Is there a way to save the complete Edge settings, not just only the "Favorites sites" that I know I can export and import? So that I can try to revert to default settings (to check if some malfunctions are due to some settings) and, then, go back to my "saved" settings
no. best way to transfer is idd sync with profile. even moving the profile folder you will lose any password and extensions.
Very interesting. I don't know of any settings or anything else that can't be backed up and restored later. If you would be so kind and write what are these that can't and why.
