Yes, I have tried with all browsers, and on several different computers. The result is the same.
This does not give me a good first impression with them, unfortunately.
I wish I could call them but find no phone number so I left a case message inquiry on their website.
I thought perhaps someone else may have had the same problem.
I do not have that problem, i'm using Google Chrome. I also see a lot of people talking about setting up with Coinbase and this is the first time i hear of this issue. Maybe you don't have JRE installed or something.
Keep an eye out for their chat support, whenever i had an issue or a question in the past, the chat was available and i was able to get a prompt answer. One time they forward it to a ticket and i got a reply by e-mail the next day.
also sometimes proxy have issues with there services check if you have it on you network or where you have tried it
