I am reporting an issue with message filters in Thunderbird.

When the UI language is set to Japanese (ja-JP), the “Perform these actions” section in Tools → Message Filters is not displayed, making it impossible to configure filters.

Environment OS: macOS Sequoia 15.6.1 UI language: Japanese (ja-JP)

After switching the UI language to English (US) and restarting Thunderbird, the actions list appears and filters work normally. Switching back to Japanese reproduces the issue.

This seems to be a Japanese localization-related bug.

Thank you.

After finally getting my TB installation up and organized (v140.6.0esr), COMCAST/XFINITY just acknowledged that they are having issues with 3rd party email programs. At least with Mozilla Thunderbird. Sheesh!

Hello All and Happy Holidays,

I work at an IT repair shop and am having the most difficult time attempting to migrate Thunderbird data from a customer's old PC to a new PC. I followed the steps of copying/pasting the data, and it mostly works. The primary issue is that it did not bring over all the local folders that he had saved apart from his IMAP account. The customer is an ex computer science professor and is going blind, so a lot of his relevant information is organized within these folders. Key issues that have made this different from a typical install: -Profile & Local folders are stored in his old OS drive (that is now D:) D:/~/user/appdata/roaming/Thunderbird/~ -files are more than 2GB, so I'm unable to export as .zip -His folders are alphabetical, and every time stops at a particularly larger folder that starts with a D (which had considerably more folders than many others)

The only solution I have come up with is copying/uploading the local folders to his IMAP email, but not all emails are being uploaded either. However, has been more successful than the other migration method, but this has to be done a single folder at a time and not all contents of folder are transferred...

Is there some type of script or other way to migrate these local folders?

Any input is appreciated.

Thanks

Config editor has no printer listed. nothing to reset. Printer works with other applications just not TB. Re-installed the printer. Reset the space limiters, which I found were set too low. Restarted TB and computer

hello

I don't seem to be able to attach and display a photo while sending an email. I transfer the image over but all that appears is a small square with no image displayed. Attachment doesn't seem to work either.

I'm on a MacBook Air

any help would be appreciated

I use Chrome as default Browser However if I click a link in an email, it often opens EDGE

Google search says to change default app settings in Windows and settings in Email client.

The former has been done and W11 uses Chrome ...... are there settings I cna change in TB for this ?

Hi, I am using Fibrus email (network name is HomeWifi and network key is Fibrus123). Fibrus uses eero as a modem. I cannot work out the correct server settings in Thunderbird as there doesn't seem to be a place for 'network key'.

Most grateful for any help you can give me.

Is there any hope for us to have syntax which allows for advanced search through all the folders of a different account? Something that allows powerusers to type something like: "from:XXX to:YYY subject:"foo" after:20d" and get results?

I'm currently parsing all my email with notmuch locally to get something like this. It would be great to be able to get this type of functionality in Thunderbird natively. There are some adons that I have found but they seem like hacks; search needs to be super reliable.

I'm slowly persuading my wife to move over from outlook to Thunderbird (due to constant issues with google sync). I've got it all setup nicely and working BUT i'm having a real issue with the thunderbird calendar taking an absolute age to populate It is quite a well used calendar with lots of recurring events/reminders to pay bills etc. Just to get the Holidays in United Kingdom takes about 30 seconds and to populate from the gmail calendar takes around 8 minutes

It's the one stumbling block i'm finding to persuade her to move over so any advice that can be given would be greatly appreciate

Suddenly last week, the behavior of my Local Folders emails changed. Double clicking caused a reply-to default, not an open in a new window default. All sub-folders seem to have this problem even new ones. Right clicking shows a menu where New Message From template is the default. No other accounts have this problem, but Local Folders is my main email area. Flags show the Inbox as an Inbox, not a Template. Opening a new subfolder under Local Folders indicates that Local Folders is renamed somehow as Templates somewhere in the underside of Thunderbird. I see threads about recent All Mail issues, but this seems different. I have also tried JustAnswers but am unsure that the issue will be fixed with just redoing the Inbox folder. I have also tried the Conifg Editor to change the default right click menus as recommended in various help forums but to no avail. It looks like some part of Thunderbird is handling Local Folders as before, but other parts are assuming it is a Templates folder with Templates characteristics, which it is not. Is there something else I should try?
