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?

XP FF68esr needed upgrade, wont sync, blue snake chasing tail. Installed Linux and FF78 (dual boot) on same machine. Deleted key4 cert9 and places carried over key3 cert8 and logins from xp68 and got everything back in order and working, except for sync. I was running FF79 on my Firestick and login to my FF account I could see the Linux machine but no sync between the two. I just installed FF120 Nightly on the Firestick to try to get used to it, but it wont sync to the Linux. It did sync to the FF79 on the Firestick however.

I've got an old Windows XP computer running version 52.9.0. I'm trying to sign in to Sync (so I can sync with my new Windows 10 computer) but when I try on the old machine I get this error 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.

I've signed in on the new computer, not that it matters.

Is the any way I can connect to Sync?
