To quote the FileZilla home page:
Welcome to the homepage of FileZilla®, the free FTP solution. The FileZilla Client not only supports FTP, but also ''FTP over TLS (FTPS)'' and ''SFTP''. It is open source software distributed free of charge under the terms of the GNU General Public License.
(emphasis mine).
Chrome may be doing just boring old FTP, which does no encryption.
FileZilla may be doing FTP over TLS, which, just like HTTPS, encrypts the traffic, so just as everything will be encrypted with an HTTPS session, everything will be encrypted with an FTPS session.
It may also be doing SFTP, which is a protocol different from FTP (it's not, for example, FTP-over-SSH) that runs over SSH. Again, just as with anything else in an SSH session, it's all encrypted.
For FTP-over-TLS, Wireshark's TLS decryption mechanisms might be usable here, if you can get sufficient information.
For SFTP, Wireshark currently has no SSH decryption capabilities, so you'd be out of luck there unless some other program can decrypt it.
