To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':
msf > use auxiliary/gather/selenium_file_read
msf auxiliary(selenium_file_read) > show actions
...actions...
msf auxiliary(selenium_file_read) > set ACTION < action-name >
msf auxiliary(selenium_file_read) > show options
...show and set options...
msf auxiliary(selenium_file_read) > run
