how to run email-extracor - in mozilla in opensuse

hello dear linux-experts

just added the email-extractor to mozilla on opensuse 13-.1

Especially helpful for marketers, job hunters and almost anyone who’s in need of collecting emails to contact them.

The features include

  • Get emails from current browser tab
  • Get emails from entire tabs
  • Copy the emails to clipboard
  • Export the emails as txt file
  • Clear the existing grabbed emails
  • Select from two download locations to export the email list

the email-extractor looks great - i just installed it to firefox (on opensuse)

but i am not sure how to use it.

can you explain how it is used - look forward to any and all help
