For my own installation of SeaMonkey, I disabled all Comodo roots as
soon as I understood the problem.  I disabled all UserTrust roots some
years ago, for reasons I don't remember.  I have yet to encounter a
problem with any Web site because of this.

The several financial institutions where I access accounts via the Web
-- the Web sites for which I'm most concerned -- all seem to use either
VeriSign or Equifax for their SSL site certificates.  My ISP's Web-mail
interface uses Equifax as does the domain registry where I maintain two
domains.  Amazon.com uses VeriSign.

I'm beginning to wonder what important Web sites do use Comodo.
