I made changes to my about:config that improve the privacy of my browser, but I realized that I want to keep the default settings in firefox developer edition as I do web development. Is there a way to export the about:config settings that I have modified to the normal version of firefox so that I can use it for personal stuff?

My Firefox version on the dev edition is 87.0b5 and 86.0 in the normal version.

The values of modified prefs are stored if prefs.js in the profile folder, but it is really not a good idea to transfer this file. You can possibly check the file in a text editor and copy lines that look important, but newer Firefox versions like DE have a lot of prefs that aren't compatible or are specific to this profile and release. You can also run into issues if you come to update the release profile at a later time from 86 to 87 and the profile needs to be migrated.
