The difference between the two security features is that Safe Browsing will compare a visited site to a locally stored list of domains, compared to Enhanced Safe Browser, which will check if a site is malicious in real-time against Google’s cloud services.
While it may seem like Enhanced Safe Browsing is the better way to go, there is a slight trade-off in privacy, as Chrome and Gmail will share URLs with Google to check if they are malicious and temporarily associate this information with your signed-in Google account.
I forwarded all my gmail addresses to proton recently. I’m very pleased! It works a lot better than gmail-to-gmail forwarding and the UI is purple! Purple!!
Proton has been great and I recently found out that I get free access to simplelogin.io for email masking with my proton account.
