I can see option to manage (enable/disable/uninstall) browser plugins for chrome/internet explorer/ firefox but not seeing tab for edge browser.
There are usually listed umder Internet Explorer still.
However note that Edge browser is Chromium based, so the extensions/plugins for Edge are basically Chrome extensions.
if you have added extensions/plugins to Edge then some of them may show up as being Chrome extensions.
I’m not seeing edge extentions neither in Internet explorer/chrome plugins section !! some this is not working right for edge extensions, it works firefox and chrome.
