Some users around the forums are seeing issues with NPWM, and other extensions with Edge, Chrome and other browsers. This article speaks about how Edge extension performance detector is causing issues with the way some extensions process extra code and customizations for users. Microsoft Edge’s browser essentials feature is where this can be found. It can be disabled in the same manner as enabling per the article.
No such option as “Extension Performance Detector” when searching “edge://flags/” on the latest version of Edge. Does not solve the problem with NPWM on Edge.
The posted article states MS is “testing” this as it hasn’t been released publicly. It will be rolled out when Edge version 130 releases and can be found in Edge Browser Essentials. The current version of Edge is Version 129.0.2792.52 . This post was informative in nature.
What is your issue with NPWM and what version Norton do you have installed?
