This was a cakewalk on Windows, but I'm not sure how to do it on OSX. I'm trying to hand-edit the install.rdf file for Lightning, the Thunderbird extension, to force compatibility with TB 3.0 beta 4 -- but all I can seem to do is unzip the files by renaming the .xpi to .zip, edit install.rdf, and that's it. I can't create an XPI from there that contains the extension files within the root directory, best I can tell, because I'm getting an install script error. And I'm not sure how I can add the edited install.rdf to the originally downloaded archive to "update" the file in the sense that WinRAR does it.
What am I missing?
XPI files on OSX -- how to manually edit install.rdf / other files within XPI?
