Microsoft is getting more aggressive in its attempts to push the Edge browser. In Windows 10 insider build 17744, whenever users try to install or open Firefox or Chome, they get a pop up reminding them Edge is already installed on their system. This feature isn't in mainstream builds of Windows yet, but seeing how the October 2018 update is just around the corner, it could be there soon. "You already have Microsoft Edge -the safer faster browser for Windows 10" and offers options to "open Microsoft Edge" and install anyway.
