Title:
  Pages with unresponsive scripts cause extremely long hangs

Status in “firefox” package in Ubuntu:
  New

Bug description:
  This bug makes firefox practically unusable for me.  It seems I run
  into a lot of pages with "unresponsive scripts" (I guess that's what
  it is).  They make firefox hang for a long time before it continues.
  If a menu is up, the hanging causes the entire system to be unusable.
  To see the bug go to the following page (for example) and in the C++
  Documentation section click on the "C++ Language Tutorial" link.:

  http://www.cplusplus.com/

  For me the tutorial page hangs every time I go to it.  It happens for
  pages on github.com, for example and quite a few other pages in my
  presently saved session.
