I have been unable to add Yahoo as the default search engine. No matter what address I type in, it consistently comes up with "Could not add OpenSearch Provider for".

In Thunderbird why do I (still) get repeated tabs for the same (INBOX) folder?

Many previous answers go back to 2022 with answers that do not work now (like find an add-on in Tools for deleting duplicates).

A few times I have missed messages that have have been inadvertently placed in the Accounts Spam Folder. Is it possible to to indicate that the Spam Folder has contents in the same way contents are indicated in other Account Folders?

Thunderbird has been working well, but all of a sudden it stopped sending my emails from aol accounts. I have tried many internet solutions and nothing is working.

My Thunderbird Account was updated by TB on 2 September. Since then all of my new emails go to Trash. Although I've tried the various responses to such questions, I've been unable to change the problem and get my new emails to come into my Inbox. I'd very much like your assistance please. Thank you.

These are some things I have explored:

   • It is happening whether I look at emails in Thunderbird or through Gmail on Google Chrome
   • Even if I clickndrag them from deleted to inbox they fall back into deleted.
   • I’ve tried gmail/settings/all settings/filters and there aren’t any
   • I’ve tried gmail/settings/all settings/forwarding and there aren’t any
   • If I access Gmail via Microsoft Edge, the emails stay in Inbox
   • I’ve looked at various things in Thunderbird and unticked something in ‘When New emails arrive’ because I thought that might work.  

It started happening about a week ago.

This problem happened after the September update. No changes to any message filters. I am not the only one having this problem. What changed in the update that could have caused this problem? I have had to delete the problem account from Thunderbird because every time I move the messages back to the Inbox in Outlook, Thunderbird would move them back to Delete.

Hey everyone

I need to remove the line that is added when you reply to emails. It adds added steps when cutting and pasting when I quoting emails when replying.

I have multiple profiles with multiple emails in each profile.

I found a thread here dated 2016 that instructed to add this to the css file.

I didn't have en excisting css file I could fine so I created a folder. >chrome > and put a userContent.css file within that.

This is code.

blockquote[type=cite] {

  padding-bottom: 0 !important;
  padding-top: 0 !important;
  padding-left: 0 !important;
  border-left: none !important;
  border-right: none !important;

}

Almost anything I try to do with Thunderbird, even replying to emails requesting advice, I come up with errors, such as:

Sorry, you have been blocked

You are unable to access thunderbird.net

upstream request timeout

upstream connect error or disconnect/reset before headers. reset reason: connection termination

Whilst exploring settings I managed to create a second duplicate "stgilb@optusnet.com.au" account/profile, ie two inboxes,drafts,sent,spam & trash. In trying to eliminate the duplicate I succeeded in creating a triplicate. How do I return to a single account/profile?

A solution would be greatly appreciated.

An example of an added space would be:

director-concertband@oceanside- music.ca

Note that after the second dash in my address above, in the saved HTML Sig Card, the space is added. When I remove the space and re-save the Sig card, the space still returns.

Also note that this happens ONLY in the signature card. The addressing in the email itself is correct. Any help you can offer would be appreciated.

I try to set up gmail but get the message "Error Creating Account Incoming server already exists."

I have my main Spectrum email set up fine but I have no idea where to even begin with setting up gmail since I get the message above.

I have three separate Yahoo email accounts. I set up Thunderbird to link to each Yahoo email account separately. It worked fine for a year or more. On 5/25/26 one of the three Thunderbird email accounts stopped downloading emails from Yahoo. I could see at the bottom bar Thunderbird indicating that is was downloading 1 of XX emails, but never actually downloads them. There is no error message. I checked the Yahoo email account to verify the number of emails I am missing from Thunderbird and the number is correct. I can see the emails in Yahoo. I'm the only person using Thunderbird, so no changes have been made to previous settings for retrieval. I confirmed Security and server settings for Thunderbird in and out going emails, and Yahoo are correct. I tested the connection in Thunderbird, and the connection is successful. I tried to send an email from the Thunderbird account having issues, and the email was sent and received by the recipient. The recipient replied, and Yahoo received the email, but failed to download it to Thunderbird...along with all the other emails since 5/25/26. I unlinked the account and reestablished the link between Yahoo and Thunderbird, and still not fixed. I tried restarting the computer, with no change. I tried to send an email from Thunderbird to one of the other Thunderbird emails and it was sent and received. I made changes to Thunderbird to force the download of emails, and it still wouldn't do it. I turned off my antivirus, closed Thunderbird, and restarted it, and that didn't change anything. The capacity of emails on the email in question only has 739 emails, so it's not over the limit and I have plenty of storage capacity. Thunderbird is set to save emails, Cookies and cache were cleared, no change. I ran the folder repair feature in Thunderbird, but there was no change. I compared all the settings between the other Thunderbird emails that are working against the one that isn't, and they are all the same. There was a suggestion to close out of Thunderbird and delete the "Global-message-db.sqite" file from the Thunderbird profile in case it was corrupted, and it would recreate this file when Thunderbird was restarted. The file was recreated, but it didn't fix the problem. There was mention that a suspicious email in Yahoo might be blocked by Thunderbird, so I placed various emails in the spam folder, and it didn't work. I did find one email in the Yahoo spam folder that was dated before 5/25/26 and moved it to the Yahoo inbox. Lo and behold, that one email downloaded to Thunderbird. So there is something within Thunderbird preventing emails from downloading after 5/25/26. I've read many people complain about similar download failures with no solid fix. Someone mentioned it fixed itself on a day, but then stopped again days later. Someone else mentioned Yahoo changed its password protocol to transfer emails, but that doesn't make sense since the other two are still downloading based on the "old" password protocol. I'm at wits' end. Thanks for reading all of this. I hope someone has a solution.

Since the launch of Thunderbird (Android), I have been using it. Recently I changed the email account password and now want to update it in Thunderbird. I can’t find an option in the app to update the password, and the app is not prompting me to enter the new password.
