Hello Please, how can I make Thundebird from main search menu (on the top) to sort the results automatically from newest (forever?).

I get them always from oldest.

I sort them.

Even when I click the small icon on the right, and make "descend", by new search, I get those oldest at first :-(

With the years, it slowly sucks.

Thank You.

Is there a font setting to change JUST the font size (event title field) that is displayed on the TB Calendar monthly grid view. Was able to change overall size in TB, but did not really want same change on mail views? Perhaps a specific TB setting (or userchrome command)?

Yes, I did see the question on Calendar Event font size changes, but not applicable to this as I read it...

Thanks for any suggestions, if any....

Context: Windows 11 23H2, Thunderbird Portable (102.15.1, stubbornly declining updates until the Supernova IU starts looking tolerable), Avast Antivirus. Multiple email accounts on various servers, all POP3.

For the last several months (not sure when it started, but I first took a screenshot in October 2024, so perhaps that was the first time), after each time I reboot my PC, the first time I send an email using one particular account will trigger a complaint about a bad certificate, which is probably caused by Avast getting in the middle of the process. Clicking "View..." opens a tab with certificate information. I'm attaching screenshots.

I assume my other accounts also had a similar complaint when they were first used, but it has been a long time since I added a new account and they are all quiet now. But on this account, I get it the first time I send mail (normally a reply to someone else - this is not my default account for new messages) after each reboot. When I click "Confirm Security Exception" with the "Permanently store this exception" checkbox checked, the next thing I get is "Send Message Error" (see the third screenshot), then I click OK, and then I can hit "Send" again and the message is sent with no complaints. Then I can also send future messages with no complaints until the next time I reboot. (I don't reboot often - normally just when Windows needs to do an update.) This is the only account on Dreamhost (others are InMotion or Google), but other than that, there is nothing special about it, as far as I know. Why is it forgetting my "permanent" exception? Is there a setting somewhere that I should look for?

I just now tried following the instructions on this page: https://support.avast.com/en-us/article/troubleshoot-invalid-antivirus-email-certificate But it says, "This certificate is already installed as a certificate authority." Perhaps that is because I have already gone through the process for this reboot cycle, but if TB needs a new Avast certificate or exception each time I reboot (due to something changing in Avast, perhaps), I'd think the first email I send through any server would ask for the exception, but it's never any other account - just this one Dreamhost one. Fortunately it's just an inconvenience, not a showstopping problem, but it would be nice to solve it eventually.

140.0.1esr (64-bit) the main Thunderbird screen showing email list, the menu bar is under the email toolbar not on top, there was several suggestions on the forum on switching the positions using changes to profile with a chrome css file. I tried many with the commands inserted inn the th e.css file but did not help

Imagine having more than 30 Accounts to be added on a single profile my concern is how will Thunderbird handles file size if it's using one file (MBOX) and if the file has no solution, can I create files and keep mails on them until they reach max size?

Your latest request for donations has evidently come with a forced upgrade which I did not authorise. I have been happily using an older version of TB because it supports my add-ons and themes. Now because of your uninvited intrusion they no longer work. Furthermore it seems that I can no longer download an older version that supports my requirements. NOT HAPPY!

Thunderbirdの138.0.2まで使用できていたアドオン「Quick Text」が勝手にThunderbirdが139.0にアップデートされたことにより、突然使用できなくなりました。

例文などをたくさん登録して仕事でも使用している方が多数だったのでクレームが殺到して困っております。

Quick Text が139.0でも使用できるようにしてください！！

The reminders window that normally starts up when Thunderbird opens no longer appears. To be clear it's the window that shows my daily appointments in a separate window. Thanks

I made a mistake. I had 128 and went up to 140. It pretty much looks the same, but a big difference is an extension I always use says it will not work with 140. I don't care how good 140 might be; if I can't use my app, QUICKTEXT, then I don't need this. How do I go back to 128 or to a version that works with my extension?

Good day, I just set up my university account on thunderbird, but cannot receive any mails, I have checked everything listed in the designated page but nothing seems to work, would you have any solutions? Thank you very much (and I know I am not providing a lot of info, it is because I really don't understand what is happening, sorry!)

Hello, How can I change the color on the message email? Right now, it is dark green so it's difficult to read the message. I thought the color is supposed to be blue. Thank you.

Me and my colleague are using the same email account on Thunderbird. How do I delete the account from only my Thunderbird app? My colleague will still need access to it.

Hi all, I have a client who uses Thunderbird and wants to close his orange.fr email address, but has thousands of emails he needs to be able to continue to refer to / archive. I advised to move all the emails from the IMAP server/inbox folder, to a Local folder in Thunderbird. Having done this, I tried to remove the account, did NOT check the box “Remove Message Data” and (wrongly assumed) there would still be a way for him to see his orange.fr emails in a local folder somewhere, but they all disappeared. I’ve tried to trace the path for the local folder but can’t see a way to see them once the account is removed. Can any suggest the best way to GUARANTEE that he can close his orange.fr email account and still retain his old emails? I’m guessing that if he closes the account but doesn’t remove it from Thunderbird, the account will retain the local folders but will be unable to connect to the orange.fr email address. I suppose that would be a solution but I’m guessing Thunderbird will throw a connection error every time it opens? is there a neater way? We would prefer to avoid trying to export them to another mail client.

Any suggestions / advice greatfully received. I’m just nervous that he doesn’t lose access to his old emails after closing his orange.fr email account. TIA Russ

I can't add an account. When I try to add an account, I get an error message: can't access property "cleanup", this[#configVerifier] is undefined The version of Thunderbird is 140.0.1esr (64-bit).

After accidental change to Thunderbird 140.0.1esr (64-bit) all date/time display changed to American format (7/16/2025, 12:55 PM) where it used to be the settings of my machine (Win10 64 bit, language English, region Netherlands): short date dd-MM-yyyy long date ddddd dd-MM-yyyy short time HH:mm long time HH:mm:ss I tried overriding the setting using the config editor and inserted ntl.date_time.pattern_override.date_short and ntl.date_time.pattern_override.time_short, restarted TB which promptly lost the new settings (not saved). Also the Message List Display Options defaults to Cards view after restart, even after changing to Table view.

Please help!
