Solve Recaptcha V2 with Capmonster sitekey

[ineedyou]

I am new member here and hope our community can answer my questions:

1. Could I use sitekey method to solve recaptcha by Capmonster? How can I set it? I just found the thread about using Recaptcha Module by Ghost which solve recaptcha not by sitekey method
2. Could I install the chrome/firefox addon into the browser and using parallel the bot?

Thank you in advance
