Von der Erstinstallation war ich gewohnt, dass von oben nach unten die Darstellung der Ordner wie folgt war: Posteingang / Entwurf / Gesendet / Archiv / Spam / Papierkorb / Local Folders /Postausgang / Unbekannt Nach der neuen Installation, die erforderlich war (Rechnerneuinstallation) ergab sich folgendes Bild von oben... Lokale Ordner / Papierkorb / Local Folders und dann alle meine selbst erstellten Ordner am Ende dieser Aufstellung kam die Zeile mit meiner web-Adresse xxxx.xx@web.de dann Posteingang usw. siehe oben aufgeführt Damit liegt der Posteingang am Ende meiner Ordner Auflistung und das ist über den unteren Monitorausschnitt hinaus, diese Situation ist für mich untragbar und deshalb werde ich wohl auf ein anderes e-mail Verwaltungsmedium umsteigen müssen. Eine Kopiermöglichkeit um die Ersteinstellung zu erreichen war kläglich gescheitert und jetzt ist das Durcheinander noch größer beste Grüße B. Bein

bold text Hi, I have Yahoo mail and Thunderbird. I want to use TB as my main mail but still keep my Yahoo account as the data is stored by yahoo and I suspect I will loose my history if I cancel..

I leave my email and a couple of other tabs open when I shut down. I cannot make TB appear as a tab, it always opens full page.

Any ideas?

I would like to know how I can control the timing of compacting the mailboxes under Linux and Windows. The reason why I ask is that every time compacting needs to be done, the prompt to do so comes up as soon as the Thunderbird interface finishes loading but before all of the mailboxes are finished updating,which can take several minutes. If I accept the compacting, it inevitably returns an error that it could not run because the mailboxes are still updating. Or I can cancel until I go through this the next time.

It would seem like a simple matter to either give the user a way to delay the compacting process, or have Thunderbird not initiate it until it is safe to do so to begin with.

I have tried to research this but have not found any answers.

Hello community,

I'm trying to find a solution to probably a basic problem and one that been discussed a lot. I use Thunderbird on a Mac and want to remove the arrow indicator from the Subject field (screen shot attached). I've tried several different recommendations, but none work.

Any advice?

Thunderbird in the past showed a red number above the dock icon telling me I had so many new emails. The newest version I now have does not do that and I cannot find a setting for that. Anyone know how to get the number back????

I tried the Toolbar fixes in this forum and got the menu to show up, thank you. (Any menu in Compose mode had disappeared. Actually, both Firefox and Thunderbird icons on desktop and Taskbar had disappeared as well, and I had to reinstate shortcuts. This may or may not be pertinent.)

But when I try to add "Send" to the menu, using customize, the "Send" icon is nowhere to be found as an option, so I cannot add it to the Toolbar in Composition mode. "Send" is grayed out in all bold textmenus. If I use Ctrl-Enter, message does get sent. Using Windows 10, still. Perhaps this is an upgrade issue?

I am using Thunderbird 140.8.0esr (64-bit) on Kubuntu 25.10 multi-monitor configuration. New install, very little customization.

Thunderbird will not retain the window size or position for the main window or messages. I have have tried deleting both the xulstore.json and session.json files (one at a time and both). When I delete the xulstore.json file and restart Thurderbird, it starts maximized. When I set the position manually e.g. to use about 90% of the screen for the main window and about half the width and about 90% of height for a message window and then close Thurderbird I can see the new window size vales written into xulstore.json e.g 2493 x 1362 and 1501 x 1317 "messengerWindow":{"sizemode":"normal","screenX":"0","screenY":"0","width":"2493","height":"1362"} "messengerWindow":{"sizemode":"normal","screenX":"0","screenY":"0","width":"1501","height":"1317"}

When I close and restart thunderbird it reverts to opening in the center of the primary monitor at a smaller size than when I closed it. The values in xulstore.json have changed to 960 x 540 "messengerWindow":{"sizemode":"normal","screenX":"0","screenY":"0","width":"960","height":"540"} "messengerWindow":{"sizemode":"normal","screenX":"0","screenY":"0","width":"960","height":"540"}

I found a similar recent question if this helps with a possible solution: https://support.mozilla.org/en-US/questions/1527783 but I cannot locate the referenced userChrome.css file to see if there might be something similar to try.

I am also using a multi-monitor setup. If I move the Thunderbird window to the second screen and close it, it always re-opens on the primary display at the 940x540 size. Thanks!

Hello, Firefox. So I have this feature whenever I type. When I type my first letter, it is capital, and whenever I add an comma to my sentence and hit the space key, it adds an period. I don't remember enabling that feature, and I want to disable that feature. Is there any way if I can disable that feature? Thanks in advance!

Thunderbird 148.0 moved trash folder from top group in folders pane to alphabetical order in lower group. Reopening Thunbird didn't help. How to get it back into place? Thanks!

I configured a series of "Filters" on my account inbox (imap), that move certain messages into specific (sub)folders. E.g. "To: certain@address.de" , filter applied when fetching messages "before junk detection" (German UI: "Filter anwenden bei: Nachrichtenabruf").

The filter seems to just silently fail and do nothing, since I also use my Android K9-Thunderbird app (imap) on the go.

How can I get my Thunderbird desktop filter to work again, even when imap fetching/accessing new messages with the phone?

Thank you for your informed insights

I am using Debian Trixie with firefox 148 and I reported that the refresh option was missing from Firefox, https://support.mozilla.org/en-US/questions/1569549. I then noticed another workstation with the same version of FF that did not have the "refresh firefox" option.

It appears firefox has been changed. Some of the items have been changed including the profiles option to add color on creation.

How can the parameters of FF be changed ? See enclosed menu under help, "more trouble shooting information", you will see "refresh firefox" is missing from the top right.

Mozilla currently allows a user to select an AI Chatbot to use in the updated sidebar. The choices are limited to Anthropic Claude, ChatGPT, Google Gemini, Le Chat Mistral and Microsoft Copilot. When will Mozilla add Grok to this list of choices?

I have reset Firefox as default browser on my Windows 11 PC a hundred times in the past few months. Today, I could not reset it at all -- I click the default button in Windows 11 and as soon as I close that settings window, it disconnects. I've run out of things to try to fix this. I think it MIGHT be related to Norton 360, because I first notice this problem when I opened Norton.

I received an IMAP email as normal, from an email address that I often write with. What I always do: the IMAP inbox is forwarded move on arrival to the local inbox. It had an attachment, and I downloaded that as normal. Then after 5 minutes I wanted to start work on the reply to the message in the local inbox and ... the message was gone. Nowhere to be found. Not in the IMAP inbox (of course), not in junk, not in trash. I looked in the on-line IMAP account, and there the message was present as normal.

Then I searched for the email and there it shows: in "Inbox". And I see one strange thing that I never saw: column Message threads says: "This subthread is ignored". So that is the problem. Probably I hit accidentally some key (k ?) and this caused the "kill".

Now how to un-ignore it? There is this Help page: https://support.mozilla.org/en-US/kb/ignore-threads and it says: "To un-ignore a thread that has been marked ignored, select a message in the thread, right-click on it and again select Ignore Thread. ". But right-clicking the email (in the search results) shows NO such option.

What can I do? Thanks!

I frequently get messages that are all messed up due to fonts. Lines overlap, symbols instead of characters, etc. Is there some way to have Thunderbird use some other substitute font than this? Thunderbird 140.8.0esr (64-bit) on Linux Mint Cinnamon

Very little to do with accounts, but none of the selectable topics cover 'user Interface'.

Used to be able to open different accounts in different windows. Can't remember how, but it was obvious. Once new window is created, each time Thunderbird is started it re-creates them. I accidentally closed one and can find no way to re-open it. I use three email accounts each needing a different mindset, so keeping them in different windows helps. Also one has a screendepth full of folders and so is easier to handle in its own window. (The others are still there but only take up one line each when collapsed.
