Conditionally enable double key logic according to:
private browsing mode or privacy.thirdparty.isolate preference and
implement in GetCookieStringCommon and FindCookie where it counts...
With some reservations of how to convince FindCookie users to test
condition and pass a nullptr when disabling double key logic.

15 * Declares that a given page uses a favicon with the given URI and
16 * attempts to fetch and save the icon data by loading the favicon URI
17 * through an async network request.
18 *
19 * If the icon data already exists, we won't try to reload the icon unless
20 * aForceReload is true. Similarly, if the icon is in the failed favicon
21 * cache we won't do anything unless aForceReload is true, in which case
22 * we'll try to reload the favicon.
23 *
24 * This function will only save favicons for pages that are already stored in
25 * the database, like visited pages or bookmarks. For any other URIs, it
26 * will succeed but do nothing. This function will also ignore the error
27 * page favicon URI (see FAVICON_ERRORPAGE_URL below).
28 *
29 * Icons that fail to load will automatically be added to the failed favicon
30 * cache, and this function will not save favicons for non-bookmarked URIs
31 * when history is disabled.
32 *
33 * @note This function is identical to
34 * nsIFaviconService::setAndLoadFaviconForPage.
35 *
36 * @param aPageURI
37 * URI of the page whose favicon is being set.
38 * @param aFaviconURI
39 * URI of the favicon to associate with the page.
40 * @param aForceReload
41 * If aForceReload is false, we try to reload the favicon only if we
42 * don't have it or it has expired from the cache. Setting
43 * aForceReload to true causes us to reload the favicon even if we
44 * have a usable copy.
45 * @param aFaviconLoadType
46 * Set to FAVICON_LOAD_PRIVATE if the favicon is loaded from a private
47 * browsing window. Set to FAVICON_LOAD_NON_PRIVATE otherwise.
48 * @param aCallback
49 * Once we're done setting and/or fetching the favicon, we invoke this
50 * callback.
51 *
52 * @see nsIFaviconDataCallback in nsIFaviconService.idl.

61 * Sets the data for a given favicon URI either by replacing existing data in
62 * the database or taking the place of otherwise fetched icon data when
63 * calling setAndFetchFaviconForPage later.
64 *
65 * Favicon data for favicon URIs that are not associated with a page URI via
66 * setAndFetchFaviconForPage will be stored in memory, but may be expired at
67 * any time, so you should make an effort to associate favicon URIs with page
68 * URIs as soon as possible.
69 *
70 * It's better to not use this function for chrome: icon URIs since you can
71 * reference the chrome image yourself. getFaviconLinkForIcon/Page will ignore
72 * any associated data if the favicon URI is "chrome:" and just return the
73 * same chrome URI.
74 *
75 * This function does NOT send out notifications that the data has changed.
76 * Pages using this favicons that are visible in history or bookmarks views
77 * will keep the old icon until they have been refreshed by other means.
78 *
79 * This function tries to optimize the favicon size, if it is bigger
80 * than a defined limit we will try to convert it to a 16x16 png image.
81 * If the conversion fails and favicon is still bigger than our max accepted
82 * size it won't be saved.
83 *
84 * @param aFaviconURI
85 * URI of the favicon whose data is being set.
86 * @param aData
87 * Binary contents of the favicon to save
88 * @param aDataLength
89 * Length of binary data
90 * @param aMimeType
91 * MIME type of the data to store. This is important so that we know
92 * what to report when the favicon is used. You should always set this
93 * param unless you are clearing an icon.
94 * @param aExpiration
95 * Time in microseconds since the epoch when this favicon expires.
96 * Until this time, we won't try to load it again.
97 * @throws NS_ERROR_FAILURE
98 * Thrown if the favicon is overbloated and won't be saved to the db.
