Safari Extension Conflict

Question
1

I found that the new Safari extension Newsguard sometimes prevents the horizontal menu from showing (which is stuck to top of page). Does not happen all the time.

2

What extension is that?

Thanks. And why would you say it’s NewsGuard instead of 1Password or Grammarly?

Process of elimination. The menu was not showing on my first page, so I viewed it with Google Chrome and it was working fine. I then turned all extensions off on Safari and it worked fine. Then I turned on each extension sequentially until only NewsGuard was on and the menu was not showing on the first page. All the other menus were fine - just the first one was missing. So I therefore concluded it was a problem with NewsGuard.
