https://hg.mozilla.org/mozilla-central/diff/02cecde2f137/browser/locales/en-US/chrome/browser/browser.dtd There's no way to tell what "Extension" means here without a localization comment. It could be a TLD, or an add-on. Not sure if someone wants to keep this as a good first bug for new contributors.

Comment on attachment 8812911 [details] Bug 1318910: Provide a localization comment for urlbar.extension.label I'll go ahead and ask for aurora approval, hopefully we'll avoid errors. Approval Request Comment [Feature/regressing bug #]: - [User impact if declined]: lack of comment might cause wrong translations [Describe test coverage new/current, TreeHerder]: - [Risks and why]: none [String/UUID change made/needed]: only a comment added, so you'll need l10n=(reldriver) to land
