I have "Open previous windows and tabs" and "Open Firefox automatically when your computer starts up" boxes checked in my settings.

Firefox is not opening automatically and my previous tabs are not showing up.

Thanks

I have over 200 email accounts in Thunderbird, and I am getting constant pop-up error messages that say: "Не удалось открыть индексный файл для 'Входящие на [email]'. Возможно, произошла ошибка на диске или полный путь превышает допустимую длину."

I don't need help fixing the emails themselves, but I need to permanently disable these pop-up alert windows because I will soon have over 2000 accounts and I don't want 2000 errors popping up.

I am using the latest version of Thunderbird. I have tried looking for "about:config" or the "Navigation Toolbar" to change the settings to "false", but my interface is heavily customized and I cannot find the menu or the address bar. I need a step-by-step guide on how to disable these error alerts, preferably using the Windows Registry or a configuration file if the menu is hidden.

Years ago when I was using Thunderbird there was "fix" for the Advance to next message pop-up, which appears when you press N or P to move to the next/previous message, and that message is on another account. If I remember correctly I think the fix was going into the "debug list" where you could change individual settings if you knew the name of the setting, and set it to off.

Anyway I couldn't find that list at all in the current version (probably a good thing). Is there a setting somewhere or fix where I can turn off this popup?

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;

}

I have Thunderbird 153.2.0esr which runs 2 Email filter (on Inbox and on Outbox)

These filters worked for years.

Suddenly, about at the end of July 2026, the stopped working.

I suspect that one of the latest release of Thunderbird make them stop working.

Is it possible? Any suggest?

Also the filter log registry is empty.

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.

After the lake Ontario disaster by the Mad King, I do not want to use Google or Apple and anything I don’t have to. How do I make Firefox and Mozilla my default settings on my mobile as I’ve already done it on my computer.

On September 5, Thunderbird updated to 155.0 (20260828141248) (on Windows 11 10.0.26200). I use IMAP.

Since then, when I try to delete a message, I get an error: The current operation on ‘Inbox’ did not succeed. The mail server for account <email address> responded [TRYCREATE] Mailbox doesn’t exist: INBOX/Trash (0.001 + 0.000 secs)

But in Settings, "When I delete a message: Move it to this folder: Trash" is set. Not Inbox/Trash or INBOX.Trash, which also exist, but Trash at the same level as Inbox. I logged into webmail for this account, and there's definitely a folder for Trash. All deleted messages prior to the update are still there. If I delete a message in web mail, it is moved to the Trash folder.

The same is true of the Sent folder. In Settings, "When sending messages, automatically: Place a copy in: "Sent" Folder on: <account name>."

It looks to me like Thunderbird is doing something different from what the Settings say, and definitely something different than what it did before the update.

Suggestions?

With my new monitor, I've run into a problem with the space available for the actual message. On the attached image, I'd like to completely delete the stuff circled in red. I don't use it and it takes up a lot of space. I've resized the first two columns as much as I can, but I still can't see any of my full messages unless I open them in a new window or tab, which is inconvenient.

Thanks for any help you can give me!

I'm aware (e.g. https://support.mozilla.org/questions/1277401) of how to toggle whether the message window stays open (opening the next message) when an email is moved or deleted. But I would dearly love for it to happen only sometimes.

Specifically, when a new message comes in, I want to read it, usually move or delete it, then read the next new message, if there is one. But if the next message is an old one, I don't want to keep having it shown to me. I keep my inbox fairly tidy, but I'm getting sick of seeing that message from a year ago that doesn't have a better place to be.

So, after moving or deleting a message, if there is an adjacent unread message, keep the window open. Otherwise, close it.

If there's an unread message somewhere else in the folder, don't jump to that one. Trust that I've left it unread for a good reason, and don't want to now constantly get shown it, and also have to remember to mark is as unread again.

If it's easier to look for other unread emails based on dates, a few days (enough to span a long weekend, for example) would probably be enough, a week at the most. Or make that number user-configurable.

I used to be able to set message filters to play a sound of my choosing after a message was filtered into a folder (a chime so i know when mail from a client arrives). For a while it was not an option, so I used various extensions that eventually were no longer supported (ToneQuilla, Mailbox Alert, FiltaQuilla, Soundmail). I suspect that the last one may have corrupted my Thunderbird and caused my recent issues, so I removed it (and now I have no extensions installed). Sound Mail is the only extension I can find that plays a sound for filtered mail only.

Meanwhile, the "Play Sound" option has appeared again in v155.0.1, but with no choice of sound file, and nothing plays. It's not a sound issue; other sounds play in other programs, and the normal new mail sound plays when I enable it (but I don't want sound notifications for all mail, just client mail).

Any solutions?

On early version of Thunderbird on Windows 7 I see the mesage window below the header window. I would like to see the same on the later version on Windows 10 and 11. So far I've been unable to find a control to do that.

Good afternoon

I have been struggling to find some messages specific to specific dates and spend an awful amount of time tryomh yo access the correct one.

The solution proposed is a bit unclear to me, as it refers to "future folders". I need to unthread all my messages. Is this possible?

Thanks

PS The only version number i could find was for Firefox. There does not seem to be one for Thunderbird.

Enclosed are jpg copies of the current sets of filters failures in my TB email program.

TB Error0 shows the 6 emails that have arrived and are placed in the INBOX. However, each of these has a corresponding filter set up to move them upon arrival to a separate subject email mailbox.

Note: If I highlight the INBOX and then go to Tools > Run Filters On Folder ... all of these INBOX email messages will be correctly filtered and moved to their respective email mailbox, BUT each of them is shown as having been "read" and unless you pay close attention, you may not know where these INBOX emails were sent.

I am also enclosing TB Error1 & 2 that show the last couple of days message filtering errors.

I can find nothing wrong with how each of these filters are set up, yet they seem to consistently fail to operate when new emails arrive.

Note one of them is for incoming emails from ... schiffsovereign.com. I have edited this filter repeatedly, even deleted it and re-input the information. Yet the filter never takes hold and does what it is designed to do. I am enclosing a jpg of that specific filter as TB Error3

I am looking for suggestions on how to fix this problem.

Thank you and best wishes,
