I cannot find a folder. I have a very large number of folders (around 300 or more), and at the moment there is one I simply cannot locate. I can see an email that appears to belong in this folder, but when I look into the folder with the correct name, the email is not there. This makes me think I may have two folders with the same name on two different email addresses – but I can only find one of them. How can I search for folders by name and see where each folder is saved? In addition, I used to have a button that allowed me to empty my wastebin, but that button has disappeared. How can I restore it? Finally, Firebird has introduced a new appearance, and I can no longer see functions as headings. How can I return to the previous layout?
