MultiLogin Chrome extension modification

Please bid only if you have good experience with javascript and chrome extension building. I have attached a chrome extension file with this post. It works with most of the websites but doesn't work with this website https://cgifederal.secure.force.com/?language=English&country=India, I want you to make changes to the existing chrome extension which I have attached to work with this website.

PS: For testing, you can make dummy accounts. The website doesn't ask for an email verification for creating new accounts .
