Any update on this?

The issue is most reliably reproduced for me when I'm using the advanced view. Local Storage associated with cookies that are not Favorites is not reliably deleted. I've switched off the advanced view and things seem to work better.

No movement on this? It's been over a month since I raised this. This flaw makes Cookie less than useful.

Yes, I'm sure these are not databases that are being regenerated by Safari upon launch. First, the problem exists in Safari, Chrome and Edge. Second, the databases that are retained are for random sites I've visited that are not in my favorites or would be pre-fetched by any browser for any reason.

I may have spoken too soon. Even using the simple interface certain Safari caches are not deleted.

It seems that this does work as expected (i.e., localstorage databases are deleted) if the simple cookie user interface is selected, but localstorage databases are not deleted if the advanced interface is selected (no matter what deletion options are selected).

yes, they are still displayed after a browser restart. A good example is NYPost.com, for which Safari and Chrome continue to indicate a local storage entry even after a browser restart and a system restart. I'm using MacOS 10.15.4 and updated browsers -- and the Mac App Store version of Cookie.

I have cookie set to delete everything, and all cookies are being deleted (except favorites) -- but when I check in Chrome or Safari website localstorage items remain and can only be deleted through the browser's options. Any thoughts about this?
