I'm using cookie 6 app store version and notice that HSTS cookies are not being deleted for non-favourites. I have removal set to delete the caches on Safari &/or Cookie quit. The scripts are in place.

The cache removal script 11/04/19 is:
usr/bin/killall -KILL nsurlstoraged
find /private/var/folders ! -name "SafariTechnologyPreview" -name "com.apple.Safari"
-exec rm -r {} ; 2>/dev/null

Not sure why there needs to be a separate script but I seem to have aquired a Safari TP cache script 28/03/19 (there's another forSafari TP history):

/usr/bin/killall -KILL nsurlstoraged
find /private/var/folders -name "SafariTechnologyPreview" -exec rm -r {} ; 2>/dev/null

No scripts are needed for Firefox

OK thanks Russell

Do we need Scripts for Firefox and if so, where weould I find them.

Thank you for the response.

I'm not sure which they are but - most likely cached cookies. Since a quit and restart Safari "apparently" eliminates all those cookies that are not set as favourites in Cookie, it sounds as though that is what is happening.  Cookie does delete them but it's not reflected in Safari until it's done a restart.  If that is the case then I think Cookie is probably working as intended.

In the past Cookie would show in red those cookies marked as tracking ones.  Now it simply lists that there are X number tracking cookies.  It would be good if the old behaviour could return.

For some time I've been unsure whether Cookie (app store version) is succesfully deleting cookies and clearing caches, so I've been trying to use them by pasting them in Terminal and then check Safari -> prefs  -> privacy -> manage website data to see if they've gone

I'm running as user and cookie has permissions System rw, wheel read only, everyone read only. The scripts are in ~/library/application scripts/com.sweetpproductions.Cookie5

The machine is running Sierra 10.12.6: Safari 11.0.2 (12604.4.7.1.6)

The script pasted in terminal is: 
#!/bin/sh
/usr/bin/killall -KILL nsurlstoraged

Google and some other cookies remain (though not listed in Cookie) although only I only have a current connection to the Sweetpproduction site.

What's going on?

Despite setting Cookie to remove cookies on a timed basis (and on quit), I continually found cookies listed in Firefox (using FF prefs) that should have been removed.

I couldn't figure out why so I deleted Cookie and then reinstalled from the App Store.  Now no cookies are appearing in Cookies list - favourite or otherwise - and the app doesn't appear to be doing anything.  There are still a shed load of cookies listed under Ffox prefs.

What's going on?  I suspect it may be something to do with sandboxing as I run in a user account.

One other point.  Where is the file to import previous favourites?  The reinstall 'knows' there is one but I can't find it.

yeah Cache cookies aren't parsed by Cookie. they are removed if you enable cache removal - although Safari needs to be restarted to display any cache removals.

That may be what's happening.  Using Safari, I've unchecked cache removal and the site now appears in the list of sites but still no cookie in the list.

Couple of questions:

I think cache removal needs to be checked/enabled to purge ever-cookies, although if I identify it as a favourite will it overide this?

Will the same apply with Ffox?

The above would mean that for the first few times I use Cookie, I would need to disable cache removal in order to identify any favourites.  EG those containing login details for forums and stuff.

what are your Privacy settings in Safari?
are you running in Private Browsing mode?

Privacy:   Allow cookies from websites I visit

Not in private browsing mode

Interesting looking at Safari.  Some of the stuff is labelled 'cache' but these are not listed in Cookie.

For a fresh install you need to delete the folder:
~/Library/Containers/com.sweetpproductions.Cookie5

OK done all that with a fresh install within my user account with admin privileges, so I should have the correct permissions.  Currently these are

user:  R+W
admin:  read only
everyone:  read only

I  then visited  http://forums.thinkbroadband.com/threads.php  This should set a cookie since it needs it to remember login details.  There are also ads from Doubleclick on the site so there will probably be a tracker.  Nothing shows in Cookie although one does show up as forums.thinkbroadband.com  Another one is from Sweetpproductions and that doesn't show in Cookie, but does in Ffox.

Either Cookie is blocking all non-favourites or it's not doing anything - at present I'm not sure which it is.

are the missing cookies cache cookies? if so, Cookie doesn't display them - but does remove them with the cache.

TBH I wouldn't know where to look for cache cookies

In the past any cookies set would display in Cookie so I could make them favourites (or not).  Now they don't display but they are listed in either Ffox or Safari prefs.  Any site with trackers used to show the number of trackers in red, something that no longer happens.

Let me know where the appropriate logs are and I'll see what I can do.  Something changed around the 5.4 update which is why I tried to delete everything and start afresh.
