I don't think that this is an opinion if it happens regularly, on any
machine I tried (both 32 and 64 bit).

Here are some more hints:

It happens every third page when connected to Outlook web access. There
are some controls originally written in ActiveX and reimplemented in
JavaScript that cause Firefox to hang.

Similar pages (e.g. developed with Visual Studio) trigger the same
behaviour.

Additionally, pages relying strongly on Adobe Flash Controls hang as
well. However, I did not pin them down so far.

Currently we develop a web site using Jquery, Dojo and other Toolkits.
Pages that use them in combination get stuck as well (5 to 6 calls, then
a hang for approximately 1 min).

Also Firefox hangs in a Mutex_wait indefinitely after 5 to 6 launches.
This to me looks like a dead lock somewhere (without having looked into
the code of course).

I am happy to do further investigation if someone provides the
direction.

btw: None of this happens with Chromium.

Title:
  Firefox hangs in Oneric

Status in “firefox” package in Ubuntu:
  Opinion

Bug description:
  Every other page firefox will hang for approximately 1 - 2 minutes.
  There is no indication that the same page hangs
  It does not come regularly (sometimes, calling 10 to 20 pages works fine, sometimes it happens after the second page, no longer than 30 pages called)
  System Monitor indicates firefox process being Sleeping with poll_schedule_timeout (not very informative)
  Compiz renders the windows gray
  I happened only after upgrading to Oneric

  Chromium does not show any of these signs (I did a parallel test on
  this)
