Thunderbird Support Forum

I would like to hide the "Switch to the calendar tab" and "Switch to the tasks tab" toolbar buttons that appear in the Thunderbird 91 top bar (title bar?).

I've tried the methods suggested for prior Thunderbird versions that employ userChrome.css, and they do not work.

Is it possible to hide these toolbar items?

Running 91.9.1, W10. At about noon today I stopped receiving all emails from multiple providers. I have done no updates. Selecting any account results in the looping timer. The mail is available at gmail and aol as well as on my iphone. I've restarted Thunderbird to no avail. All network settings look good. I am running windows defender. As stated I have changed nothing on the PC.

Has anyone received this message or know how to fix the issue that may be causing it?

The reason for the problem: 5.3.0 - Other mail system problem 554-'5.4.14 Hop count exceeded - possible mail loop ATTR34 [BL0GCC02FT003.eop-gcc02.prod.protection.outlook.com]'

For years when I compose an email, my address book appeared on the left column.

Somehow today it disappeared. How can I get it back to the above location when composing an email?

I did a clean install for my PC, Installed Thunderbird, added my mail account, checked "save in manager" after entering my password. After restarting the prompt keeps appearing after starting. The Password Manager has no saveds passwords.

I tried deleting cert9 and key4 and session.json, none of those helped.

After updating Thunderbird to the new version 91.9.1, most of my email messages disappeared.

An error message was displayed after updating to the new version. Thunderbird restart chashed and I started the program again, just to noticed that the messages were not anymore in the folders.

How can I recover my messages?

I am evaluating TB and the integrated calendar. I had no problem installing mail and calendar in terms of synching, mailing, and receiving except one: The calendar page will not refresh unless I hit the Hide/Show eye icon next to the calendar. Sometimes it also shows if I toggle from Today to Week.

Calendar properties do not show any options at the bottom for refresh cycles (see attachment). Other specs are below.

This is a show stopper for me, since appointments that were transferred but not showing are of no use. Please advise.

Thanks, Michael Clifford Details below

Hi!

I often send an email to 140 recipients via SMTP. Until recently it took 2-3 seconds. Now it takes about 2 minutes. My web-hosting company Simply.com is very insistent that their server is not the problem. I use TB 91.7.0 (64-bit) on Ubuntu 20.04.4 LTS. I am not sure whether TB updated itself when the problem started. Any help would be appreciated.

I'm new to PC's. I have very basic knowledge of how to use an i-pad. A month ago I got myself a new MacBook. I installed Thunderbird, no problems. My old mail showed up, new mail came in. I installed GNupg.

Following FSF's excellent tutorial I set up Thunderbird with encryption, all good. Now I'm at the point where I 'should try it out' by sending 'Edward' my public key. This worked as I immediately got an encrypted e-mail from 'Edward' in my Apple inbox. However, on Thunderbird I was left hanging with a constantly spinning disc which I presumed meant Thunderbird was trying to retrieve said e-mail. This did not resolve.

After clicking here and there on Thunderbird's interface, I ended up at the account set up screen being prompted for my e-mail address and password. Three weeks had passed and I couldn't remember my password, nor find a note of it. I only have access to account set up and homepage. On homepage I looked through the 'hamburger' menu but I can't find anything that helps. So, I'm locked out of Thunderbird mail.

Any help would be appreciated on both how to resolve the password issue, and what might have gone wrong in retrieving 'Edwards' mail.

Many thanks, Darren.

Hello,

So, my company want to trash their Exchange server for Gmail accounts. Welp, OK... but Thunderbird (last version) doesn't cooperate.

I tried to add a new account with the correct information. I set the IMAP/SMTP of Google as this is an other domain, SSL connection and OAUTH2 on both servers as needed. The Google window appeared, login and password is fine, I clicked on Authorize.

But Thunderbird doesn't want to create the account because of a sudden login/password issue.

The login/password is fine, I tried it on the browser and I did succeed the OAUTH2 process so this is not the issue. The Google account states that Thunderbird is indeed authorized.

Cookies are authorized.

I tried to change the password for something more stupid.

Heck, I even recreated a new profile without changing anything. In desperation, I even tried using the standard password method after activating the Less Secure Application in the Google account.

Thunderbird still refuses to connect to this account, with the same login/password error.

I don't get it.

Does someone have a solution before I shoot this retarded bird ?

Cordialy,

I bought a new laptop because the old one died. Now I tried to transfer my TB data into the new computer. I managed to do it BUT... only one of my two MAIN folder data is there.

Last time I needed to do that when my laptop died it worked. Now despite me using the EXACT profile path/name (eg, C:\Users\XXX\AppData\Roaming\Thunderbird\Profiles\XXX) in TB's local directory at my new computer only one MAIN folder's data is present.

Does anyone know how to solve this issue?

Thank you!

Many years ago, I had two computers receiving email. Both received a copy of each email.

I am attempting a move from my old Thunderbird (38.5.0 in Windows XP) to a new 98.9.1 in Linux Cinnamon Mint. I sent an email to the mailbox. It was received only by the new Tb. I shut down Tb and restarted it. I sent a second email. It was received only by my old Tb.

The server settings are: Check at startup, Check every 10 minutes, Automatically download, Leave messages on server, Until I delete them."

I can find no option to allow the email to be downloaded by two Linux versions of Thunderbird, though surely that must be routine for those who receive their email both on a computer and phone. I need a POP solution, since I can be away from either version of Tb for some time.

Help, please!

Hi,

I have a Mozilla Thunderbird email client, which has been linked to my Microsoft Outlook account using IMAP for years, and has operated perfectly well for my personal preferences.

At some point overnight (26th / 27th May) this stopped working and I am now presented with the error message "Sending of password for user xxx@xxxxxxx.co.uk did not succeed. Mail server outlook.office365.com responded: Logon failure: unknown user name or bad password" when trying to download mail.

This is very strange as I can log in directly to my Outlook account using the same user name and password. No settings were changed by me in either Mozilla or Outlook.

For information, I can still send messages from Thunderbird but not now receive them.

Can anyone help, please?

Many thanks.

All the posts suggest

 Please see https://www.mozilla.org/en-US/thunderbird/all/

but that just offers the latest version (current 91.9.1) which won't run on El Capitan.

Other posts tell you to look at

 https://www.thunderbird.net/en-US/thunderbird/releases/

but that only gives you the release notes for the older versions, without any download links.

How do you get the older versions?

Hi,

Couldn't find this in Preferences or Settings: How do I forward emails so that all the details of the message to be forwarded are NOT automatically there? I mean the message itself can of course be there, but I don't want a two meters long table with info such as the details below:

Return-Path: Delivered-To: Received: Authentication-Results: Received: ARC-Seal: ARC-Message-Signature: ARC-Authentication-Results: Received: Received: From: To: Subject: Thread-Topic: Thread-Index: Date: Message-ID: References: In-Reply-To: Accept-Language: etc. etc. etc.

My Thunderbird version is 91.9.1. Many thanks in advance! Laura

Copying the .thunderbird directory from old computer onto new computer no longer works.

Following instruction here: https://support.mozilla.org/en-US/kb/moving-thunderbird-data-to-a-new-computer is not possible because nothing happens when I click at this point: "On your destination computer Locate the "Profile Folder" entry, then click Open Directory."

Thunderbird is a Flatpak 91.9.1 (64-bit) Thunderbird-flatpak - 1.0 on Fedora-36.

Hi Mozilla Community I have attached a large-ish file 19.7 mb (a video) to an email. Pressed send and an alert comes up telling me I should use file share because ... and this is my issue .... the email is (now) 27 mb in size. I have updated Thunderbird, I'm using Imap and the TB version is 91.9.1 My computer is a two year old HP X360 laptop running Win10. I'm also using Bitdefender Total Security. I have tried several times with blank emails (no words) and a video attachment and some with just a few words and the attachment and also with other size attachments. Same result. This also happened with a 33mb pdf attachment, the alert saying the email size is 43mb I don't know where this extra 7mb or 10mb is coming from unless the alert calculation is wrong. Surely sending a blank email doesn't require this much data. I'm interested in others views and ideas. regards David
