[Bug 217713] Frequent freezes with recent www/firefox

--- Comment #8 from rkoberman at gmail.com ---
This is an upstream issue with extensions that disable multi-processing. While
I had MP enabled, about:support showed it as disabled by an add-on. I found
that Ghostery is now heavily dependent on MP and, if it is not enabled, Firefox
will slow to a crawl.

The following extensions I was using disable MP:
AmazonSmile 1-Button
Dictionary.com
Xmarks.com

Of these, AmazonSmile is marked as experimental and has not had an update in a
very long time and the Dictionary.com one is not longer available. Xmarks is
still active.

Anyone having a performance issue with Firefox should confirm the state of
multi-process at about:support. I'm sure that there are other extensions that
will disable multi-processing.
