There are many JavaScript obfuscator online. I recommend Google Closure. The Closure Compiler is a tool for making JavaScript download and run faster. It is a true compiler for JavaScript. Instead of compiling from a source language to machine code, it compiles from JavaScript to better JavaScript. It parses your JavaScript, analyzes it, removes dead code and rewrites and minimizes what's left. It also checks syntax, variable references, and types, and warns about common JavaScript pitfalls.
Note: JavaScript obfuscator doesn't guarantee the confidentialness of the code. anyone expert with JavaScriptcan de-obfuscate that code.
The important code reside on server and extension will communicate with the server and will process the output from server. There are many technologies to communicate with server in JavaScript such as AJAX, JSON, etc.
