What is a browser extension?
A browser extension is a small software program that adds new features or functions to your web browser, customizing your browsing experience by extending its capabilities; think of it as a mini-app that lives in your browser.
Extensions can perform various tasks like adding new features to web pages, finding coupons, managing cookies, automating repetitive actions, or earning cashback while you shop.
If you’ve been searching the internet and thought, “I wish I could do X,” there might already be a browser extension that does just that.

Best Browser Extensions to Save Money

Best for stacking rewards: Kiwii
Kiwii helps you max out your cashback, frequent flier miles, and loyalty rewards without disclosing sensitive information. On average, Kiwii users can earn 20X more rewards on all their online purchases.
