FB Marketplace Filter Pro

Filter Facebook Marketplace listings by keyword, scan listing descriptions, and flag new seller accounts in real time.

Facebook Marketplace is full of noise. Salvage titles, dealer spam, financing pitches, sponsored ads disguised as real listings, and descriptions hiding red flags you would never catch without clicking through every single one. Marketplace Filter Pro automatically filters all of it in real time — so you only see listings worth your time. Built for car buyers, collectors, resellers, and anyone who spends serious time on Facebook Marketplace. DESCRIPTION SCANNER — THE FEATURE NOTHING ELSE HAS Every listing that passes your title filters gets a Scan Description button. Click it and Marketplace Filter Pro fetches the full listing page in the background — without you ever opening it — and scans the entire description for your keywords instantly. The scan checks for: — Your custom block list keywords, highlighted in red inside a popup when found — Non-English descriptions — the language is identified by name (Spanish, Arabic, Chinese, Russian, Korean, Japanese, Hindi, French, German, Vietnamese, and more) with a proceed-with-caution warning — Emoji-heavy descriptions that signal low-quality or spam posts — Seller account age — accounts under 2 years old get a caution badge automatically — The full description text displayed in a clean overlay so you can read it yourself and make the call Scan once and the result is cached. Tap the button anytime to reopen it instantly without re-fetching. Even after a listing is flagged, a View Description Scan button stays on the card so you can always pull up the full result. SPONSORED AD BLOCKING Paid advertisements injected into your Marketplace feed are detected and flagged or hidden automatically the moment they appear — no setup required. Marketplace Filter Pro watches your feed in real time using a live observer so sponsored cards are caught instantly as you scroll, not on a delay. YOUR KEYWORDS — BLOCK LIST AND ALLOW LIST No presets, no guesswork. You define exactly what you want to see and what you want gone. Add block list keywords to hide any listing containing those words or phrases — one per line. Partial matching included. Add "rebuilt" and it catches "rebuilt title," "rebuilt engine," and "recently rebuilt" automatically. Add allow list keywords and only listings containing at least one of them will appear. Combine both lists for surgical precision — show only listings containing your target item that do not contain your blocked phrases. Export your keyword setup as a .txt file and import it on any machine in seconds. Ideal for backing up your configuration or sharing a setup with someone else. LANGUAGE AND EMOJI FILTERS One toggle flags non-English listings on the card instantly. Detects Spanish, Chinese, Arabic, Russian, Korean, Japanese, Hindi, French, German, Vietnamese, Thai, Greek, Hebrew, and more. Spanish detection is enhanced — catches accent characters and common Spanish words even in short titles with no obvious foreign characters. A second toggle flags emoji-heavy listings that consistently signal low-quality or spam posts — both on the card and inside the description scanner popup. HIDE OR FLAG MODE Choose whether matched listings disappear completely or are dimmed with a red outline and a badge showing the exact category and keyword that triggered the flag. Hover any flagged card for a tooltip with full details — including whether the match was found in the title or the description. PERFORMANCE — OBSERVER-BASED, NOT POLLING Version 1.1.8 replaces the old polling loop with a MutationObserver. Instead of running a filter pass on a fixed timer regardless of activity, the extension now watches for real DOM changes and only processes new listings when Facebook actually loads them — on scroll, on navigation, or when the feed updates. The result is lower CPU usage, no redundant passes, and filters that fire the instant new cards appear rather than waiting for the next interval tick. ACCURATE SESSION STATS The live stats overlay now counts each unique listing exactly once per session regardless of how many times the feed refreshes or new cards load in. Previously, listings could be counted multiple times as the observer fired repeatedly. Scanned, filtered, sponsored, description scans, keyword matches, and new accounts flagged — all accurate. LIVE SESSION STATS A real-time overlay on your Marketplace page tracks six counters live as you browse — listings scanned, filtered by title, sponsored ads caught, descriptions scanned, description keyword matches found, and new seller accounts flagged. Collapse it to a single line anytime with one click. WHO IS THIS FOR Car buyers — eliminate salvage titles, financing spam, and fake listings before wasting a single minute. Scan descriptions for hidden red flags without opening the listing. Coin collectors — block replicas and reproductions. Require specific years, mint marks, or grades in every listing. Card collectors — block fakes, bulk lots, and damaged card spam. Require specific set names, grades, or editions. Resellers — surface only the items worth your time. Block other resellers already marking things up. Furniture and home buyers — skip the emoji-stuffed overpriced flips and scan descriptions for condition details. Tool and parts hunters — require specific makes, models, or part numbers and block mechanic special and project listings. 100% FREE — NO LICENSE REQUIRED Marketplace Filter Pro is free for everyone.
