Firefox add-on description localization

Question

I've created simple restartless Firefox add-on and trying to localize it. I can not localize the add-on name and description. I'm trying to do it as it is descriped here Localizing extension descriptions

Below my install.rdf file and package.json

package.json

{
    "name": "find_in_files",
    "title": "Find in files",    
    "id":  "{7DE613B7-54D9-4899-A018-861472402B2E}",
    "description": "Search for substring in files",

    "version": "1.1",
    "unpack": "true",
    "preferences": [
        {
            "name": "SearchDirectory",
            "title": "Search directory",

            "type": "directory",
            "value": ""
        },
        {

                },
                {

                    "label": "Russian"
                }

What am I doing wrong?

Answer 1

The answer is - the command "cfx xpi" from mozilla add-on sdk will overwrite install.rdf if you have it in project folder. So, to get things work properly - create xpi package, unpack it (unzip) - and you will find auto-generate install.rdf inside (!!!), substitute install.rdf with your own and re-pack xpi with zip command.

That's all, folks!
