I used to have Windows 10 and was using Thunderbird with Quickbooks POS 18 and if I wanted to send an email in Quickbooks like a purchase order or receipt, it would open up a mailto window in Thunderbird with no issue. I've moved to a Windows 11 computer with the same profile running a 32bit version of Thunderbird, set as my Windows default mail client, even in the registry I've set it there but Quickbooks says I don't have a default email client setup. I've exhausted every search over the internet trying to fix it. Any ideas?

When I try and "Compact" my trash folder, I get the following error message: "The folder 'Trash on redacted@gmail.com' could not be compacted because writing to folder failed. Verify that you have enough disk space, and that you have write privileges to the file system, then try again."

There is plenty of disk space, but there is no option for "write privileges". The trash folder has grown to 632 MgB even though I keep deleting old messages from the trash folder!

In previous Thunderbird versions, when you subscribed to a RSS-Feed that required authorization, Thunderbird prompted for it, just as a Webbrowser would.

I'd enter the username and password, tick the box "Save in Password manager" (or something) and the feed would come in.

I don't know when that changed, but nowadays Thunderbird just says "Feed is unautorized". No password prompt, no possibility to mark a feed as "requires Authentication".

I know I could pass username and password in the URL, but that is rather unsafe compared to saving the password in password manager protected with a primary password.

It seems that there were some bug reports some 21 years ago about the same issue, so maybe this is a regression?

Changing color of the text during composing an email does not work when I use "Choose a color" button. The color in the button changes, but when I click "Ok" the color does not change. The color change works though if: I click "Last-picked color", or when I type color name "Green" or HTML hex, and subsequently click "OK".

How to change the color of text in a composed email when

I am using Thuderbird on macOS.

When trying to run in Safe Mode, and compose a new message, I the Thunderbird stucks, so I cannot confirm in Safe Mode, but I had this issue in the past also on other machines/Thunderbird instances, so maybe someone else had a similar problem, or maybe it is a known issue, already in dev team logs.

Thunderbird 147.0.1 (aarch64, macos, m2)

Team, After spending many many hours creating 14 search-folders that can find all of the right emails in approx. 20 "real" (local) folders.

Then I renamed 10 local folders and noticed my searchfolders disappearing!?

Big panic. Now, only the last 2 created searchfolders where there. The rest was gone. Realizing that the searchfolder config is in a file called "VirtualFolders.dat" I instantly took a copy. Restart Thunderbird: Now only 1 searchfolder was left. The copied virtualfolders.dat file still had 2 searchfolders in it but the rest is gone. There is no other copy/backup of this file.

These search folders are the only thing that generated some sense in gigantic piles of email.

Does renaming local folders KILL Virtual/Search folders?
