UPDATE - It started working normally again. If you use Firefox Developer, I don't think this extension functions properly until the official Firefox version matches the Dev version that you're using.

Solid app. Just saved 25$ on a recent order.

Absolutely OUTSTANDING. I rarely write reviews for add-ons but CouponBirds has saved me so much money, time and time again. Tonight's purchase I didn't expect it to find any coupons, or if it did, maybe must $2-$3.00, but instead I saved $37.35 tonight. CouponBirds is fast, and it just keeps on digging up great discounts all over the web on my purchases. This add-on absolutely rocks!

always saves me so much

Has saved me a lot of money! fast, efficient and easy to use. Ont of the best extensions online!

works great, 30 secs of running the add-on can save lot of money and time

A perfect little tool for hassle free savings!

It actually does what it says ! , definitely worth having -just to get that unexpected discount

I saved $5 on a plushie yippee!

This is my favorite app! It always saves me money and it is so convenient. Usually I had to look up promo codes which meant going to sketchy websites with tons of popups and poorly updated or invalid codes. CouponBirds almost always has valid codes and it is so much easier than having to find them yourself and test them to see if they are working.

Easy to use.

ok

Saves me money and its automatic

Love it, works great!
