Using a search engine for discount codes works better than this resource-eater. On top of that this addon also scams their advertisers out of their affiliate rewards.
No reasons to keep this bloatware.

This extension scams your fellow content creators out of their referral commissions.

Man in the middle attack. Mocks non-existing coupons to change and reconstruct affiliates to falsified links, methologically stealing commission money without user consent.

Scam, do not install

It's a scam, it lets storefronts control what discount codes to show you, and only pretends to search the internet for codes.

Installed for a couple weeks, it never worked(never had a working coupon code). I promptly uninstalled

This add-on is a scam. It hijacks content creators' affiliate links and doesn't actually find you the best promo codes available. They also sell your data.
