If you have use the one in windows 10/11 its a bit of a nightmare. You have to manually change the default browser for all file types from edge to your new browser. And there are about 20 options you have to manually change over.
Edge does a lot of things to annoy me on Windows, but this is not one. I do not think I had to change the default browser for every file type. Also the normal user would never notice this problem, as they rarely open HTML files directly.
In 11 changing the default browser does not change all the filetypes the broswer can open. Setting an alternate browser as the default only sets the new browser to open a few filetypes. Its why I see confused illiterates at my workplace with Chrome, Adobe, and Edge open.
What browser do you suggest for illustrator files? You photoshop directly in firefox? Adobe applications are a necessary evil for some people, and multiple browsers can be handy for sandboxing or separating user profiles, especially on public machines. People with multiple applications open aren't "confused illiterates" jfc. They just use their computers differently from you.
The latest trick is they ignore the default choice completely and open all links in Outlook in edge anyhow, also they are sending notifications saying to use edge or get less battery time.
The idea is it gives enough time for competition to establish and then everyone completes on an even footing without fettering the original monopoly after it's no longer a monopoly in that space... arguably it worked as Chrome took over but all that's happened it it made a new monopoly 🤷🏻♂️
