Microsoft investigating claim that Edge’s private mode saves visited pages

Microsoft is investigating a report from a security researcher that the Windows 10 Edge browser saves pages visited when browsing in InPrivate mode. This would make it possible to find out which page a user has viewed in private mode.

Microsoft does not immediately confirm the problem, but does say that it “wants to solve this as soon as possible,” according to a statement the company gave to tech site The Verge. The site claims to have at least partially reproduced the problem and to have seen a page visited without specialist knowledge after the session was closed.

Its discoverer, Ashish Singh, wrote several months ago that Edge appears to be leaving several marks on InPrivate browsing. The point of that mode is precisely that there are no traces of it, so that the user can browse without having to worry about finding details on the PC.

Microsoft introduced Edge as the successor to Internet Explorer in Windows 10 last summer. Because Microsoft has not taken IE as a basis, the software maker is still working on adding functions to the browser. For example, from this year there should be support for extensions in Edge.
