Forum der Gemeinschaft Thunderbird

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 want to send photographs from my Android phone to the "pictures" section of the Thunderbird e-mail program. The photos are going into that section but I can't see the picture itself as they just show wording as extensions. How do I get the actual picture to show up? How do I put my desired description of each of the "pictures" on the list along with the extension wording?

After updating Thunderbird to version 148.0 (64-bit), my system crashed. I rebooted and tried updating again. I am now sending and receiving emails normally from only one of my three AOL email addresses. I have attempted to reconfigure the settings on the other two manually, to no avail. Can the settings be corrected automatically? Please direct me to helpful guidelines that I could follow. Thank you.

hello, i cannot seem to find a solution online, hopefully someone here can help.

i often receive emails with images attached, and most of the time people don't resize the image. so you can imagine over time this all adds up. i dont always need to keep a 6mb image versions. i would love if there is a way to resize the email image attachment, to at least still have a smaller copy for refence, but not end up with a huge email account (local/pop3)

preferably a one click solution, or even a routine i can run on the file system, etc.

thanks

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 have a Windows 11 operating system. I tried browsing/uploading a couple email messages describing providing more information but wasn't successful. Can you help me ?

I am experiencing a persistent "ghosting" issue where deleted messages reappear in the "All Mail" folder. Environment: Mac Mini M2, macOS 15.2, Thunderbird 140.7ESR. Configuration: Gmail IMAP with "Auto-Expunge OFF" and "Immediately delete the message forever" selected in Gmail Web settings. Behavior: Using Shift+Delete or emptying the Trash in Thunderbird appears to work locally, but upon restart/re-index, messages return to the "All Mail" folder. Even after 2+ days, a search on the Gmail web interface still reveals the "deleted" items. Issue: The EXPUNGE command does not seem to be successfully committing to the Gmail server in this specific version build. Note that the TB has gone through some major rebuilds from 140.6 back to 128 ESR to 140.7ESR in the period from early Jan till 2 weeks ago. Very recently, TB became once again very slow on a start up, including after rebuilding of the large All Mail file of 66K items. A month ago, I added Satechi with 2TB drive split evenly between Time Machine and Other data. Significant oscillations took place in free memory on the MacHD between 60BG and 10 GB, currently at 58GB. Safari is my browser.

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 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.

Four accounts: Rogers Yahoo, Office365, GMX, and a second Yahoo account

When Thunderbird recently asked to access to my provider's server, I gave my Rogers Yahoo account and password; everything looked fine. But when I tried to use my second Yahoo email account, all the folders contained the same data as the Rogers Yahoo account, even though the email addresses were different; my original emails were gone from the Inbox and other folders.

So I began to follow the instructions in Mozilla's page "OAuth2 Authentication for Yahoo, AOL and ATT". 1) with Config Editor, changed "mailnews.oauth.usePrivateBrowser" to TRUE 2) checked for "Accept cookies from sites" in Privacy & Security settings 3) checked authentication settings: All Outgoing servers were set to "OAuth2", as well as Yahoo and Office365 incoming servers. The GMX incoming server was set at "Normal Password" with no option for "OAuth2". 4) I am in Canada and do not use VPN. 5) Finally, I deleted the second Yahoo account (tc2002ca) and all its data from Thunderbird. I logged into Yahoo! Mail online to make sure I had the correct password. I then added tc2002ca as a new account using manual configuration. I entered all the settings to match the Rogers Yahoo account, except (of course) the password which was associated with the tc2002ca account. The result: same as before - all the folders of this account were identical to the Rogers Yahoo account.

To summarize, all the settings in the two Yahoo accounts were the same (imap.mail.yahoo.com and smtp.mail.yahoo.com) except the passwords. When I "tested connection to server" in each case it came back "Successful". Please help me get back to having two Yahoo accounts in Thunderbird, as I have had for years. By the way, I have had no problem using SeaMonkey in a similar way. Thanks!

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!

Since the firefox upgrade of March 4, 2026, I have lost all of my old emails in my inbox. These are important items I need to work on before I complete and file away. I need to gain access to them ASAP. Thank you.

Hi!

I can't get messages from my Thunderbird account. When I click "Get messages" nothing happens and it usually says "Done" on the bottom left corner. I have to use my domain's webmail account to get my e-mail and it only allows me to read it and delete junk.

I really would love to have my Thunderbird account working again as soon as possible.

Thanks so much, Nancy Pedersen

I subscribe to a number of RSS feeds in TB. This works well nearly all of the time but sometimes I find that TB has paused updates. I never want it to do this.

Why does it happen and is there a way to stop it doing it?

bold text I have tried restoring my system to a previous date. I did receive those Emails. Today, I've not received my Email messages. I have tried you help resources and have been able to get Thunderbird to run as before. I would appreciate any assistance that you could give a seventy-six year old user.

When I search for a name in Thunderbird mail e.g Lennart, nothing from 2026 comes up, only older mails from 2025-12-31 and backwards. if I search on his e-mailadress, e.g l.name@ppost.se it finds avery mail. What is wrong?

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!
