You know the blue bar at the top of Facebook? The one with the search bar and the notifications on it? Well it’s disappeared from every page other than my own profile.

Not too bothered about Facebook but the admin controls from the top of my WordPress website have also vanished. The links are still there and functional I just can’t see them. It’s very bloody inconvenient.

Any idea what I’ve done to stop this particular element from showing?

All works fine in Firefox.

Running an advert blocker? If so, try disabling it, as you may have blocked an element you shouldn’t?

Have Apple dealt with the jerky video in fulscreen in Safari, or is it still crap/they haven’t admitted it’s an issue?

Yes, running an advert blocker and tried to disabling it but it’s not that. It’s happening on any site that has one of those sliding headers.

Not sure what you’re on about with the jerky video but not really looking for an anti-apple rant.

Never heard of this. Have a goolge on Apple support communities inc macrumors.
