This is regarding TB 91.13.1 on Windows 11. I know with later versions of TB you can change a setting in Preferences > config editor to make the scrollbar wider. But this doesn't work with TB 91.13.1. In fact you have to add that preference, which I've done, along with several others. So far nothing makes any difference.

I've also added the text as mentioned here but it made no difference. https://support.mozilla.org/en-US/questions/1251403

Any suggestions would be appreciated, Thanks

In the past, when I had replies on emails I sent, they always came back as a separate email even though the subject line was the same (since it's a reply). This was with my old email server that was a POP3 setup. Anyway, when I created a POP3 Gmail account, now I noticed that the emails that are a reply get stacked like subdirectories in your filing system. That is, my original message is the first tab, then each subsequent reply is in a new tab so I could have 5 or more stacked tabs. The problem I have is that even though the latest reply might be the newest in date, when I'm in the main email menu showing all the emails I've received, this particular email is at the top of the list because the latest reply is the newest email, however the original date stamp is showing when I created that email rather than the date stamp of the newest reply.

Is there a way in the settings or something to have each reply as a separate email like I did with my old server? Or is this some kind of quirk because of the way Gmail does POP3? The reason I opted for POP3 is because I wanted the emails stored locally on my PC and I could delete all emails from the Gmail server rather than using the synchronizing method of IMAP where all my PCs would have the same emails (using POP3 I could have different emails stored on each PC as I could delete some on one PC while having them exist on another one). Thanks in advance for any suggestions you may offer!

I'm just getting set up with Thunderbird. I used to use Postbox, and imported my Postbox profile into Thunderbird, which overall worked great – it got all my local email folders, and brought in my Apple email account, and so forth. The only wrinkle I've noticed so far is that it also created an account named "server7.invalid" that I can't delete. If I go to Account Settings, for "server7.invalid" it states "The following is a special account. There are no identities associated with it." The only items underneath it are "Spam Settings" and "Disk Space". There is no red Delete button for it, the way there is for my two real (IMAP) email accounts. Viewed on the Mail tab, it appears to contain only "Trash" and "Outbox", and both of those are empty. This weird invalid account doesn't seem to be doing any harm, but of course it is ugly and I just want it to go away. Help?

Hello,

I have to add the Password every time I open Thunderbird because I removed the Password myself after I read this:

<<<< ThundaMike Mozilla Staff 7/28/25, 9:15 PM more options Sounds like you are almost there.

Building off what @david said above, try this:

In Thunderbird, go to Settings > Privacy & Security.

Scroll down to the Passwords section and click Saved Passwords….

Find your email account in the list and remove the saved password.

Restart Thunderbird.

When prompted, enter your new password. >>>

My doing this it removed the .twc password Log In totally in that Settings. I do not see the "my twc.com" in the settings of Tools, Privacy & Security, then Saved Passwords in the list, I only see the Hotmail account settings I have in Thunderbird. Removing it like ThundaMike wrote really removed all the TWC Password and Information.

Can someone help me restoring or re-enter my Mozilla Thunderbird info back into Tools, Privacy & Security, then Saved Passwords so I do not have to type in the Password every time I open Thunderbird.

Thank you so much for your time and efforts I truly appreciate it.

I've been doing this for (literally) decades.

If I initiate a search in all local folders, for example all messages to, from, cc or bcc a particular e-mail address, the results (as of about a week ago) now ONLY return messages found in Inbox or Trash. Also, after returning those results, the search indictor continues to 'spin' as if it's not done but still searching. None of the messages in my Sent folder appear in the results.

If I change my search to specifically look in the Sent folder, I get all the remaining messages I'm looking for. But it isn't helpful to have to perform two separate searches to get these two separate result sets.

I've tried quite a few things. Any ideas?

I'm not able to log into yahoo e-mail via Linux Firefox (145.0 (64-Bit)): The error message is "We were unable to log you in. Please try again from another device." I can log in with Chrome (Linux and Windows) and Firefox (Windows). My issue is to switch from POP3 to IMAP in Thunderbird. There the same error message occurs.

I am running Thunderbird version 128.11.0esr (64 bits) on Windows 10 Pro. I have defined, in Windows, the default program for .doc and .docx files to be LibreOffice Writer and this works fine when I click on such a file in Windows.

But when I got a docx attachment in a Thunderbird email, and clicked on it, nothing happened. When I right-click on it, it just offers to open (not to select which program to open it with). I have to save the file locally, and click on it in Windows in order to open it.

This is very frustrating, all the more so that it used to work. I tried adding the two following lines to the prefs.js file, to no avail - no change:

user_pref("network.mime-handler.external.application/vnd.openxmlformats-officedocument.wordprocessingml.document", "D:\\Program Files\\LibreOffice\\program\\swriter.exe"); user_pref("network.mime-handler.external.application/vnd.openxmlformats-officedocument.wordprocessingml.document.useSystemDefault", false);

Any suggestions? Thanks!

I am getting the following error message in Thunderbird. Unable to download email to mailbox. Please make sure that the file system has write permissions and that there is enough disk space to copy the mailbox. Write permissions are available and there are 735 GB free.

Three days ago my email stopped displaying the contents normally. This is an example of what is displayed:

View in Browser <https://m251k6d7.r.us-west-2.awstrack.me/L0/https: %2F%2Fnotifications.spectrum.net%2Fv2%2F7653dbh8-914b-49e3- be46-3485432704ac-6fbcc229-1aff-472f-9d60-30d142f28bc0/1/0101019a92a6f846-7a7a6a44-ed3f-4919-9e07-7fb9f874272d-000000/FQOZxe1pRaghhBS9ePfM5pAm3RI=453> Spectrum Community Solutions

the instructions are in blue. Thanks for any help.

I have been using Thunderbird Mail for many years and have been satisfied with it. I followed the recommendation to upgrade to version 145. Then disaster struck: the previous version was completely deleted, including all email accounts and address books. How is that possible?

In Thunderbird's Settings under "Language & fonts, Choose the languages used to display menus, messages, and notifications from Thunderbird" I have selected Danish and English. Now I would like to remove English, because my folder pane is displayed in English, even though I have selected Danish as the first language (I am from Denmark). But I cannot remove English in Settings, only move Danish or English up or down. I cannot click on the Remove check mark, neither for Danish nor English. Does anyone know why?

I have an email account with BlueHost, which also hosts my web domain. A couple weeks ago I stopped receiving emails and contacted BlueHost tech support. The agent had no clue why I wasn't receiving email. She said "Can you please click on acocunt actions and remove the account and re-addd it. [sic]" I did that, and I was again able to receive emails. But then all my old emails -- sent and received -- had disappeared. BlueHost was able to restore my Inbox emails back to May 19, but was not able to recover any Sent emails. I have a backup of my Thunderbird directory from April, but would like to recover all of my old emails, which apparently still exist because my current Thunderbird Profiles directory contains files corresponding to deleted email folders. For example, my Inbox had a subfolder -- call it ABC -- that was deleted and is no longer visible in my Inbox, but I can find files ABC (no extension) and ABC.msf in my Inbox.sbd folder. My Sent.sbd folder also contains files ABC and ABC.msf. These folders are in C:\Users\aaa\AppData\Roaming\Thunderbird\Profiles\aaa.default\Mail\mail.aaa.com (with "aaa" representing my personal identifiers). mail.aaa.com contains files Inbox, Inbox.msf, Sent, and Sent.msf, which seem to contain my old emails. (Inbox is 132,151 KB and Sent is 289,829 KB, and the file dates are from a couple weeks ago, when I removed and re-added the email account.)

Is there a way that I can recover the old emails?

I am trying to install an add-on to enable the transfer of large email attachments but, having tried to install a "selected" Filelink add-on, I receive a message that it cannot be installed as it is not validated by Mozilla. Please advise which add-on is accepted. Thank you.

I want each email I receive on a separate line in my inbox. Currently emails from the same address are being kept in the same location in the inbox. I have tried to uncheck threading but this does not help. This behavior results in my not seeing a new email from the same address as the previous ones which are still in my inbox.

I am trying to install Thunderbird on a computer with windows 10 pro but install gives a message cannot install require a minimum of windows 10 but I do have that. what can I do please. Regards Neil.

Why is this folder SO LARGE !!! C:\Users\xxxx\AppData\Roaming\Thunderbird\Profiles\6v2ccsvd.default-release\ImapMail

On my PC, it is over 3.5GB !

How can I minimize it !
