Public bug reported: This website is triggering high usage in firefox:
http://www.theguardian.com/world/2014/jul/13/israeli-troops-clash-with- hamas-as-gaza-death-toll-continues-to-spiral It's over 270% in core i7 4700 HQ. This website is the first that I can reproduce this problem in Firefox. Sometimes, with many open tabs, this problem happens, and I need to close and open again. I have only one extension enabled: Ubuntu Firefox Modifications 2.9. And IcedTea-Web Plugin and Shockwave Flash have the option "Ask to Activate". Firefox 30.0 kernel 3.13.0-30-generic x86_64 (happens with 3.14.12 too).
