Prefilled website url and login data in

Always if i open website, there is a pre-filled url, which should be tested, and pre-filled login data in the tab “Auth” - and the test starts immediately.

To test a site a want to test, i’m forced to very quickly click at “reload page” and then “stop” in browser. After these actions i’m only able to delete pre-filled url, fill my own and start the test. Very annoying.

This happens only in Chrome (multiple versions) and at any login status into website.

What is this of the bad magic? Where is this coming from? How can i get rid of this?

PS: Firefox isn’t affected, at any login status.
