OrcaView.xpi contains these files:
chrome.manifest
IEMenu.cpp
IEMenu.exe
install.rdf
chrome\orcaview.jar
orcaviewlink.html
orcaviewpage.html
The two .html files are the ones that need to be modified by you.
If you're still having difficulty then let me know the full path and I shall do it for you.
If I have more time at some point, I shall have to improve the coding.
