For quite some time now, I have been getting a Quota Warning that I was nearing my 10.0 GB limit. Now the program shows that the 10.0 GB limit has been reached, I eliminated a large amount of my emails recently but that action did not make any difference in the Quota Warnings. I was still able to send and receive mail, so I put the Quota Warning into a filter that would automatically send it to the trash folder. Now, after apparently reaching the full 10.0 GB limit, I have lost a vast number of emails I had in various folders. So, I downloaded and installed your newest version and hoped that the problem was solved. I still got the red percentage bar in the lower right hand corner of the pane, indicating the 10.0 GB limit had been reached. So, I went into my Inbox and deleted about 150 messages in there. Now the red warning is not showing in the lower right corner. Was my deletion of the messages in my Inbox effective in affecting this change? Why were my other archived and stored email messages deleted? The fact that they are gone did not, apparently have any bearing on the 10.0 GB limitation. Only the volume of messages in the Inbox has any bearing upon the limitation. Is the IMAP selection rather than the POP3 selection in the settings the place where the 10.0 GB limitation can be eliminated? It would be nice to know the answers to these questions along with a little explanation about why the limitation warning is so vague. Losing mail that you have tried to segregate and preserve is disturbing. Just trying to be nice. I hope you will be too.

I am trying to import a ics file into thunderbird. If I specify a local calendar as the destination calendar, the import works. However, if I specify a caldav-connected calendar as the destination, the import starts but never completes, and I always see an import status of 0%. I have tried importing into calendars from different caldav providers, but in all cases, the import fails. I would greatly appreciate your feedback. For me, this import is a convenient way to semi-automatically populate a web calendar.

Please is it possible to set a Global column order in emails? I would like the order of columns to be- attachment -present, Received -date, From-email address, Subject. And this to be for all email accounts I have setup (about 10) and all their children sub folders. So that is a lot of folders! I can see you can set it for one email address. And note certain updates have reset the order. The most important is the date at the left.

Thunderbird will not open. Instead a page appears asking me to open a new account, with an octopus icon and the heading FREEDOM. Is this a scam? I am desperate, I constantly need access to my sent emails and address list. What is happening? I do not understand the terminology on the page about crashes.

Have always set up accounts so they download all messages to hard drive.

Since 3/27/25, it is as if it never officially logs the downloads as downloaded, so it downloads each day as if it hasn't been done since 3/27/25, marking all of the messages since then as new.

File is very large so want to try fixing without deleting entire file.

Tried the 'repair this folder' but that didn't work.

Having trouble identifying the exact folder on the hard drive to delete since there are several different accounts in the Thunderbird setup.

Why for about the last week has Thunderbird been crashing when drafting a message? Often it saves a portion of the in-progress drafting, but not always. What is the fix?

I had a compact card view in 115 that automatically changed itself over to a new expanded card view when a Thunderbird version update in Linux Mint 21.3 changed my Thunderbird version to 128.

Here is a screenshot of how I used to have my inbox and I want to keep it that way now but I don't know how.

The first picture is how I had it setup before in 115 and I want to keep that format for 128. The second picture is what TB automatically changed my view to after the update. I didn't manually make any changes.

I have a userchrome.css setup already and it is making some changes but not everything I want anymore. How to I change the userchrome.css to revert the view? I want the colors and size and everything of the lighter color as well as the multi line view.

My userChrome.css is available to view here:

I know userChrome.css isn't officially supported but I want to try anyway.

When I try to change the number of days messages are kept in my inbox (from the default of 30), I get a pop-up window warning me that this will permanently delete the messages and do I want to proceed (see screenshot).

While that pop-up window is up, I can't increase the # of days to retain messages. May I press "OK" and then adjust the number of days messages are retained? Or, if I press "OK" will that immediately delete all messages older than 30 days?

Thanks!

When I received my automatic upgrade to V141 64bit for windows 11, I can no longer put my default signature ABOVE the quoted text, even though it is set to do just that. It puts it below the quoted text.

I'm running Thunderbird 139.0 on Windows 11. I would like it so TB only saves an email to my sent folder when requested. Currently, it always saves every email to the sent folder. I have "Place a copy" disabled in "Copies & Folders" under Account Settings. I had this same problem running TB 141. I had to revert to 139 due to a different problem I was having (discussion for a different post). Any suggestions what else I need to do?

No new messages after opening Thunderbird

Since yesterday (24/07/2025), when I open Thunderbird, I don't see new messages. I can see the number of new messages, but no new headers. I didn't have this problem before. When I access my account through a browser, there are new messages that Thunderbird doesn't see. I have version 140.1.0. I have the message threads enabled - All.

Polish/Polski Brak nowych wiadomości po otwarciu Thunderbirda Od wczoraj (24-07-2025) po otwarciu Thunderbird - nie widzę nowych wiadomości, widać liczbę nowych wiadomości, ale brak nowych nagłówków. Wcześniej nie miałem tego problemu. Jak wchodzę na konto przez przeglądarkę, są tam nowe wiadomości, które nie widzi Thunderbird. Mam wersję 140.1.0. Mam włączone odnośnie wiadomości - Wątki - Wszystkie.

i've been using thunderbird email for years now & have a recent problem (maybe the last 8-10 months? where i send an email & then someone replies & then i reply back to them & etc etc etc & every time i go to open 1 of the emails in the thread all the emails are displayed across the screen but separately, i hate this, i want each of my emails send & each of my emails rec'd treated separate!!! they used to be but i don't know what's changed & i've used all my limited experience trying to find a setting that i can change to fix this?? any ideas??

Before this new computer (this week), I had a 'go' button in Thunderbird that allow me to move to a specific folder without scrolling through all of them (I have hundreds of folders in TB). When TB was put on this new computer, it doesn't have the 'go' button, and the techies can't find it, and I can't even find any information on it. HELP!!

Thunderbird 138/139, Windows 11 Pro 23H2. While composing a message, after a few lines the app freezes. Both the compose window and the main TB window freeze. Only opening the Windows Task manager allows me to close them. This did not happen with earlier versions.

If I save the message every few seconds while composing I can get most of the message back and continue after restarting TB. This behavior is the same in both the normal and troubleshooting TB modes. I can't even find a crash log to send to Mozilla.

Where shall I look next?

Thank you!

Hello, I've come across a rather strange problem. I have a phplist mailing list (on domain1). When sending emails, I usually also add an image (as a link to the image). Since the beginning of June, however, I've noticed that Thunderbird doesn't display the images added in this way. Instead of the image, it displays an empty frame (a completely empty frame without any tags). Even if "Allow remote content in messages" is checked in the settings. Other email clients (outlook, gmail, roundcube) have no problems and display images without any problems. However, if I put the image on another domain (domain2) and put a link to this image in the email, Thunderbird also displays it. So: it doesn't display the image from domain1, where I have the mailing list, but it displays the same image from domain2 (in the same email from the same mailing list from domain1). Is it possible that Thunderbird is blocking the display of images from a certain domain?
