It errors out everytime I try to add it to my Firefox browser.

It's great when it works which is almost NEVER.

This is an essential part of book marketing! Thank you!

I can't work out how to get started or how to access my data

When it works, it's great. But it can be a bit rambunctious.

Extremely useful tool for self-publishers. Been using it for years. Would absolutely recommend.

Book Report is so much easier to read than the reports that KDP provides! And it's customization so that you can look at just the data that you need. I don't know how any self published author functions without it honestly.

BookReport is an essential aid to all self-publishing authors. The simplest, most reliable and all-round excellent revenue tracker, it enables you to see strength in your sales as well as trends and, best of all, it just works.

I’ve been using BookReport since it launched and none of the competition compares.

Excellent extension. This makes using Book Report MUCH easier as opposed to having to be on a certain KDP page before the plugin can access your book data. This extension works fast and as of this review, works well. Highly recommended to all authors!

As an author, data is incredibly important and Amazon's own data charts aren't the best. I don't know how I ever survived without Book Report. This new extension makes it even easier to access all your data and works flawlessly. If you publish on Amazon, you NEED this in your life.
