I enabled "Cookies und Websitedaten beim Beenden von Chromium löschen" (Delete Cookies and Web Site Data when exiting Chromium).

Still, after quitting and restarting Chromium, the list of sites with stored Cookies and other information under "Alle Cookies und Websitedaten anzeigen" (Show all Cookies and Web Site Data) is huge.

I expect it to be empty after a restart, except for maybe some specific white-listed Cookies.

Do you have the "Preload pages for faster browsing and searching" option enabled (it is on by default)? This feature advertises that preloaded information can include cookies.

Also, is your previous browsing session being restored when you launch chromium? That would load all previously loaded pages, and thus most likely write cookies to disk.

No, I have not, it's disabled.

No, the browser window only shows the welcome page.

However I just checked it now after explicitly deleting cookies and
website data yesterday after reporting this.

I closed Chromium and restarted it. Currently, only cookies for
whitelisted domains seem to be stored, but I have "file system" data for
Amazon and several other domains listed - however, if I check details,
it says "0 bytes" for every entry I checked, so that's probably (?) ok.

So not sure how this huge list of cookies and all the other stuff ended
up in Chromium and was only deleted after manually requesting deletion
of the web site data.

This isn't necessarily even related to the snap migration, I think.

Indeed, that smells more like an upstream bug. Would you mind filing it at https://bugs.chromium.org/p/chromium/issues/list, and sharing the link to it here?
