Hi UmmLila,
Greg wrote this on another post a while ago. Could you perhaps try this and see if it works?
If you would like to continue using Safari with the collector
you need to disable a new feature that they added recently. If you go to
the preferences panel, select "Privacy" and uncheck "disable cross site
tracking".
Cross site tracking is what allows one site to leave a cookie that
another site can use. This is how YLF knows you are logged in when you
are on the Nordstrom page. I'm afraid that's the only way it can work
right now.
Of course, some people are worried about cross site tracking's
privacy implications. Many things on the web depend on it though. Mostly
ad providers who want to target you with relevant ads. Also sites like
Facebook, who can track when you go from their site to another website
that uses some other kind of FB widget.
Normally with this sort of thing Safari would allow you to specify
certain sites where you want to allow tracking, but that doesn't seem to
be the case right now.
For an in between option, you can check the "ask websites not to
track me" option. That will stop legitimate ad providers (and Facebook)
from doing cross site tracking and serving you relevant ads, but it
won't stop YLF's collector (which is not "tracking") or someone who
ignores the request not to track.
