I just installed Cookie on a new Mac computer.
It is leaving a lot of items labeled as Cache - as seen in the privacy tab of safari
over 400 lines of items with check marks are listed and greyed out. The items are web sites from long ago.
I've tried uninstalling/reinstalling Cookie without result. I have not yet tried to restart the computer - and cannot until the new online backup completes.
full removal of Cache requires a restart of your browser. And the grey out websites sounds like you may be syncing your favourites to your browser bookmarks?
If this is not the case, then you can easily
un-favoritemultiple domains by
shift/command-clickingmultiple domains and using the context menu to
un-selectthem all at once.
You open the context menu by
control-clickingon the cookie domain table
