I cannot checkout in amazon.com using Firefox 9 or 10 - 8 or earlier works fine.
After clicking on "checkout", amazon.com asks me to login. After that, I get a blank screen. This happens with version 9 and 10 of Firefox. If I use version 8, then everything works as expected. Logging in to my amazon.com account from any other page also works as expected in any version of Firefox. But to checkout you always have to login again, and the problem still happens.

The problem has been solved. There was an entry in my user.js and prefs.js files which was user_pref("capability.policy.default.Window.onunload", "noAccess"); When this was removed, the checkout process worked as it should.
