Cannot verify server identity

Me too. I get the same exact message every new page I go to and its not only on my MBP but my iPhone 5 too. I resetted my PRAM and even deleted my system preferences plist file to see if that helps but it didn't. I don't know if its a coincidence but Netflix has been acting flaky all this time too. Thought it was my internet connection or WiFi.

same here! it just started about an hour ago on my macbook air 11" 2012. i have ML all up to date. VERY annoying...please help

Me too. Also wifi drops constantly...hope someone figures this out soon. Strange it happens on day of iPad mini reveal.

Been getting it on my iPhone 5 and ipad for the last hour too. Macbookpro and iMac seem okay. All on same network.

Happening to me too all of the sudden! What the heck is going on? Sounds more like some kind of malware, but I dont know enough about it to be sure.

Count me in too. Got it just after I had loaded photos onto FB about 15 minutes ago. don't know if there's a connection there or not.

I received this same message about 10 minutes ago after I turned on my ipad for the first time today. I hit cancel and no more messages yet.

started an hour ago here as well, on a 1 month old retina mbp .... definitely thinking something is going on witht heir cert, it cant be individual computers

"their certificate"? You mean Facebook? I dont even use Facebook and it keeps popping up on sites completely unrelated to Facebook.

Same thing is happening to me.

I've tried :

Soft reset

Clearing cookies and history

Deleting fb

Running on and off wifi

So far no luck

Welll static.ak.facebook, (not a dev with facebook api) but i think its what allows you to like things on other websites and have them show up on your facebook feed, warning i could be wrong... Ive noticed it only happens with websites that have features for facebook integration, and websites that dont, well it doesnt happen

I'm getting this message as well and since I'm not so computer savy I'm thinking it's malware or something. If so what do we do?

Same problem here on Mac. Have not tried phone or iPad. Have tried a number of suggestions: reset modem, restart computer, flush DNS cache, reset safari with no results.

Just checked and same problem on MBA.

It's not malware, it's happening on my 4s and iPad. Seems to me it's something to do with the like buttons for fb on websites
