I'm on version 148.0, dragging tabs stopped working, not on horizontal and not on vertical tabs I've tried to create a help ticket for it but apparently the help form just does nothing and doesn't send when I click submit Anyone else experience any of these issues? And how can you contact Mozilla even?

I had a Gmail address set up in Thunderbird on my old computer (Win 10). I had to get a new computer with Win 11. I have my Earthlink addresses set up okay.

But I've been unable to properly set up the Gmail address. I enter all the information, but the account vanishes from T-bird. All I have in Thunderbird is a Thunderbird Tab with Google info. It's a full page which might not come out clear with a screenshot, so I'm copying what's on this Tab ....

When firefox releases an update I find out when I try to use my browser for something. Im on the fly paying a bill and I want to get it done but oh its firefox update time and I dont have an instant choice stop that. I have first tell my security system that I dont want to make changes to my software at this moment I wanbt to use the browser for something important to Me. But still firefox wont let me. I have to wait till it processes my denial then comes the irritatin popup about download or dismiss and I have to respond to that wasting more critial moments for me then after a few more precious to me moments firfox will open and let me use it. This irritates the hell out of me and the worst part is if I dont waste more of my time performing the update when firefox chooses it will shanghai my browser all over again every time until I update. The worst thing is sometimes updates comie in rapid succession. Major irritation. How do I stop this? whats the work around here? I want to up date when it suits me not when it suit firefox.

Message Recieved:

• Fantasia I & II* Georg Philipp Telemann (1681–1767)

         Telemann’s Fantasias capture the brilliance and balance of the
         Baroque era—each movement a miniature world of counterpoint,
         grace, and invention.

• Kleine Passacaglia *Michael Kuntz (1915–1992)

          A modern take on a timeless form, Kuntz’s piece builds lyric beauty

Good afternoon.

When I receive emails such as password resets, or email verifications, etc., they always contain a line such as "click the link to verify your email", and they never display correctly like they do in other email programs, and I have to literally copy and paste the link in a web browser manually.

Is there a setting somewhere that I am missing?

This is what my messages look like . How do I get every line after "DATE" to not print like it used to. I am on version 115.10.1 My email is Fredwise@earthlink.net

In Firefox 148.0, I am encountering an issue related to input‑focus behavior on the default New Tab Page. I would like to confirm whether this behavior is now hardcoded or whether any configuration options remain available to modify it.

Issue description

When opening a new tab, Firefox displays a search box in the center of the page. In previous versions, this search box could function as a true input field. However, in Firefox 148.0, any attempt to type into this field results in the input focus being immediately transferred to the address bar (Awesome Bar). As a result, the central search box no longer accepts direct input and appears to function only as a visual entry point.

Configuration options already tested

Based on documentation and community discussions for earlier Firefox versions, I attempted to locate and modify the following about:config preferences:

• browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar
• browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar2

Neither preference exists in Firefox 148.0. I also reviewed other Activity Stream and URL bar–related preferences but did not find any that influence this focus‑handoff behavior.

Current observations

Testing suggests that Firefox 148.0 may have removed the internal toggles that previously controlled this behavior. The focus handoff from the New Tab Page search box to the address bar appears to be enforced at the application level, with no remaining user‑configurable switches exposed through about:config.

Questions for clarification

1. 1 Has the focus‑handoff mechanism for the New Tab Page been fully hardcoded in Firefox 148.0, making it no longer configurable through about:config?

1. 2 Is there a new or undocumented preference that restores the ability for the New Tab Page search box to receive input directly?

1. 3 Are there design documents, Bugzilla tickets, or release notes that describe the removal of the previous handoff preferences?

1. 4 If this behavior is now intentional and no longer user‑configurable, is using an extension (e.g., New Tab Override) the only remaining method to prevent focus from being redirected to the address bar?

Any technical insight or references from developers or community members would be greatly appreciated.

For 2 years have been trying to get Thunderbird to access my mail from The Messaging Co. My old Win 10 laptop has no problem. My new win 11 laptop won't. I have configured the servers over and over but everytime I try to access Thunderbird I get "could not connect to mail server: the connection was refused". Who is refusing the connection? And why? I have re-downloaded Thunderbird several times but the problem persists. I am using Firefox. And using the in and out servers as per my win 10 laptop.

Since to old add-on enabling customization of the message header toolbar doesn't work now, where might get one the is compatible with Thunderbird?

Thanks, James

Created new yahoo mail IMAP (PKCE) account using Thunderbird account creation. All seemed to work well. However, new account does not receive mail from "some" other IMAP and POP accounts in testing, including from TB Pro. Strangely, mail sent from oldest POP accounts works. Mail from newer POP gmail and TBPro accounts is not received. TB 149.0b1 Windows 11

Hi. From 27 feb I can't login to yahoo mail through mozilla thunderbird.

When I start thunderbird, new windows is opened with this link

https://login.yahoo.com/account/challenge/fail?src=oauth&client_id=dj0yJmk9WVZUaWRNUUZSQTBNJmQ9WVdrOVNqbHJUMGhtTkU4bWNHbzlNQT09JnM9Y29uc3VtZXJzZWNyZXQmc3Y9MCZ4PTgz&redirect_uri=https%3A%2F%2F127.0.0.1&done=https%3A%2F%2Fapi.login.yahoo.com%2Foauth2%2Fauthorize%3F.scrumb%3D0%26client_id%3Ddj0yJmk9WVZUaWRNUUZSQTBNJmQ9WVdrOVNqbHJUMGhtTkU4bWNHbzlNQT09JnM9Y29uc3VtZXJzZWNyZXQmc3Y9MCZ4PTgz%26code_challenge%3Dt6iqw87GVPZ649cCvOEh2L1hwkUluBhsrwxCdVTXAOY%26code_challenge_method%3DS256%26redirect_uri%3Dhttps%253A%252F%252F127.0.0.1%26response_type%3Dcode%26scope%3Dmail-w%2520ycal-w%2520sdct-w&acrumb=0EYriz7Z&display=login&authMechanism=primary&e=true&pcn=password&eid=3692

When I tried to login I see this information:

An error occurred.

We couldn't log you in. Please try again from a different device.

This is very strange, because I tried it on another PC and this is the same. It looks that yahoo even didn't try to check password, because this is not matter if I wrote correct password or different - I see the same information.

Please help. I have two yahoo mail account and this is the same.

Both accounts works well on another e-mail client and I can access to my account without any problem by browser. This is only thunderbird problem.

Hello Thunderbird Community Help!

After reviewing and implementing all the suggestions on the Mozilla/Thunderbird support pages and on the internet, I still cannot send emails from my office365 mail account from Thunderbird. I was able to send/receive email messages until about 4-5 days ago. From several different accounts on my laptop. And from two different laptops: one using Windows 10 and the other 11. Now, both will receive emails to their inboxes but neither will send a message.

I have the various set-up parameters set as recommended for SMTP using Oauth2, see below and the attached photo:

Outgoing (SMTP): Server: smtp.office365.com Port: 587 Security: STARTTLS Authentication: OAuth2 Username: Your full Office 365 email address

I have deleted the stored password hundreds of times. I have deactivated MFA with Microsoft. I have deleted the e-mail profile in question many times, and have re-created it using automated and/or manual configurations. And I have deleted stored passwords.

I keep getting this message:

"Login to server smtp.office365.com with username [my.email.address] failed." With three button choices: "Retry" "Enter New Password" "Cancel"

No luck with Retry or Enter New Password. They both result in a brief, failed re-attempt to send the email message, and a return to the previous message and choices.

Pressing "Cancel" results in this message: "Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) . Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'."

Additionally I've reset my MS password several times. And MS seemingly is uninterested in having TBird/me login to my office365 account. I just get this response repeated over and over:

"Login to server smtp.office365.com with username [my.email.address] failed." With three button choices: "Retry" "Enter New Password" "Cancel".

I've spent a LOT of time over the past few days and over the weekend looking for a solution, but nothing so far has worked and I'm at my wit's end!!

Any help that you folks far more experienced with TBird can give me to get things working again would be GREATLY appreciated.

Best regards...

Tony

I updated to the newest version of Thunderbird. I was having problems authenticating the accounts I have set up (I was required to do this after the update), but finally succeeded. Two of my accounts do not show all of the folders that are in those accounts. The other accounts are fine. When I try to subscribe, the missing folders do not show up even after refresh. The folders are in the web interface for those two accounts, and also show up fine in my phone. I removed the accounts and re-added them, but the folders still do not show up. The two accounts (Frontier) are hosted by Yahoo. I also have a regular yahoo account and those folders show up fine.

Just reinstalled and re-setup Thunderbird. This morning, a window popped up on my desktop titled: Activity Monitor. Never seen this before. Did I turn on something to make it appear? Can I turn it off?

I was cleaning up my wife's email when I noticed there are a lot of messages unread and in the trash folder that ought not to be. I am wondering how to fix that for her. Example: some amazon.com emails about orders, or emails from favorite merchants or websites.

hi today thunderbird started showing yahoo popup login and after adding credentials i always get "something went wrong.We could not sign you in. Try again from a different device." Also popup once closed it opens instantly.

i can sign in normally from browser. thunderbird version is 147

is there any fix about this?

thanks for any help

regards

I have used Thunderbird for many years and and have loved it. However, recently my "Local Folders Inbox" have been extremely slow (deleting emails, reviewing an email, etc.). I have tried every suggestion that I have found without any change: reducing emails in the folder (down to about 75 remaining), compacting and repairing the folder, deleting and rebuilding all of the msf files and global database, disabling all addons, empty trash and junk, clear the cache, disable hardware acceleration, exclusion in antivirus, etc. It has become very frustrating. Any suggestions would be greatly appreciated.

TB on Windows

Prior to TB 148, OAUTH worked for POP3 access to: Gmail, MS Outlook, and Yahoo.

After TB 148 upgrade: OAUTH to Yahoo fails, subsequent log-in page also fails. Both OAUTH to Gmail and OAUTH to MS Outlook still work fine.

Rolled-back/Reverted to TB 147.0.2 -- OAUTH to all works fine, as it did previously.

Note: YahooMail seems to have other problems. But I was able to confirm successful OAUTH and POP3 to YahooMail after reversion to 147.0.2.

I have an outlook work email account in Thunderbird. Now I need to add another for a charity role. The first/work one is fine, but I can only receive emails on the second/charity account. I've tried different setting for the outgoing server but I don't really know what I'm doing with that - can you help please? Thank you.
