Diễn đàn hỗ trợ Firefox

I have many computers, all with the same operating system, all with the DEFAULT Firefox install. Only on one computer do I get the "firefox content security policy" error and only when trying to log in via the "sync" tab in Firefox Options to synchronize that computer with the others.

I am a retired computer technical consultant. I'm no pedestrian user. I've been researching this problem for about a year. I've gotten nowhere. My research has come up with no answer for this problem, though there are answers for firefox content security policy that address other problems.

I am a hardware and applications software guru. I have no experience with javascript, and I suspect this IS a jafascript issue.

Can you help me?

Thank you, Graham Fisher
