Microsoft has patched the InPrivate Browsing Leakage bug in its newest Edge browser with Microsoft’s latest update. In private mode of the Edge browser is leaking users’ web browsing data. It has been found storing your browsing history, cookies and cache in a WebCache file on the system, which could be found easily. Microsoft has officially claimed that its Edge Browser is much more secure than any other browsers and does not need the support of any armour like EMET anymore. The issue made users feel a repulsive force again and they instantly switched back to other browsers like Firefox or Chrome.
