From what I can see online, the instructions are, read the QR code and everything works. I've also seen a lot of wondering about QR codes not working. I get QR codes, but Thunderbird can't read them. Seems to be a bug in the QR format.

Hi, i copied my Thunderbird (windows 10 Prof)) to a new Notebook (windows 11 Prof) by overrighting the Standard-Profilfolders (in ROAMING and LOCAL) of the new Installation with the Folders of the old Installation (both are Version 146.0.1 but old is 32-Bit and new is 64-Bit) I use more than 2 accounts, and in some accounts, I created subfolders in the 'In' folder to preselect the emails by rules after they arrive Result is: alls Subfolders are missing and some accounts' 'In' Folder are empty. The Account settings seems to be corrct, means i can load new EMails even if the IN-Folder is empty. But i miss the exosting EMails there and the Subfolders content.

I just installed Ubuntu 24.04.3 LTS to an old computer and I want to export my profiles and contacts from my other Windows computer Thunderbird, over to the new Linux version of Thunderbird. I suppose the other option is to re-import from Gmail contacts. Please advise. As others migrate from Windows to Linux this could be a common question.

I've been using Thunderbird for years under windows 7 and keep my data on a separate drive. Is it possible to migrate or move the whole program and data base into Linux at a later date? I haven't used Linux yet, but need to know if it's possible to successfully make the move before I jump. Thank you.

I didn't find anything quite like this in the forums.

I have a new windows 11 laptop. Transferring from a windows 10 laptop. I have installed Thunderbird on new machine. It is also my email on old machine. I have clicked on import within Thunderbird. The instruction is to go to C:/Users/myusername/AppData/Roaming/Thunderbird/Profiles/b4553kng.default NB I can't find backslash on my keyboard, so I'm using / When I look in myusername, there is no folder called AppData There is a folder called Roaming, but it just has folders Intel/Wireless, which is empty. In C: Program Files, there is a folder called Mozilla Thunderbird, but it has no folder called Profiles. I have seached C: for any folder called AppData, but no results. Can anyone help?

I've saved my thunderbird data from Win10 computer following the instructions but when I copy the file to the new computer win11 it doesn't seem to work I'm not sure whats happening. The process I followed is install thunderbird, go to help menu, trouble shooting , open file (profile), close thunderbird, go up 3 levels to roaming, then paste the copied file in the thunderbird file and close. then open thunderbird. It still wants me to set my account up and there is no data. Is there something I'm missing. Thanks for any help in advance. Cheers Stuart

Have TB on my laptop (146.0.1 (64-bit) on Win11) all set up the way I want it. Would like to "clone" those settings/profiles to my desktop. AI site said, "Copy profiles folder and profiles.ini to the new machine." Didn't work. Asking me to set up from scratch. Laptop is on "standard" edition, think desktop is on beta. Is that the problem? What do I need to do?

I changed operating system from Win 10 to Linux. Can I import the file or files from my Firefox on Win 10 to my Firefox on Linux? If so, where can I find them on the windows drv and what is the file called? Thanks for your help Ray

I need to import my passwords from Bitwarden. I can export them from Bitwarden as a CSV file, but that doesn't show as an option in the Import Data window in Firefox. I use MacOS 10.14.6. Thank you, Tim
