Just like plenty extensions, it gives you many promises but doesn't keep any. None of the dozen of codes which were proposed to me worked, all invalid, waste of time.

Had no success with any of the codes and every time I click on codes it opens new tabs.

C'est de la m..., ça vous promet du code réduction mais ce sont des mensonges pour vous faire installer un truc qui n'ira pas.
Alors ça fonctionne peut-être avec certains sites mais comme ça ne tient pas ses promesses je ne vous le conseille pas.

Used it at heatonist, it said "Lucky Day! You just saved $190.00". It didn't actually do anything. It just gives you pop up that the coupon worked, but it didn't

over promises and undelivers

7 out of 10 times I use this app it states that it's saving me money!

7 out of 7 times it removes my good coupons and replaces them with non compatible or expired coupons which costs me money.

Today at the Autozone website, I purchased a 5 quart jug of STP oil, an STP oil filter, an STP air filter, and a can of CRC Throttle Body & Air Intake Cleaner.

The subtotal for those items was $59.26.
The Autozone website automatically found and applied a -$13.78 deal for buying 3 STP products which brought my total down to $45.48.

Ran the CouponBirds app and after seeing SEVERAL "CouponBirds user just saved $XX.XX at Autozone" flash across the bottom of the CB window, the CB app finally decided that it had saved me $7.21 and asked me to tell the world about it by writing a 5 star review.

The app did NOT save me ANYTHING! Instead, it vaporized my STP deal which shot my total back up to $59.26!

Lucky for everyone out there that Autozone makes the deals available right under your total, so 1 click and I was back in business!

SO in my experience with the CouponBirds app, NOT using it saves me Money and no wasted Mouse Clicks!

Doesn't work with my Bank of America access to accounts within my Bank of America site. For example, when I select "pay bills", the browser with this extension stops working. I had to remove it from my extension for it to work. However when it works for some sites, I can save a good bit of money. BTW, this extension works fine on my Chrome extension.

Tried with Etsy. Gave me a bunch of random codes none of them work.

Loading issues on several websites

Installed this a couple weeks ago and started having trouble logging into banking and credit card sites, disabled this (and only this extension) today and was suddenly able to login to those sites again no problem. There is something amiss with this extension, user beware.

The only login method is Google? Login through Google doesn't work, Container Tabs stops it! 😆

Avoid this kind of useless shop-savings extensions that in facts can spy what you are looking on the internet, it's just collecting informations on you to profile you and similar customers to finally target ads/products/services. That's desguished spyware in counterpart to provide you a pretended nice service for free.

And just about the service provided: this kind of extensions (lots of similar exist like this one) can modify the webpages on-the-fly and also can censure some parts or search results to guide you to buy to a specific shop... instead of a concurrent. And guess who is paying the extension editor to do that? Sellers?
Just look at what this extension is requiring at the Permissions part...

Mind again before adding browser extensions!
