It has stopped working. Starting 2 weeks ago, Thunderbird keeps saying "Login to server imap.aol.com with username stuart_jones@verizon.net failed." I don't know what to do.

I use the android version of your email app. I love it, easy to use and almost use the "Unified" Inbox all the time.

It would be nice to nice to have this facility for any type of account.

Thanks

As described in [question] I am unable to install addons in Thunderbird: when attempting to install an addon, either via the in-app browser or via a file, a pop-up window appears for which "Add" and "Cancel" buttons do nothing (there is no way to move or remove the window without killing the process).

I am opening this question as this problem still persists over a year and many versions later.

Thunderbird V. 115.11.1-1 on 6.9.3-arch1-1 with Sway WM

No matter how many times I re-create the link, I cannot get my subscription calendars to either work at all or if they do they work very rarely. Forcing a sync doesn't help. I can see the same calendars just find online and in other calendars including but not limited to Mac OS Calendar.

Whenever I select an email in my Inbox which has attached files (of any type) i get this pop-up, one for each attachment. https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2024-07-02-00-10-20-f3ab8a.png This has only been occurring since I updated to Ubuntu 24.04 and Thunderbird 115.12.0-2 If I click on the "Find more in Software" button I get a message 'Failed to execute child process "Gnome Software" (No such file/directory)'. I have searched for a solution but can only find a reference which suggests that the problem has something to do with Evolution, (the file handler, not Darwin's theory). Any suggestions? Cheers Ian

Have a macbook pro. Have not updated firefox in a while due to this message I get when i go to "about firefox" "Updates disabled by your system administrator" This is my personal laptop for the last few years, nobody has ever used it. I AM the administrator. Many posts online about this message for windows and linux but cannot find a fix for Mac, or why this is happening.

How do i update please? Having a lot of latency issues of late so need to update.

I'm migrating Thunderbird from my old Windows 10 computer to a new Windows 11 computer.

I've installed Thunderbird v115.12.2 and successfully moved all my accounts, emails, calendars, etc., to the new computer.

Several things are NOT working correctly, though:

1 - Settings will not open. Here is the message from the error console:

Error: No such tab mode: preferencesTab

   openTab chrome://messenger/content/tabmail.js:758
   openTab chrome://communicator/content/utilityOverlay.js:257
   openPreferencesTab chrome://communicator/content/utilityOverlay.js:295
   openOptionsDialog chrome://messenger/content/mailCore.js:628
   oncommand chrome://messenger/content/messenger.xhtml:1

tabmail.js:956:17

   openPreferencesTab chrome://communicator/content/utilityOverlay.js:295
   openOptionsDialog chrome://messenger/content/mailCore.js:628
   oncommand chrome://messenger/content/messenger.xhtml:1

2 - Customize menu does not open

3 - The hamburger menu in the upper right corner does not open

4 - The spaces toolbar on the far left is missing

5 - Events and Tasks are missing from the menu

6 - My calendar is nowhere to be found - I can't find a way to access it (on my old computer, I clicked on the calendar icon in the spaces toolbar on the left side of the window)

Thunderbird on my old computer was also running v115.12.2 when I backed up the profile folder to move it.

I tried downgrading to Thunderbird v102. I had all of the same issues listed above PLUS all my accounts and emails disappeared. -- I've brought it back up to v115.12.2.

Could someone please help me get Thunderbird working correctly?

My wife sent me an email with a small word file to my Yahoo and I see the email when I log into Yahoo but not Thunderbird. I have always been able to receive emails with attachments before so don't know what to do. I'd be fine if I saw the email without the attachment but no email shows up at all in Thunderbird, only Yahoo email.

Hi, I’m trying to move from Outlook 2003 to Thunderbird 115.12.2 (64-bit). Using the import wizard fails. Tools > Import select Import From Outlook and the following message appears. “Either there is no default mail client or the current mail client can not fulfil the message request”. I’m taken back to the Import from screen with the addition of a red panel with “No Profile Found” on it. Outlook 2003 is the default e-mail client, checked more than once. I’m trying to migrate to thunderbird so I have no account setting, thinking they would be imported. My pst’s files have been moved to a directory on a different partition to the Outlook programme, tried creating a dummy profile using default Outlook storage and still fails. I’ve looked at converting pst files to mbox, but this doesn’t see to include the account settings. But I could add them manually or I can not import the mbox files or directory structure into Thunderbird. I’ve been messing around trying other things but nothing works. Internet searches, Thunderbird forum searches suggests solutions but all fails and the steps don’t match Thunderbird menu, etc in many cases. I’m stuck. Can anyone give any advice on how to migrate from Outlook 2003 to Thunderbird. Tools, Add-Ins or manual methods, anything just to get me up and running. PS I’ve two pst files, one is the default main Outlook.pst and the second a secondary store I created in the folders of Outlokk called Store.pst, beside the none default storage location everything else is standard for Outlook and Thunderbird.

Hi! From some time now i have problem with GUI elements overlapping each other. It started with the window control buttons (that part, where you can close the window). Esthetics aside, it was not that big deal, so I just ignored it, but some time ago similar overlap appeared on address bar - so now I don't see what I'm writing. This is a big deal, now I can't really tell if I made a typo, I'm not able to correct it or I can't see if what I'm writing is mixed with original url, stuff like that.

I'm on Manjaro Linux and Firefox version is 127.0 (64 bits) I've tried to reinstall Firefox with different sources, like Flatpak for example, but the issues persists. Has anyone an idea how to fix this?

I move old emails to archive folders, by year, when I get around to it. Today decided to shift emails from Sent file back to 2020, and from Inbox for all of 2022 and for the first half of 2023. Archived each year's batch separately. In every case I got a "Thunderbird not responding", so eventually stopped it via Task Manager. When I restarted, all the highlighted emails had been moved properly. When I did it for the first half of 2023, all the emails appeared as expected in the 2023 Archive folder ... for a few seconds. Then they all disappeared, as did much of the content of the other annual archive folders. What do I do to recover all those emails?

I switched back to release from nightly because the themes support completely broke rendering of menus, buttons, etc on various (read: pretty much every single one, including this one) websites, making them difficult or impossible to use. I've tried a browser refresh to no effect.

unfortunately, it appears the feature has been rolled out to release now as well, as pictured below.

I've tried cycling through themes, setting custom colors and forcing it to never replace the website's specified colors etc, turning off acceleration... none of it works. this is an issue on my desktop, laptop, and tablet (surface pro x), basically every platform I use except mobile.

any ideas how to fix this? it's really annoying and I'd really like to not hop browsers again, I've been using firefox for a good long while now.

I'm on MacOS Monterey 12.7.5 with Thunderbird 115.12.2 (64-bit). I noticed two problems. First, the message Window cannot be moved to a different location. And second, the "ToolBar" with the "send" button is missing in the message window. I can't recall what I did to cause these two problems. Question: Is there a fix for my problem? Any help is appreciated. Thanks. Roger

I'm a writer. In keeping with the Law of Primacy, my first work is usually my best work (after a few tweaks). I recently had to write an email response to someone for the Darling Bride and me.

I waxed poetic and wrote an incredibly diplomatic response to a most unpleasant situation. After completing the entire message down to our signatures, I selected "File" and "Save" to make sure it was all saved in the Drafts folder. That way, I could open it on another device and read the draft to her.

Imagine my shock when I opened it, only to find that the draft stopped in the middle of a word - while I was correcting a typo - and didn't save anything after that! Frantic, I went back to the computer I used to write it, hoping the entire email was at least saved locally. Nope! The draft stopped in the middle of the message, even though I had saved the entire thing.

Perhaps this isn't high priority for a lot of users... but for those few of us, it's a critical, fatal flaw that has to be resolved. I can't even imagine that I did anything wrong: I saved the message before exiting; and opened to find half of it missing. I love the idea of Thunderbird and its privacy features, compared with the data-mining big names. But I can't afford to lose data! This was a personal response, thankfully, and not related to my work as a writer and author. However, I have to trust my email client with the data I save to it. Any hints to prevent this are greatly appreciated.

Latest update (127.0.2) erased all my data. Gone are my bookmarks, passwords, sign-in shortcuts, history, etc. and I'm trying not to panic. Most of my passwords are backed up but my bookmarks are gone as is all my sign-in shortcuts, etc.

I always try to keep updated and never have had a problem with anything other than having to relearn a few new things; but this is a first for me.

I am having trouble manually configuring an AOL email account (username@verizon.net). AOL's instructions say to manually configure the account. I tried to do that twice, once with IMAP and the other with POP.

Now, I have two email folders in Thunderbird that I cannot use. They are both empty because I get a message box that says "Login to server imap.aol.com with username@verizon.net failed." when I try to use them. When I use the same login credentials to login to the website mail.aol.com, they work.

I have to contact AOL as to why when I try to access the account with an email client (Thunderbird and Outlook) I'm getting password errors. In the meantime, how do I delete the two email folders created incorrectly in Thunderbird?

Thanks for your help.

Today I started getting repeated notifications, every 5 to 10 min or so, that my McAfee subscription has expired, my credit card has been rejected, and that my computer is infected. I do not use McAfee, either in Firefox or on my computer. I use the security suite that comes with Windows. I cannot stop these messages from appearing, and disabling notifications from McAfee in the messages does no good, the notifications just keep coming. HOW DO I MAKE THEM GO AWAY? They must be SPAM because I've never had a McAfee product on this machine, EVER. Thank you so much for the help, Dave Templeton

When I restart Mozilla Thunderbird, my S/MIME certificate preferences under Account Settings seem to break.

When I initially select a certificate, both the common name/certificate name and the certificate fingerprint appear in the interface (see Working Settings.png). However, after restarting Thunderbird, only the common name/certificate name appears in the interface, and I cannot use S/MIME to sign messages (see Broken Settings.png). When I attempt to do so, I receive the following error message:

Send Message Error Sending of the message failed. You specified that this message should be digitally signed, but the application either failed to find the signing certificate specified in your Mail & Newsgroup Account Settings, or the certificate has expired.

To be clear, Thunderbird has no problem finding and using the certificate right after I set it—the problem only appears when I restart Thunderbird and the appearance of the certificate in the settings changes. The certificate does not expire until April 2025, so this is not the issue. The issue also occurs with another account using a different certificate that is also unexpired.

I am using Thunderbird 115.12.2 (64-bit ESR) on MacOS with Apple Silicon.
