Thunderbird Community Forum

Just installed Thunderbird and can receive emails but not send them. Error message says the message could not be sent because connection to outgoing server SMTP mail.twc.com timed out.

My settings seem correct and I can send and receive emails through the companies website but not with Thunderbird. Thanks

Thunderbird had never crashed before, but lately, after the last 2 Windows 10 updates within the last 2 weeks, it crashes. It's at 128.5.2esr, the next-to-last update.

It always crashes when I choose "About" and it starts downloading the update. It appears that it doesn't get the 1st byte before crashing. It will still say 0 bytes when it crashes.

It also crashes if I leave it running and the screen goes through the screen saver mode and turns black. Twice it crashed while I was using it.

I thought it might have something to do with the fact that I had 4,000 emails in my Inbox (is there a limit?), so I deleted many and moved many to folders. I now have just under 1,000 in my Inbox.

I also tried restarting in Troubleshoot Mode and updating, but it still crashed at 0 bytes downloaded.

Is there a way to manually download the update and apply it? I can't find it on the website.

The next thing I know to do is reinstall. Is there anything I can try before doing that? Would you suggest uninstall first or reinstall over what's here?

I upgraded Quickbooks desktop to 2024 version and no I no longer have Thunderbird. I checked in control panel and it shows up. When I try and open the program I receive a message to reboot my computer. After rebooting I still don't have Thunderbird. I try opening again and get the same message to reboot. Should I uninstall and then reinstall it? Wont I lose all my email accounts?

This has been going on for many builds now, for Thunderbird Nightly versions 136 and 137 and now Beta version 136.

The notification sound will play if the program is fully open but not if it's minimized.

Really annoying. It worked as it should in previous build versions....

Hi. I renamed a folder and stupidly used a special character (I think that's what caused the problem). The folder is now empty. Seeing an old reply on the forum, I looked in the file list and see that the data seems to still be there but I don't know how to get it back. I've added an image of the directory. It was called .HOLD and I changed it to .Check Here -> HOLD. I changed it back to .HOLD to see if that would help but it didn't. I closed and restarted Thunderbird and that didn't help either.

Thank you for any help.

New system, new install of Thunderbird. I get the following error :

[GFX1-]: RenderCompositorSWGL failed mapping default framebuffer, no dt [GFX1-]: glxtest: DRM render node not clearly detectable. Falling back to using the only one that was found.

Thunderbird seems to work okay, but this is annoying.

I wish to send an encrypted email. I have imported and accepted the recipient's public key.

When I compose an email to this recipient, the "encrypt" button is disabled.

Also, the security button mentioned in this article is not present on the compose toolbar, or anywhere for that matter https://support.mozilla.org/en-US/kb/openpgp-thunderbird-howto-and-faq#w_how-do-i-send-an-encrypted-or-digitally-signed-email

Windows 11.

Any idea how to fix this?

I use an adblocker that keeps YouTube from displaying advertisements before displaying a video. It works fine. However, when a friend sends me an email with a link to a YouTube video the video always begins with an advertisement when I click on the link. If I copy the link as text and paste it into my browser (Firefox) the ad doesn't appear when I start watching the video.

I'd like to be able to avoid watching the ads. Is there something I can set in Thunderbird to allow the adblocker to work before YouTube starts to display a video?

Every time I open Thunderbird, I am being prompted to enter my icloud ID and password for the icloud calendar sync function. I enter the credentials and everything seems OK - until I close Thunderbird and then open it again. I am using an app specific password and my correct ID. What is wrong?

Previously while looking for a specific email by text in the subject line, the results would display the emails in the same frame where all emails were. No need to open another window or tab.

I do this to find attachments. I would find the email, be able to open it and then print the attached PDF document. I can no longer dot this.

It started when looking for an email that had become part of a "Thread". I really do NO like threads. I changed a setting to NOT use threads but must have changed something else. I could not find it

I found my problem. I did NOT have "subject" checked in the search criteria.

By the way, I still do NOT like "threads".

Accounts using Exchange Web Services are possible as an experimental feature in version 128. After enabling experimental features in the config editor, the option of Exchange Web Services appears when creating a new account.

I am not able to create an account. The first time that I click on "Done" after entering my account information and selecting "Exchange Web Services" as the protocol, the "Done" button is dimmed and nothing more happens.

If I click on"Cancel" and try again, a message says that the incoming server is already in use with another account. That is true.

Questions:

1. What is preventing me from setting up the account the first time that I try? Is it the shared incoming server, even though no message is given, or something else?
2. How reliable is the support for Exchange Web Services? It is experimental, but it could still be more good or more bad.
3. What is the best way to avoid having the new account and the existing account use the same incoming server? If the new account works well, it will replace the existing one. I deleted the old account and tried setting up the new account in its place, but still received the message about the same incoming server being used. What is making Thunderbird think that the same incoming server is being used after the old account was deleted? Is there something that I can do with a new profile that would help me get through these obstacles?

Many thanks for any help.

Having posted that I was unable to get an email account working on Thunderbird. In frustration I removed it and reinstalled. Now its seems when I try to open it, it says the app cannot be found. It seems to have got worse and worse as the day goes on

So now even when downloading I cant open it. All this whilst trying to negotiate Windows 11 for the first time. I cant find the Thunderbird profile on the PC either.... so much easier with W10

Any ideas?

When I log in to Thunderbird, performance is fine for a little while, and then suddenly and for no apparent reason it slows down so that it is unuseable (5-10 seconds to complete one click command). The task manager tells me that it is occupying c10% of CPU. After a while it stops being slow and I can work for another few minutes, and then it slows down again. It is unuseable. I am using Thunderbird 128.6esr (32 bit) with Windows 10.

All help gratefully received!

Whenever I search for a word in emails that I have in my mailboxes, Thunderbird displays the underlying HTML code of emails, rather than their formatted form. When I click on one of these, it displays correctly, i.e., formatted. This is very annoying, as the HTML can be quite long. See attachment of beginning of result for searching the word "libération".

I'm using latest Thunderbird version set with IMAP on W10. It works fine and the PC is on 24x7. Every now and then Thunderbird stops sending Mail claiming it cannot contact the SMTP Server but the Server is correct and it works fine. I have to reboot the PC in order to make it capable of sending Mails again. CPU, RAM, SSD and Net values are almost Idle. I'd like to identify what causes this issue. I've checked the Windows Application Log but there's anything that helps. Where can I start troubleshooting from? Thanks.
