Hi DS. I'm Greg, an installation specialist, 10 year Windows MVP, and Guardian Moderator here to help you.
Unfortunately S mode won't allow any apps other than ones you install from the Microsoft Store app, so to use other browsers you'd need to get out of S mode following these steps:

Then install Google Chrome from here:

I would have several browsers on your task bar so there's always one that's best for the task. I use Firefox, Edge and Chrome in that order of preference. It's easy to share bookmarks between all of them in their settings under Import Favorites from another Browser, and Firefox and Chrome let you sign in to sync your Favorites on any other device you sign into. Set the preferred browser as Default in Settings > Apps > Default Apps.
Edge is being rebuilt on the Chrome chassis and will be re-released soon:

If you want to preview the new Edge Browser you can join the Edge Insider program and even interact with developers: https://www.microsoftedgeinsider.com/en-us/?for...
I hope this helps. Feel free to ask back any questions and keep me posted. I will keep working with you until it's resolved.
