Title:
High usage of CPU in Firefox
Status in firefox package in Ubuntu:
Incomplete
Bug description:
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).
