• Now in 22 more languages: Chinese (Simplified and Traditional), Czech, Danish, Dutch, Finnish, French, German, Greek, Hungarian, Italian, Japanese, Korean, Polish, Portuguese (Brazil and Portugal), Romanian, Russian, Spanish, Swedish, Turkish and Ukrainian. The add-on follows Firefox's language; in other languages it stays in English.
• Works on 29 more of Airbnb's country sites, for example airbnb.com.vn, airbnb.com.ph and airbnb.com.ro. Firefox doesn't turn on sites added in an update by itself, so the toolbar menu asks you to allow access to them.
• Hotels are listed under their own name (for example "Wilde Lisbon") instead of "Hotel in …" in your hidden list and in the Undo message.
• Dates in the toolbar menu are in the same language as the rest of the add-on.
• If a backup file can't be imported, the message now says so in plain words.
• The add-on now has a PNG icon.
