C# plugin for Google Chrome
What language(s) are programs like ActiveInbox written in?
I need to write browser plugin, mainly to chrome. This plugin will work with GMAIL. It will track incoming mails and do some actions(put label, delete mail...). - similar what gmail already does by filter option.
My question is: what languages I will need to do this, only JavaScript?
P.S. I've already asked similar question, but it was closed. I hope this time I explained exactly what I need.
Thank you
