After a recent update this extension now forces a cookie into the browser. If you delete this cookie the extension puts it back after browser restart. This will happen even if you're logged out of the Nord VPN extension. I emailed customer support their advice was to disable the extension if I didn't want the cookie. The cookie is called _cf_bm , it's a cloudflare cookie they say is for "bot management". We tested other VPN extensions and none of them did this. I wrote this review last week but my review seems to have been deleted. I'm not sure why Nord VPN have started to do this but a VPN extension should not be forcing a cookie in your browser.
