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

I'm trying to sync from Windows XP to Windows 8.1. When I sign in on XP I get a completely blank page and a few buttons. When I click on 'Reconnect to sync' I get the message "Blocked by Content Security Policy. This page has a content security policy that prevents it from being loaded in this way. Firefox prevented this page from loading in this way because the page has a content security policy that disallows it". What other way is acceptable?

Good morning.

59.9.0 (32 bit) running on Vista Home premuim; yes I know it's old.

Path : Tools/Options/Sync

Presing the 'Sign in' button gives and error "Blocked by Content Security Policy - This page has a content security policy that prevents it from being loaded in this way.

Firefox prevented this page from loading in this way because the page has a content security policy that disallows it."

I was signed in to an account on old and invalid email address, I exited the account, with the Idea I'd be able to sign into the account my laptop and phone are linked on. The afforementioned message appeared.

Is it possible to circumvent the relevant security policy, and if so how?

I can be reached at Phil.Davis9@gmx.co.uk.

Kind regards,

Phil Davis.

A few days ago I was told via message that firefox will stop support for windows 10. I ungraded my system to windows 11 and downloaded the appropriate version of firefox. Now I'm getting the same message again. Please help. I like firefox but being told continuously that it's no longer supported even though I've upgraded my system to one that is supported is a pain.

I am configuring a new desktop. My university uses Duo for 2-step security. When I use Firefox 106.0.5, Duo returns "500: Internal Server Error". Edge works. I'm assuming this is a new problem since I haven't located any other mentions of it so I'm assuming that this is either a new problem or particular to the University of Alabama.
