Add The Amazon Publisher Studio Extension
OK...This is simple. In Chrome or Firefox go to the Chrome Store or Firefox equivalent....or Amazon....I would explain how to find these but its simple and if you don't know where to find Firefox/Chrome Apps/extensions (should be in your bookmark toolbar) then either go to Amazon and find publisher studio OR simply do a google search for Amazon Publisher Studio and youll get the direct Amazon link.
Lets assume you know how to find Firefox/Chrome extensions in your store (ps...this is free)
Search for Amazon Publisher Studio and you'll see....
Remember:This is an extension not an app, so make sure you're searching in extensions....
Click the extension and you'll be taken to the main page
In the top right hand corner you'll see "Add to Chrome" (or the firefox equivalent)
Click that
Then you'll see it says "Added to Chrome"
And it's that simple....
On your bookmark/app toolbar you'll now see...
That little orange Amazon tag is what you're looking for...
Click that and it'll open a popup window ....all you need to do is sign in...
Now you're ready to go
