What addons in use? Is “Studies” on?

Sorry missed the link provided. There is no feed. Alternatively in Inoreader (paid version) for instance (and other sources) you can monitor the page for changes.

See “Manage Exceptions” (Privacy in Settings).
Typically, when accessing an “exception web page” you’d (from address bar/^i) open permissions and specifically ALLOW cookies for that site.
