Edge doesn’t support “noframemerging” feature. We have an application with use cases that require having multiple login sessions open at the same time. These sessions are merging when opened in different InPrivate Edge windows, as cookies are shared among all open InPrivate windows. With Edge’s multiple profiles feature, this issue is mitigated but not entirely for some of our use cases. Is there a plan to bring back the support of “noframemerging” or anything to that effect in future versions of Edge? Also, in case it matters, our application needs to run in IE mode in Edge so any alternate feature would need to work for this case as well.
@Darshini_Patel Thanks for letting us know that you'd like to see "noframemerging." I'm looping in one of our product team members and will let you know if they have any clarifying questions or insights on this.
