I am trying to install Thunderbird into a new computer with Windows 11. When I try to run, it goes to a configuration page but will not connect after finding my account. I have double-checked password, but it says "Unable to log in at server . . . ".

I have uninstalled and reinstalled new program, but get the same response each time. I want to install Thunderbird (and Firefox) and copy my profiles from my old computer to the new one. I am not able to do either. I have followed the online instructions for moving/migrating both, but neither work. Any suggestions?

I deleted a profile not knowing it would delete everything I had. How can I undo it? I didn't want Firefox Profiles, it was forced. I deleted it, and everything just got deleted. Can someone please help revert this? Thanks.

I apologize for the unhelpful summary line, but I am totally new to Thunderbird and the Unified Inbox is acting so strangely that I don't have any simple way to describe it.

Many (but not all) of the emails are displayed twice in the list of messages.

When I delete a message that isn't doubled, the message disappears from the inbox (as it should).

But when I delete one of the doubled messages ONE disappears as it should and on the other Thunderbird clears the From and Subject fields and changes the date to 12/31/1969, 19:00 -- the changed entry stays in the list and the body of the email is still shown in the lower pane. The only way I can get rid of the message is by selecting another folder (ANY other folder) then when I return to the Unified Inbox the deleted messages will be gone from the list.

I can't believe that this is how Thunderbird is supposed to work, so I assume I have something configured incorrectly (although nearly everything is still at the defaults that the installation gave me).

When I go to see a firefox bug such as the following, https://www.mozilla.org/en-US/security/advisories/mfsa2026-10/

There appears to be more details in https://bugzilla.mozilla.org/show_bug.cgi?id=2014390 located at the bottom. When I try to view the details it asks me to log in. I do not see any reason I should have to log in to view the issue as I only intend to view the bug. Why does it require a login ?

All my Tabs Group have disappeared from the Tab Bar. I can see the Closed Tab Groups in the drop down but i can't find a way to re-open Closed Tab Groups. Any clues welcome. Running 146.0 and on the beta update channel.

I closed 1 tab on my phone through the desktop synced tabs. Since then, Firefox has been continously sending me notifications about the tab being closed. I've clicked on the notification to open the app, but I still keep getting this.

Every time I open the new version the following comes up in a window. By agreeing, you’ll allow Thunderbird Mail to access: Yahoo Contacts read and write Yahoo Calendar read and write Yahoo Mail read and write

The Yahoo Contacts and Yahoo Mail I can understand, But, I don't want a Yahoo Calendar. Is it somehow possible to allow Contacts and Mail, but exclude Calendar?

I upgraded from windows 10 to 11 My son was able to recover my e-mail folders, but some large folders are missing and the remainder only have e-mails from 2019 or earlier. How do I recover those e-mails? I am no longer conversant with the current technology or terminology. I need simplistic instructions.

Since the latest update a Yahoo Mail sign-in keeps popping up...sometimes two different versions. It's driving me nuts. Should I uninstall/reinstall Thunderbird. It's so frequent for no apparent reason that I may have to give up Thunderbird and many, many years of use...and donations. thx, deanna

As stated above, received msg from me to me -- a common practice I hear. If I change my password, will that fix this? I tried to log in to Outlook on line to change password but I use a passkey - doesn't let me do a password entry. Help..... Thanks.

How to remove google search from the address bar on the right?????

I want to find my most visited websites in the address bar without any unnecessary actions!!!

I can't seem to locate how to activate the microphone in the AI sidebar. I have Gemini selected, and when I hit the microphone to dictate I get the following message.. Unable to access the microphone. Please check settings.

I looked through Firefox settings and my laptop's but I don't see where it is turned off or asking for activation.'

Since updating Firefox from a previous version, the browser no longer displays any Unicode emoji characters. Where an emoji would normally be rendered (👁️), the browser instead displays empty space. Websites such as twitter and discord, which use their own artwork for emoji, are unaffected. This has negatively affected my browsing experience.

For illustrative purposes, I will add a series of emoji and include a screenshot of how they are displayed: (😀🙁😡💀). Other characters still display correctly: (β❖♞䷲⎈𐘢𓀺இ). My computer otherwise displays emoji correctly. The issue persists after disabling extensions, and has persisted between computer restarts.

I'm running Linux (NixOS) and Firefox version 148. I've tested on Chrome based browsers and they work fine. Tested on Firefox forks and they also don't display correctly. This is new since less than a week ago.

Thanks for any help with this.

Previous solution: switch browser.newtabpage.activity-stream.improvesearch.handoffToAwesomebar to false does not work anymore.

Please help.

I use the same e-mail address on my desktop and my Samsung android phone. I was told to change my desktop e-mail from POP3 to IMAP which I did and then told by the Thunderbird desktop forum to change also my phone settings from POP3 to IMAP. I was told in order to do that I needed to create a new account first and then delete the old account.

However, when I go into server settings and I put in my e-mail address from my desktop, it states "e-mail address already in use". Clearly I do not want to create a new e-mail address - just use the same e-mail address that is on my desktop so that I can access e-mails on my phone that appear on my desktop. Help please!

At one time before several updates ago, all messages in my inbox were separate. After a previous update, reply or messages with the same header started be be nested, each one showing only the sender and the subject, which is now the same. I am forced to read through them all to find the one I want. Deleting any in the change can be hazardous.

How to go back the old way of message display?
