Loading pages fail and unable to sign in in order to sync.

I was having trouble with Firefox not loading pages. I upgraded from v57.0b9 to the latest one (out of desperation), which didn't help. I've now reinstalled v57.0b9 but can't sign in in order to sync. Any ideas?

Attached is the message I get when trying to sign in.

Hi Ian, Firefox 57 is no longer supported. On Windows 7, you can run either of the current releases:

  • Regular Release: Firefox 96
  • Extended Support Release: Firefox 91esr

Since your Sync isn't working, you may want to create a file backup before the update:

More generally, a CSP error can occur when a page is opened in a frame. I don't know why the Firefox Account login page would open in a frame. Seems suspicious. You may want to run some malware scans: Troubleshoot Firefox issues caused by malware.
