The question is unclear, but here is some information from Mozilla.
How to develop a Firefox extension
and
You will find the code of all installed extensions in the firefox profile folder. In my vista machine, it is located at C:\Users\<ur name>\appdata\Roaming\Mozilla\Firefox\Profiles\<randomstring>.default\extensions\
Unzip the jars and learn the code, edit as per your needs and restart firefox. Remember that when firefox automatically updates the extension, ur changes will be overriden. If something goes wrong, start firefox from cmd with -P switch to create a new profile or goto safe mode using firefox -safe-mode
and uninstall and reinstall the extension from its website.
