Convert simple Firefox extension to Chrome and Safari

I have a working Firefox extension that I need converted to work in Chrome and also Safari ## Deliverables I have created the enclosed extension for Firefox, which detects a gmail session and inserts a green check icon at the top of the screen. It uses jquery. I need this extension duplicated for Chrome and Safari browsers so that I can use this test extension as a basis for future development. It should be a very quick project for someone who knows browser extensions. Fully packaged and working extensions will be delivered.
