If you create a single test for the Create() function to ensure that is returns
non-null iff the in-browser feature is  enabled, then you can get rid of this
parameter in all subsequent tests (just always enable the feature and assert
that Create returns non-null).

[ftirelo, 2017/06/09 21:24:55]

Excellent idea. Done.

Now that the Create() function returns a null ptr when the feature is not
enabled, we cannot reach this code if the reset settings is not on. So at this
point profiles 1 and 3 should always be reset.

[ftirelo, 2017/06/09 21:24:55]

In fact, it depends on the registry entries above too. Added a comment.
