You can stop this by changing the settings in your browser. In Firefox go to about:config and search for browser.navigation.requireUserInteraction and toggle it so that it says true.

Go to about:config and set “browser.navigation.requireUserInteraction” to true

Go to about:config and set “browser.navigation.requireUserInteraction” to true

You shouldn’t give out your real email address. I instead use randomly generated email addresses that forwards emails to my real one. I can easily deactivate any forwarding email address and therefore stop any unwanted emails.

It works really well and also has other benefits like for example knowing who sold your information if you start receiving spam.

You also gain a bit of privacy and security from being a tiny bit harder to track and your credentials being less valuable in the case that the company you gave the random address to has a data breach.

This video explains the concept very well.
