I'm confused why I can't find anything like this for any other extensions. Is
there a different way to have localized strings in the extension?

I actually follow the pattern file browser use:
http://code.google.com/searchframe#OAMlx_jo-ck/src/chrome/common/extensions/a...

It has a getStrings function to get the localized strings.
