There is a computer in my lab for everybody's usage. Therefore, we usually used FileZilla to connect others' FTP servers by typing IP and username/password in Quick Connection field. However, we wouldn't like someone else to connect to others' FTP servers without typing anything and just clicking the history in Quick Connection.
I found a way to clean the history. If we choose "FileZilla.xml" to store the site information, open it, and find the tag "RecentServers", then delete them.
We hope that the FileZilla maintainers can add this function for cleaning the history of Quick Connection.
Thanks very much.
