How do I directly modify a Google Chrome Extension File? (.CRX)

Question

I\'m not sure in which languages those extensions are, I think the are written in Html, Javascript or JSON. As far as I know they are \"compressed\" in a .CRX file.

Answer 1

Note that some zip programs have trouble unzipping a CRX like sathish described - if this is the case, try using 7-Zip - http://www.7-zip.org/
