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.

26 * Creates a RGB/RGBA texture (or uses one provided) and uploads the surface
27 * contents to it within aSrcRect.
28 *
29 * aSrcRect.x/y will be uploaded to 0/0 in the texture, and the size
30 * of the texture with be aSrcRect.width/height.
31 *
32 * If an existing texture is passed through aTexture, it is assumed it
33 * has already been initialised with glTexImage2D (or this function),
34 * and that its size is equal to or greater than aSrcRect + aDstPoint.
35 * You can alternatively set the overwrite flag to true and have a new
36 * texture memory block allocated.
37 *
38 * The aDstPoint parameter is ignored if no texture was provided
39 * or aOverwrite is true.
40 *
41 * \param aData Image data to upload.
42 * \param aDstRegion Region of texture to upload to.
43 * \param aTexture Texture to use, or 0 to have one created for you.
44 * \param aOverwrite Over an existing texture with a new one.
45 * \param aSrcPoint Offset into aSrc where the region's bound's
46 * TopLeft() sits.
47 * \param aPixelBuffer Pass true to upload texture data with an
48 * offset from the base data (generally for pixel buffer objects),
49 * otherwise textures are upload with an absolute pointer to the data.
50 * \param aTextureUnit, the texture unit used temporarily to upload the
51 * surface. This testure may be overridden, clients should not rely on
52 * the contents of this texture after this call or even on this
53 * texture unit being active.
54 * \return Surface format of this texture.
