Strange. But I do only see Mon-Sun on my desktop computer, which is running FF60 (even in incognito mode). On smartphone (Opera) or Chromebook it's still Sun-Sat for me.

I wondered if it could be something like that, but I'm US-based, and have not done any Europe-origin searches lately (nor VPNed to Europe) and I've only noticed it in the last day (which is roughly when I got the FF60 update)
EDIT: which doesn't rule out I guess that FF60 somehow makes it appear to ITA that I'm in a different locale.
