I want import and export functions for setting items

I am very nervous.So check your settings often.
and,I’m worried about initializing the settings and resetting them.As with firefox, many major browsers do not have the ability to import and export settings.
However, it is implemented in some chromium browsers.
I don’t use bookmarks much because I use a bookmark app because I use html files when synchronizing with my PC.
So, how about importing and exporting settings in the form of remembering the settings in the account with any operation?
