Could be incompatibility with Firefox and should really use Chrome to open Google apps.

Hard to help with something we cannot see. Provide steps and links to replicate your issue. This book opens for me from google play store after turning off ETP. see screenshot It was just spinning for me as well.

jonzn4SUSE: thanks for trying it out.

When I open that page and click sample, the book opens.

When I go to "books" -> "your library" i see list of my books. I tried clicking on at least 10 of them. For some reason I could only open this one:

https://play.google.com/store/books/details?id=_KbfCQAAQBAJ

All other books I owned that I tried, I cannot open them, the browser just spinning. I tried opening the following books from my library, but only see spinning loading:

Hopefully this helps.

I could open all the books free samples. Did you turn of ETP from my screenshot?

thanks for your check. When I installed firefox, installation wizard suggested me to install extensions, I installed all the suggested extensions. It suggested "ClearURLs" extension. After I disabled the extension, I could open the book.

I reported this extension.

Thanks a lot.
