The reason behind this is the follow creators feature that was added by Microsoft Edge in January 2022.
The bug was first noticed by a Reddit user known as hackermchackface last week.
The Redditorhackermchackfacewrote:
What is causing Edge to leak all visited URLs following latest update?
API is: bingapis.com/api/v7/followweb/isfollowable ?
GET request includes full url of every page navigate to.
Surely I cant be the first to discover this?
