nit: "Params" -> "Param", though I would actually drop this entire sentence.

[Dane Wallinga, 2013/04/10 00:19:13]

Done.

[Dane Wallinga, 2013/04/10 00:19:13]

Done.

nit: Perhaps "FormsSeenStatus"?

[Dane Wallinga, 2013/04/08 22:55:50]

Doesn't feel right. AutofillManager needs to know how the forms were created,
but I wouldn't describe that as having anything to do with the 'status' of the
forms.

[Ilya Sherman, 2013/04/09 02:17:46]

It's not the status of the forms; it's the status (or "state", if you prefer) of
the renderer-side form manager (a.k.a. the AutofillAgent).  Feel free to come up
with a better name.  Just don't leave it as "Param", which is too generic.

[Dane Wallinga, 2013/04/10 00:19:13]

Done.
