User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:24.0) Gecko/20100101 Firefox/24.0 (Beta/Release)
Build ID: 20130910160258

Steps to reproduce:

Open firebug and toggle "See flight details" in the body.


Actual results:

Scrolling is prevented.
Firebug exaggerates the bad performance making it horrible in firefox.


Expected results:

Why are these meta tags taking such a toll on the performance of the page?

Weirdly, removing the facebook meta og: and fb: meta tags in the head fixes this particular issue.

Found the source of the terrible performance.

An Addon called Operator was doing odd things because of the opengraph meta tags in the page.

Doh!
