JavaScript Deobfuscator (DEPRECATED!)
IMPORTANT: This extension is deprecated, it will not work in Firefox 57 and above. Providing comparable functionality in newer Firefox versions isn't possible.
JavaScript Deobfuscator is a Firefox extension that shows you what JavaScript code runs on a web page, even if it is obfuscated and generated on the fly. Simply open JavaScript Deobfuscator from the Web Developer menu and watch the scripts being compiled/executed. Detailed description
Prerequisites
How to build
Run the following command:
python build.py build
This will create a development build with the file name like jsdeobfuscator-1.2.3.nnnn.xpi. In order to create a release build use the following command:
python build.py build --release
How to test
Testing your changes is easiest if you install the Extension Auto-Installer extension. Then you can push the current repository state to your browser using the following command:

JavaScript Deobfuscator will be updated automatically, without any prompts or browser restarts.
