How can I localize/access Java Strings from background or content scripts?  
My addon gets the following string from a .properties file via string bundle, then JSON.parse()'s it:

```
actionsjson = [\
  {"code": "AudioFirstActive",\
                  "visual": "Audio Focus First Active",\
                  "tip": "Make first active Audio the current Tab (left)"},\

```

{…next entry…

where “visual” and “tip” can be localized.
