OfferUp Item Search od TorranceTech

Search OfferUp listings directly from your Firefox toolbar — no need to visit offerup.com, log in, or create an account. Just type what you're looking for and browse results with prices, locations, and post dates inline.

Features:
- Search without logging in or visiting the OfferUp website
- Sort by Relevance, Most Recent, Lowest Price, Highest Price, or Nearest
- View title, price, location, and post date for every listing
- Click any result to open it in a new tab
- Recent searches saved as clickable chips for quick repeats
- Automatically loads more items beyond the first page

How it works: The extension opens a temporary hidden tab to load OfferUp search results, extracts the listing data, and closes the tab — all in the background. You never leave the popup.
