When choosing a site-isolated process for a document loaded from a data:
URL that was the result of a redirect, Firefox would load that document in
the same process as the site that issued the redirect. This bypassed the
site-isolation protections against Spectre-like attacks on sites that host
an “open redirect”. Firefox no longer follows HTTP redirects to data: URLs.
This vulnerability affects Firefox < 114.
