Attachment window gone

Mine's still on top R. corner. What happens in [[Troubleshoot Mode Thunderbird|Troubleshoot mode]]?

So when you add an attachment, it does show at the bottom of the email, it still shows in the window at the top right?

''<p>dantree [[#question-1572910|said]]</p>'' <blockquote>What happened to the useful top right window box for attachments on my outgoing emails, can I return it? </blockquote> I understand that you mean the attachment '''box''' (and not the attachment button) in the top right corner o a "write" window as shown in my picture Since version 91 it has been moved from the top right corner to the bottom https://support.mozilla.org/en-US/kb/new-thunderbird-91#w_new-user-interface-for-adding-attachments There had been an add-on https://addons.thunderbird.net/en-US/thunderbird/addon/morelayouts/ which allowed to replace the attachment area to thee top right corner but it is no longer compatible with recent TB versions Some user in the German TB forum succeeded to move it back to the top with userChrome.css but I wouldn't recommend this.
