Thunderbird Support Forum

I got a new laptop and transferred Thunderbird from old to new computer. Now the font for messages in my inbox is very small. How do I increase the font for the text of messages in my inbox. Was much larger on old PC. I have been able to increase font on messages I send, but can't find anyplace to increase inbox.

Thunderbird stopped downloading email for one account on 24/4/22, been working fine for years, 3 accounts set up on the one install and other 2 are still working fine. Updated to newest ver. then tried a fresh install on a seperate machine and exactly the same, downloads mail up to 24/4/22 and nothing after it. Set up on POP3 checked settings against others all good. When you do a download the bottom banner shows breifly how many new mails are on the server but it doesn't download them and doesn't show any fault!? Any help would be much apreciated.

what link do I need? I have a problem sending emails from Thunderbird & was wondering what link I need to direct my question to the right people who can assist

I do have an error message I can send you, but would like to know where exactly to send my question before I attach the error message. But I guess I will attach it to this message just in case you can help

Thank you

The Bruce Porter above is correct but as you can see the highlighted Email is wrong - it's actually for Stuart Zall!

I restarted Tbird in troubleshooting mode and that didn't help. Very frustrating to not be able to correctly sort by recipient (in my Sent folder) nor trust it really is the person I'm looking for!

Thanks, Kaarl

I don't actually have a problem or question.

In regards to Thunderbird, I was looking for a solution for a dark theme, and it lead me to a two year old answer that maybe out dated.

What I did find out i that the answer should now say to go to Add-On Manager, and usually a dark theme is ready to be selected.

I'm afraid people might not find it because they will try to follow directions that will only be frustrating.

My desk top has been turned off for 3 months as I was out of town. I am back and fired it up. When I attempt to send emails I get this error message

Sending of the message failed. An error occurred while sending mail. The mail server responded: Please turn on SMTP Authentication in your mail client. c-73-25-244-35.hsd1.or.comcast.net ([10.0.0.116]) [73.25.244.35]:57209 is not permitted to relay through this server without authentication.. Please check the message recipient "jmatthews@bhy.net" and try again.

Hello, My PGP key for one of my accounts stopped working while I was trying to draft a message. At first, the message said that my PGP key couldn't be located and thus my draft could not be saved (I believe I have all my drafts mandated to save as encrypted). I decided to delete the key from Thunderbird and try re-importing it. At first, it said the key had been imported successfully. However, when trying to select the key from my account page, nothing comes up. It's just blank. I quit Thunderbird several times and re-opened, only to get the same result. Now, after my most recent app restart, Thunderbird simply won't import my PGP key at all. Other accounts still have their PGP keys active, but not this one. I'm at a loss. Is anyone else experiencing this issue? Is this a new bug? I'm running the latest version of Thunderbird (91.8.0 (64-bit)) on macos. I've attached images. Please help! Thanks!!

Is there an add-on that would allow me to generate a tf-idf list of statistically significant words in a Thunderbird folder? Ideally, I'd like control parameters like:

1. search parameters (e.g. by date range, include/exclude addresses...)
2. number of words/tokens returned (this is less important: I can manually cut)

If not, has anyone seen something like gensim applied to Thunderbird folders?

I'm upgrading from windows 10 to windows 11. Will Thunderbird make the transition without problems? Same question for Firefox.

Will I need to completely reinstall and reconfigure Thunderbird and Firefox after the Windows 11 upgrade?

Hi! My beloved Mozilla program gave me an error message when trying to open it this morning :(

Error: Platform version 91.7.0 is not compatible with minVersion > = 91.8.0 maxVersion < = 91.8.0

Program won't open at all. Any way to resolve this problem? Or at least recover files? I've used Mozilla for years to organize important emails...clearly that was a bad idea now. Please help? Thanks! Lisa

My display name is stuck on "me", I really want to change it This glitch showed up recently, I believe when I "up-graded" to version 78.9.1 before that, it was my name. account settings  : "your name" shows my name, but all my e-mails show "me" instead of what is clearly written in the "your name" field really irritateing ! any suggestions ??

1. Some of my emails display BLANK content when opened; since Thunderbird updated with 91.8.0 to my Windows 11 64bit. The header displays correctly but the view screen is blank. I've tried troubleshooting in safemode and disabled any add ons, reset all the display controls and restarted with no success to resolve the problem. I've tried different view modes, Original, Simple HTML and Plain text and still get nothing showing. I've tried to copy the blank screen to clipboard to try different color modes with no luck. Not a problem of White on White text. The message is in there when I check the Message Source, but it does not display in the view. However the original mail does display correctly on my browser when viewed on my ATT email account which forwards to Thunderbird on my computer.

ODD Solution: i just noticed that when I move the email with the BLANK content to TRASH, then that content does display correctly! Then I can move that email back to my INBOX and it displays there correctly. Isn't that crazy? Ha,ha, the quirks of computers are like quarks in quantum mechanics with random results.

2. Some of my email content is displayed under the WRONG HEADER. The email content displayed under the wrong header is usually the content from the prior message. For example I get an email from CVS ok. Then my next Email is from Citibank, but that email displays the content from the prior CVS email. No solution to that as of yet. Are these BUGS in the new release 91.8.0?

Had to clean up hard-drive on Mac OS Catalina - erase, restore, etc and reinstall thunderbird. I have reinstated all my emails but apparently not my addressbook. I have a Time Machine backup that I've been restoring from. Where will I find my email addressbook and how to restore it? Many thanks.

TB has been working for years with 2 gmail IMAP accounts and Google calendar. TB has just updated to 91.8 and the gmails and calendar stopped working. I deleted the stored passwords, started TB in troubleshooter mode and re-entered the google passwords.

Google calendar is now working but the 2 gmail accounts still don't work.

I deleted one of the accounts from TB and re created from scratch. Account creation fails with

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

The other gmail account which I haven't deleted comes up with an authorisation error after entering the google password and allowing access.

I have checked that TB cookies are allowed and javascript is enabled.

I have run out of things to try.

What I don't understand is the calendar is working but gmail isn't even though they use the same Google account and password (and Oauth2).

I am using the latest Thunderbird 91.8.0.8126 and latest Firefox 99.0.1.8136. I am having the same issue as reported in these posts:

https://support.mozilla.org/en-US/questions/1343530 https://support.mozilla.org/en-US/questions/1344530 https://support.mozilla.org/en-US/questions/1350244.

I have 5 Gmail accounts that I manage for different family members. All accounts in Thunderbird access Gmail via IMAP, and are configured to login with OAuth2.

This week, Google removed Thunderbird access from 2 of the accounts, I do not know why. When I login to the accounts via the web in Firefox, Thunderbird was no longer listed under their 3rd party access. The other 3 accounts are fine.

1 of the accounts does not have 2FA enabled. I was able to re-login with Thunderbird when prompted, and I was presented with a window to grant Thunderbird access, which worked, no problem. So Thunderbird's browser was clearly recognized.

But the other account does have 2FA enabled, and that is where the problem lies. Thunderbird prompts for login, and the username and password are accepted, but when I enter the 2FA verification code, Thunderbird presents a window saying "Your browser is not supported anymore. Please update to a more recent one." (https://bugzilla.mozilla.org/show_bug.cgi?id=1677845). There is no option presented to grant access to Thunderbird. Yet, the verification did work, because my primary email receives notification that the account was logged in from a new device.

For the record, the failing 2FA account is managed by Family Link (the other non-2FA account is not). According to https://support.google.com/mail/thread/127545584/, such accounts cannot login to email clients. But that has never been a problem before, and 1 of the other still-working accounts in Thunderbird is also managed by Family Link and works just fine, so that can't be the culprit.

Also, I do have AVG installed with Email Shield enabled, but disabling that makes no difference.

Thunderbird's UserAgent is "Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:91.0) Gecko/20100101 Thunderbird/91.8.0". And yes, cookies are enabled in both Thunderbird and Firefox.

Is there a way to get Thunderbird to use Firefox properly for Gmail login, instead of its own integrated browser?

Hi It seem I cannot send Emails' it comes up with this message Sending of the message failed. An error occurred while sending mail. The mail server responded: [TPG-A02] Authentication denied. User jdeboer8@tpg.com.au is banned from using SMTP AUTH due to previous abuse. Please verify that your email address is correct in your account settings and try again.
