Problem setting Firefox as default browser

more options

The situation is like this: I once reinstalled Edge, and then Firefox disappeared from the default browser options in Windows settings. No matter what I do, I can't make it appear again and set it as default browser. I want to ask if there's any solution, apart from reinstalling the browser,because I have a lot of data in the browser and I'm afraid backing it up and transferring it won't be convenient.

Show that you have Firefox installed in the add / remove applications(appwiz.cpl from run window). Let me boot windows and see what your options are.  ;-/
