Bug 95915 – Extend third-party storage blocking API to optionally allow blocking all storage

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Vicki Pfau]

The third-party storage blocking API should be extended to allow a user to block all storage instead of either no data or third-party data. This mirrors what we already have in place for cookies.

This seems bad.

Since there's a test failing, I did more of a "glance-over" instead of a full review.  Seems fine as a general approach.  I'll look more closely with the new patch that resolves the failing test.

This should be exposed as an enum, not a uint32_t

There's precedent for this - See WKPreferencesPrivate.h for a directly comparable example.

I'd like you to consider making the changes I suggested, but won't hold up the patch any longer.

It reads better to me if these enums move from most permissive to least permissive.

-Allow All
-Block 3rd Parties
-Block All.

Same comment.
