I learned a lot tonight. This is what dev tools tells me in Edge by just visiting eBay. The website is port scanning my laptop, bypassing my firewall, and doing it in/from the browser. It checked 14 ports. Let's discuss. 1/5

Bei Vodafone Deutschland den Handyvertrag fristgerecht kündigt und ein vermeintlich gutes neues Angebot am Telefon bekommen. Das was am Telefon erzählt wurde, wurde nicht eingehalten. Nach Widerruf wird auf den alten Vertrag mit neuer 24 monatiger Laufzeit zurückgestellt. #abzocke
