This extension opens a new tab every time you click to copy a coupon code. For example, I'm already on Amazon's website, and it'll open up several new tab. Disabling pop-ups in the add-ons settings doesn't stop this annoying behavior.

very good but i think a way to add unsupported items would be best, theres way too many times i try to add a item and its not allowed.

The extension works well, but it causes some websites to freeze or lag.

Automatically Opens a new tab whenever I click on Karma. Not sure if that's how it's supposed to work, but it is very annoying to be honest.

Would give it five stars if Karma didn't treat the Firefox version like the poor man's Chrome add-on. This one only has about half the features, and so only deserves about half the stars.

Super helpful but the function is sometimes glitchy. Some of the options like sizes, discount notifications, etc. are not fully displayed when you save an item.

Works okay, but annoying. There are coupon alerts that pop up all the time, and no way I can find to disable them. Also, the little shoptagr widget hovers on the page and constantly reminds me that I can tag things. I KNOW. I would rather have the option to completely disable the little hovering widget and just use the icon and the taskbar to save things, with no reminders thank you. I think most people are looking for less spammy pop-ups and reminders, not more.

Not accurate. By the time the product notice of saved items arrives and I click the link, the item is always gone or never in the size I indicated. It can be really frustrating.
