Facebook Marketplace extensions compared: filters, alerts and privacy

The comparison table

These are the buyer-side extensions for Facebook Marketplace and Kijiji that we found on the Chrome Web Store with an update in 2026, plus Sift. Each row says what the store page says, in plain words.

How we built this table. We searched the Chrome Web Store for Facebook Marketplace and Kijiji tools on 6 October 2026, kept the ones built for buyers and updated this year, and read each listing’s description and privacy section. We left out tools for sellers (listing, reposting, cross-posting), data scrapers, and extensions that haven’t been updated since 2024, because Facebook changes its page often and stale extensions tend to stop working. We left out ratings and user counts: most of these extensions have only a handful of ratings, and Sift isn’t on the store yet, so it has none.

Which one fits your job?

Ranked lists don’t help much here, because these tools do different jobs. Start from what is annoying you.

• You only shop Facebook and want a hard distance limit. MarketClean (Pro) and Sift both cut listings beyond a radius from a home you set. MarketClean sends place names to OpenStreetMap to work out distances; Sift looks them up in a built-in list on your computer. MarketClean also runs in Firefox; Sift doesn’t. More on the problem in why Marketplace shows listings outside your radius.
• You want to hide a few listings by hand. Hide Listings does one thing simply, with a page to undo what you hid.
• You want to screen out low-effort posts. FB Marketplace Filter Pro reads full descriptions and flags new seller accounts, which neither Sift nor most others do.
• You are watching a few specific listings for a price cut. Facebook Marketplace Price Tracker is the better fit: it checks the listings you pick and sends a notification when the price changes. Sift marks drops and keeps a history for everything you scroll past, but it doesn’t send a notification for a single listing’s price.
• You also shop Kijiji. Kijiji History adds history to Kijiji ads. Sift is the only one in this table that filters, tracks prices and sends alerts on both Kijiji and Facebook Marketplace.
• You resell and need alerts within a minute or two, on your phone. A cloud alert service, below. They cost money, but they keep checking while your computer is off.

For what Facebook’s own filters can and can’t do before you add anything, see Sift vs Facebook Marketplace’s own filters.

Cloud alert services, for resellers

These aren’t browser extensions. They run on the company’s servers, check Marketplace for you around the clock, and send alerts to an app, email or a messaging service. Most need an account and a subscription, and they are built for people who buy to resell.

Before you sign up, read how a service gets to Marketplace. One that asks for your Facebook login, or tells you to install something that runs searches with your account, is acting as you. Meta’s terms say you may not access or collect data from its products “using automated means” without its permission.

Is it safe to use an extension on Facebook?

An extension that rearranges the page in your own browser is about as safe as the people who made it. Five checks before you add any of them, ours included:

1. Read the permissions. Chrome shows them when you add an extension. A Marketplace tool needs to read and change facebook.com (and kijiji.ca, if it supports Kijiji). One that asks for all your data on every website is asking for more than it needs. Chrome Web Store policy tells developers to request “the narrowest permissions necessary”.
2. Never hand over your Facebook password. A browser extension doesn’t need it. It works in the tab where you are already signed in.
3. Read the privacy section. Every store page has one. Look for whether the tool needs an account, whether it sends anything to its own server, and whether it runs analytics.
4. Check the last-updated date. Facebook changes its page often. An extension untouched for a year or more may hide the wrong things, or nothing.
5. Be wary of automation. Tools that message sellers for you, post on your behalf or scrape results with your account are the ones most likely to get an account flagged.

Where Sift fits

Sift is a free browser extension for Facebook Marketplace and Kijiji. It hides what you don’t want to see (sponsored listings and Kijiji Top Ads, listings you already opened, sold items, listings beyond your radius, blocked words, dealers and wanted posts), marks price drops with a dated history, flags listings that ask for a deposit first or want to move to WhatsApp, rates each price against the page, and checks up to 10 searches for new listings as often as every 15 minutes. It needs no account, has no server and collects no analytics.

Its limits, plainly: it runs in Chrome, Edge and Brave on a computer, not Firefox and not the Facebook app. Its alerts run in your browser, so your computer has to be on. And it isn’t on the Chrome Web Store yet. If a tool above does your one job better, use that one. Everything Sift does is listed on the features page.
