Versión 0.5.45
Lanzada el 5 de oct. de 2026 - 132,82 KBCompatible con firefox 140.0 y superiores, android 142.0 y superioresUnderbook is now offered on Firefox for Android (version 142 or newer). On a phone the card stays above the booking site's own bottom bar, its buttons are larger, and its messages say where Underbook is in Firefox's menu. In Firefox's Add-ons Manager the add-on's name and description now appear in Spanish, German, French, Portuguese (Brazil) and Italian; the banner stays in English. On a hotel page that shows no dates, Underbook's card now lets you check that hotel for the dates you last checked, or for dates you pick on the card.Se publicó el código fuente bajo la licencia Todos los derechos reservados
Versión 0.5.44
Lanzada el 5 de oct. de 2026 - 121,18 KBCompatible con firefox 140.0 y superioresOn Expedia, Hotels.com, Hotwire and Orbitz hotel pages, Underbook now checks the dates the page itself shows, even when the page's address carries other ones. On Agoda hotel pages the check starts as soon as the page names the hotel. A booking site's own landing page (goSeek, Kiwi.com hotels, DealBase) no longer gets a card about the site itself.Se publicó el código fuente bajo la licencia Todos los derechos reservados
Versión 0.5.42
Lanzada el 5 de oct. de 2026 - 116,4 KBCompatible con firefox 140.0 y superioresPrices on the Underbook card now name their currency once, in your browser's own style: a Spanish browser reads "43 US$" instead of "43 US$ USD", a euro price reads "€41" instead of "€41 EUR", and a bare "$" or "¥" still gets its code ("$41 USD").Se publicó el código fuente bajo la licencia Todos los derechos reservados
Versión 0.5.41
Lanzada el 5 de oct. de 2026 - 115,67 KBCompatible con firefox 140.0 y superioresUnderbook no longer mistakes flight, package, car hire, train and cruise pages for hotel pages in Spanish, Portuguese, French, German, Italian and Dutch (for example a Skyscanner flights page in Spanish), so it stays quiet there instead of showing a hotel card.Se publicó el código fuente bajo la licencia Todos los derechos reservados
Versión 0.5.40
Lanzada el 5 de oct. de 2026 - 111,68 KBCompatible con firefox 140.0 y superioresNo change you will notice: Firefox already checked a hotel page that was open when you installed Underbook. This version only counts one daily usage ping per install when several tabs start at the same moment.Se publicó el código fuente bajo la licencia Todos los derechos reservados
Versión 0.5.39
Lanzada el 4 de oct. de 2026 - 109,76 KBCompatible con firefox 140.0 y superioresThe request to rate Underbook now sits right under the card's answer, where you can see it, instead of at the foot of the card. It only appears while the page is in front of you and the card is open, at most once (or once more if you chose "Not now", no sooner than 90 days later), and never on a card that offers free cancellation for the same price or less. It can now also come when Underbook finds that the site you are on already has the best rate for the second stay you check. On Firefox its link opens Underbook's page on addons.mozilla.org.Se publicó el código fuente bajo la licencia Todos los derechos reservados
Versión 0.5.38
Lanzada el 3 de oct. de 2026 - 108,1 KBCompatible con firefox 140.0 y superioresWhen a hotel's own site or another booking site lists a lower price only for members who sign in, the card now shows the price anyone can book as the price, and says the members-only price in a short labelled note under it. A members-only price is never shown as the lower price or the best rate.Se publicó el código fuente bajo la licencia Todos los derechos reservados
Versión 0.5.37
Lanzada el 3 de oct. de 2026 - 107,11 KBCompatible con firefox 140.0 y superioresWhen a price check takes longer than usual, the card now says it is still checking and shows the answer when it arrives, instead of giving up after 25 seconds. If no answer comes, or the price service cannot be reached, the card says "Could not get prices right now." with a Try again button, and no longer gives a reason the price service did not give.Se publicó el código fuente bajo la licencia Todos los derechos reservados
Versión 0.5.36
Lanzada el 3 de oct. de 2026 - 104,83 KBCompatible con firefox 140.0 y superioresOn hotels' own booking pages (SynXis, TravelClick, ThinkReservations, Simple Booking), Underbook now uses the hotel's town as the page shows it, so hotels with common names are told apart. When a page prices in a currency Underbook cannot check yet, the card now says plainly that its prices are in US dollars. The price and email fields keep their width on touch screens.Se publicó el código fuente bajo la licencia Todos los derechos reservados
Versión 0.5.35
Lanzada el 3 de oct. de 2026 - 102,13 KBCompatible con firefox 140.0 y superioresUnderbook now works on more hotel pages: hotels' own booking pages (SiteMinder, SynXis, TravelClick, ThinkReservations, Simple Booking and Cloudbeds), full chain hotel names on Booking.com (so "hub London - Spitalfields" is checked as that hotel), uk.trip.com hotel pages, and Accor's results list and booking pages, priced in the page's own currency. The date field fits the card on touch screens.Se publicó el código fuente bajo la licencia Todos los derechos reservados
Versión 0.5.34
Lanzada el 2 de oct. de 2026 - 97,98 KBCompatible con firefox 140.0 y superioresRight after you book on Booking.com, Expedia, Hotels.com or Agoda, Underbook can offer, once, to watch that booking, with the hotel, dates, price and free-cancellation date filled in from the confirmation page for you to check. Nothing about the booking is sent unless you type your email and press the button. It then checks once a day until free cancellation ends, emails you once if a listed rate is at least 5% lower on two daily checks in a row, and reminds you a week before and the day before free cancellation ends. When another site lists free cancellation for the same price or less, the banner now says so. The "−" button shrinks the banner to one line, and changing dates on the page checks again at once.Se publicó el código fuente bajo la licencia Todos los derechos reservados
Versión 0.5.33
Lanzada el 2 de oct. de 2026 - 80,99 KBCompatible con firefox 140.0 y superioresThe toolbar icon now shows "ON" on booking sites Underbook reads and a mark when a check is done. A small tip on a booking site's home or search page says Underbook works there (at most once a day, once every 14 days per site, with a "Don't show tips again" button). Better results for travelers outside the US: Expedia's German, French, Italian, Spanish and Dutch hotel pages are recognized, the hotel's town is read correctly, and prices are labeled with the country they were quoted for. The banner now says plainly that Underbook may earn a commission if you book through its links.Se publicó el código fuente bajo la licencia Todos los derechos reservados
Versión 0.5.32
Lanzada el 2 de oct. de 2026 - 73,1 KBCompatible con firefox 140.0 y superioresBetter hotel detection: Agoda stays checking in on days 1 to 9 of a month now get a comparison; Booking.com keeps your dates after an old link redirects; Trip.com and IHG (including Kimpton) hotels are recognized; your page's currency and a 1-adult party are used; hotel names like "The Ritz-Carlton, Chicago" keep their town.Se publicó el código fuente bajo la licencia Todos los derechos reservados
Versión 0.5.31
Lanzada el 2 de oct. de 2026 - 70,49 KBCompatible con firefox 140.0 y superioresWhat's new since 0.5.25:
- Works on more booking sites and hotel websites: Hotwire, Orbitz, Travelocity, Wotif, ebookers, CheapTickets, Priceline, KAYAK hotel pages, Hilton, IHG, Hyatt, Choice, Wyndham, Accor, Radisson and Best Western.
- One line of room evidence on a lower price: both room names when they match, or a plain note when the cheaper site names no room. Check the room before you book.
- "I already booked this stay": enter what you paid and your free-cancellation date, and get one email if a listed rate is at least 5% lower on two daily checks in a row.
- Share this check: copy a link that reruns the same price check on underbook.co.
- The first hotel page you open is checked right away.
- Clearer banner: one main button per card, readable text, nothing cut off on small windows.Se publicó el código fuente bajo la licencia Todos los derechos reservados
