I can't type in fill-in fields from time to time, example - login/password fields, google search field. The issue is not connected to particular sites, in fact on one and the same site I sometimes can enter login name and next time it stays blank and does not accept any text; at the same page I might be able to type in one field but fail in another. I can at the same time try to connect to the same site with Safari and type in the same fields without a problem.
