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?

The response I received via email did not help. My problem is on the Windows XP computer. I need to sync my bookmarks and saved passwords with my new computer.

So far no one has offered any answers that were relevant. I did receive a email that was useless.

I gave up and just trying to change all my saved logins.
