Logged but viewing the coming soon page

Hello,

I usually works with Chrome and while the coming soon page is setup and I’m logged in as admin, I can visualize all the website and bypass the coming soon page which remains for all those not logged in WP.

I though this was works as intended, but when I’ve logged WP via Firefox, I was able to see the backend but not the pages, no matter what I always see the coming soon page even if I’m logged as wp admin, which is a bit odd ’cause I can’t see the result of my work on the pages.

You know why? ty
