Easy to use and priceless in potential savings!

Works.

Super useful, it's great for finding out if a sale item on Amazon is a real price deal or not. The alerts are also good for when you need something, but don't need it right away.

La extensión es muy práctica,,,,

great work, but there are some things to do more

Literally one of the greatest addons available! Love that the chart is working in the new firefox, and love that it works on smile.amazon!

hlo

Version 2.9.7 works with the latest Firefox version 59.0.2. An icon shows up in the address bar that contains the price history graph. I've only tried it with a few Amazon products but so far it's working great.

This works great with Firefox Quantum 59. I like that the icon only appears when I'm on Amazon, rather than cluttering up the toolbar all the time. My only quibble is that when I first installed it, it didn't work on smile.amazon.com, only on the regular Amazon site, but this seems to have been fixed now.

Works great with Quantum 59+. Detailed pricing history really kills those impulse buying habits Amazon encourages and offers price notifications set to your limits. Great addon so far, considering how much I use Amazon. Love it.

Love this app! It's like being able to put a limit-order on an amazon item. Getting a message when the price drops below a threshold is awesome. I sometimes buy an item 6+ months after I originally see and mark it on camelizer.

For those complaining about incompatibility, I have been through every update of FF for the last 1.5 years, and am currently on FF 58.0.2, and have successfully used this extension -- alongside ublock origin, print edit, video download helper, user agent switcher, and with and without flash or java.

Love this add on but as other have noted, it is not currently working with Firefox 57+. Please fix!

Functional but graphically dated.
