We are looking for an experienced add-on developer to convert an existing XUL based Firefox add-on to use the Add-on SDK. In addition, the existing toolbar uses XPCOM to communicate with a Windows executable, we would like to replace this with a pipe mechanism (using sdk/system/child_process) if it can be done.
If it is possible to use pipes, we'll supply an executable that will read JSON requests from stdin, and write JSON formatted responses (and event) messages to stdout.
So the project will involve
(1) converting the XUL based toolbar ui
(2) modifying the add-on to communicate with our Windows executable via the pipe mechanism, instead of using XPCOM.
