Hello there we have read the question We try to help

Using programs together can come together .the accepted code can be on the wrong place or is coming with the use of PowerShell or other software that could explain this rare appearance for having them located there suddenly.Or a guid error or placing mistake. The Mail archive app X ain't having much security to. Could be a minor fault in the css style or html code s but that is out of this subject.

It s more like a read and thanks code.

https://support.mozilla.org/en-US/kb/how-to-make-screenshots Can you send me a picture/screenshot of the complete page with these code?

Powershell on macOS is rather unlikely. I see the hex codes on both Sequoia and Big Sur.

Screenshot of the Thunderbird mailboxes is attached.

Hello

Oke I do have received that picture, oke.

Hello there

Correcting this topic can start with correcting the imap folders to delete them by deleting the msf.files and restarting them, but this will not affect the account name that has to be fixt that you use there. Updating your email server can do something ?a folder of yours on the email server pretends to be hidden and doesn't pass on any good things. Is that a hex code? Greetings Firefox volunteer.

This is my test account which I use with Mail, Outlook, Postbox and Thunderbird on 2 computers. Only Thunderbird shows this problem. And the accounts on both computers are brand new.

Hello there

You might erased some other functions of that account ? Is it after an back up possible to remove the complete map? Greetings Firefox volunteer
