Just an FYI: I'm not seeing any leftover HSTS Policy entries (or other non-favorites) in Safari-Preferences-Privacy-Manage Website Data with Safari 12.1 and High Sierra 10.3.6/Security Update 2019-002.

Things seem to be working as expected so far with Safari 12.1 and Cookie 5.9.6 (MAS) on High Sierra 10.3.6/Security Update 2019-002

@kitated said in Safe to update to Safari 12.1 with Cookie (MAS) 5.9.6?:

It's working fine for me except I've noticed that some HSTS policy cookies are not being deleted when the cache is removed. I've started a separate thread for this.

Thanks for the info.
I'm on High Sierra-I think I will go ahead and update and report back.

Any known issues

Still hoping for Cookie to let us manage each Firefox profile separately, like it does for Chrome.

Well, clearing the cache (and everything else) using Chrome's "Clear Browsing Data" command does not reset the "Use a prediction service to load pages more quickly" preference. So, it seems that Cookie might be doing something to cause this.

@SweetP said in Safari 12.x default blue webiste icon permanently removed by Cookie?:

Are you certain the issue you are seeing is Cookie related? maybe it was removed from Safari in an update?

I think that starting with Safari 12 that the default website icon now lives somewhere in /Users/Library/Safari/Favicon Cache.
Cookie5 (MAS) nukes this entire folder when 'Favicons' are removed...

Do the recently updated CookieScripts address this issue?

The icon shown at the left of the Safari URL bar when the website does not have a custom Favicon.

Seems like Cookie may have permanently removed the blue default from Safari 12.x URL bar on Sierra. Is this the intended behavior? Is there a way to get it back?
