Enhances Rightmove, Zoopla, OnTheMarket, PrimeLocation, PropertyPal, PropertyNews, and OpenRent by showing key property details like floor level, parking, and pet policy at a glance.

Features & Capabilities

Find your dream home faster! Stop digging for property details.

Tired of endlessly clicking into property listings on Rightmove, Zoopla, and other major UK portals just to find the information you really care about? Property Previewer revolutionises your home search by showing crucial details at a glance, directly on the search results page.

Works seamlessly with Rightmove, Zoopla, OnTheMarket, PrimeLocation, PropertyPal, PropertyNews, and OpenRent — with more sites coming soon.

Our smart extension enhances property listings by displaying a convenient preview panel with key information that is often buried in long descriptions. Sign in for a free account to save properties across portals, track price changes since you saved, and hide listings you don't want to see again.

Key Features:

  • At-a-Glance Preview Panel: See crucial property details without leaving the search page. Displays key info such as Availability Date, Postcode, Floor Level, Furnish Type, Parking, Garden, Floor Area, and Pet Policy.
  • Save & Organize: Save properties to a default collection or your own custom collections — across all seven portals. Tag each with a status (New, Shortlisted, Viewing, Offered, Dismissed) and hide listings you don't want to see in search results.
  • Notes: Add a personal note to any property, from the listing card, the preview, or your saved list. Press n on any property page.
  • Price-Change Tracking: Every saved property captures the price at the moment you saved it, then shows the delta against the current price (↓ £15k since you saved). Sort your saved list by biggest drop.
  • Activity Status: Each saved item shows an Active / Quiet / Stale badge so you can spot listings that may have been removed without clicking through.
  • Price History Tracking: View crowdsourced price history for every listing — helps you gauge value and negotiation potential.
  • Contextual Extracts: Shows snippets from the original description so you can see where each detail comes from.
  • Quick External Links: Jump to useful resources for each property — Google Maps, Directions, Street View, local area info from Streetcheck, Crystal Roof, and StreetScan, plus the Index of Multiple Deprivation (IMD) Map.
  • Keyboard Shortcuts: Browse faster with your keyboard — j/k to move between listings, p to show/hide the preview, s to save the current property, x to hide it, n to add a note.
  • Floor Plan Analysis (Experimental): When details like floor area or level are missing, it can attempt to extract them from floor plan images using OCR.
  • Supported Portals: Rightmove, Zoopla, OnTheMarket, PrimeLocation, PropertyPal, PropertyNews, and OpenRent.

Amazing how it can speed up sifting process of endless adverts. You can see all the basic information, like sq ft; set up your desired commute desitanation and check out the route, etc. Essential for house search, 10 out of 10

Is Property Previewer Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Property Previewer requires very minimum permissions.

Risk impact analysis details

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Property Previewer is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
