, and set their time zone to "Europe/Zurich". After saving the contact, I exported the CardDAV address book in vCard format from "https://carddav.OMITTED/addressbooks/OMITTED/addressbook/?export", the time zone just shows up as "Europe/". So either the form data is being handled improperly by Thunderbird, or the CardDAV server is handling it improperly. I'll also file an issue with sabre/dav in case the problem is with them.

The server (run by a third party) is running sabre/dav 4.6.0:

❯ curl https://carddav.OMITTED

< d:error xmlns:d="DAV:" xmlns:s="http://sabredav.org/ns">
  < s:sabredav-version>4.6.0</s:sabredav-version>
  < s:exception>Sabre\DAV\Exception\NotAuthenticated</s:exception>
  < s:message>No 'Authorization: Basic' header found. Either the client didn't send one, or the server is  misconfigured. Login was needed for privilege: {DAV:}read on </s:message>
< /d:error>

Suddenly my e-mails are showing in Thunderbird as tabs rather than listings. What have I done? How do I rectify it? I looked in display, and there didn't seem to be anything there to help me.

Thanks.

I have changed my passwords on 2 gmail accounts I import to TB. Usually when you do that and TB retrieves email from gmail, you get a credential popup because the password doesn't match. Usually when you get that popup you click "next" and put the new password in and everything works as it should. I have been messing with this for 2 days now. I get the gmail credential popup, but when I click "next" to continue, I then get an error 400 from google? You can't do anything else after that. That darn popup just keeps coming and coming every time TB tries to retrieve email. Anyone else having this issue and found how to fix it? Is it a TB issue or gmail/google issue?

Thunder quit downloading Yahoo email. I can still see my email online with Firefox. I have had the same Yahoo email connected to Thunderbird for 15+ years. Thanks

Running Thunderbird 115.10.x on Windows 10 Pro 22H2 on an older Samsung Note 9 Pro 15 w/ an 8th gen Intel i7, 16GB RAM and an aftermarket 1TB SSD w/ over 660GB of free space. I have emails going back to 1997 in the Sent folder (16K sent emails). While running Thunderbird 115.9.x earlier today, I noticed I suddenly could not delete emails out of my Inbox. The following error message was displayed:

The messages could not be moved or copied to folder 'Trash on [username@domain.com]' because writing to folder failed. To gain disk space, from the File menu, first choose Empty Trash, and then choose Compact Folders, and then try again.

So I did that to no avail. I then tried to delete messages out of other folders as a test (Sent, Drafts, etc.) figuring I could simply move them back if successful. Received the same error message. Closed all applications and rebooted the laptop as it had been running for several days. Same error message.

Did some research which all told me to delete the Trash MBOX files (including the .msf file). Did that, same result. Launched in Safe Mode, same result. Created a Trash.txt file, removed the .txt file extension and relaunched Thunderbird. Same result. Compacted all folders and relaunched. Same result.

If I backup the current folders and restore from them, I'll get the same result. Anyone have a new idea or set of instructions I can follow?

Thanks!

Hi I've recently started using Thunderbird & have made several customisations & created a userChrome.css file. I find the yellow star on a starred message a bit to easy to miss. Is there a way to either make the yellow star another colour or to make the starred message in the message list another colour (like Outlook does)? The only info I have found so far makes all stars change colour - starred on unstarred. That defeats my objective. Thanks, Tony

Last night (9/23/2024), Thunderbird began presenting a screen (see attached) requiring me to sign in to contine to Mozilla Thunderbird Email. At the top of the screen is a "Sign in with Google" line. However, there is nowhere to sign into anything. My correct email is displayed but no entry for a password.

Clicking "Next" takes you to an Error 400 screen. There is no "Close" button and the only way out of the screen is to hit "Esc," which takes me to my Email account. After a short bit, the screen refreshes back to that " sign in to contine to Mozilla Thunderbird" screen. After one or two more uses of :Esc, I can get back control of my laptop.

Meanwhile, Thunderbird is frozen--mail doesn't update, and any attempt to use T-Bird returns me to the sign in cycle. Win 11; TB ver, 128.2.3esr (32-bit); server security imap.gmail.com, port 993, outgoing server smtp.google.com, authentication OAuth2. I've accepted cookies and javascript and closed my VPN. can't figure what to do next.

I installed Thunderbird 136.4 (64-bit) today on a new windows 11 Pro PC. I created 4 - POP3 accounts. The 1 gmail address downloaded all older emails from the servers, but the 3 TDS email addresses only downloaded a couple of months of emails. I can't find a setting that will find and download older emails. I checked the online TDS accounts and they have years of emails on them. Anyone else have that problem? Is there a solution anywhere?

One day I tried to send an email, and it failed. This just happened suddenly without me touching any of my settings. When that happened, I researched reasons and have tried everything. It's an outgoing server error. I tried changing it to what my email provider and the internet says it should be, but nothing works. I even called Spectrum, and they said I needed to contact Thunderbird support.

Hi All,

Two days ago, my Google calendar sync stopped working. I tried to add them again, but now, for a change, I can't see events at all, even though Thunderbird plugins theoretically got access to calendars. Should I wait for an update? Is this a global problem? How can I solve it?

Thank you Mariusz

i did what microsoft said to do ran DISM and jhad to do my computer all over again losing all my passwords and sites i can not sign in to thunderbird or Xfinity and can not get a hold of anyone lost passwords to allimportant sites Please help with thunderbird if possible

I updated, then I un-installed, then re-installed Ver 136, but still no confirmation request. after shift -delete. Highlighted Messages were immediately deleted with no confirm message displayed. What do I do to reinstate the "confirmation required" prompt?

During my messing around while trying to solve a UI problem arising from a migration to a new-to-me used Mac, I found a way to change the font size in the "Subject" field of e-mails in their own window, and as an experiment made it larger. It did not change the other problem, which has been solved.

Now I can't re-find that place in any of the settings, and want to change it back to the default. Please, someone, anyone, where is it?

Using TB 136.0...
