and i have seen some suspicious things, for that i commented out those
capability rules.
also, there were problems, in addition to the new messages: firefox said
{ff has been updated, you must restart it} on every tab, if i open them,
and then after restarting, content of that tabs were lost. one of them
has put ubuntu.com at address bar, another become blank.
