I can't use the compare feature

[emersoncavalcanti1972]

When upgrading from version 2.7.1 to version 2.9.1, when connecting to any of my ftps saved in the bookmark, I cannot use folder comparison. The menu option appears disabled.

If I open the connection as soon as the program is started by entering the host information, the comparison is enabled. But if I connect to a second ftp, the option will be disabled as well.
