Thumper is a side-panel companion for prediction-market traders. Open a market and Thumper instantly shows the same event's price across venues - so you always know where it's cheaper before you trade.

• Live price comparison, side by side, updated as you browse • Cheaper-venue verdict — which side is the better deal, and by how much • Edge & arbitrage detection when prices disagree enough to matter • Order-book depth & price impact before your order moves the market • Payout calculator — enter an amount, see your return on each venue • Hedge & position sizing without leaving the page • Optional desktop alerts when a significant edge appears (off by default)

WORKS ON • polymarket.com • pro.magicmarkets.com More venues coming.

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.

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.

Thumper by MagicMarkets is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
