I don't know how it happen but all of the extensions in my Firefox Developer Edition have been merged/imported into my original Firefox app. Can someone explain why and how to fix it?

Do you use Firefox Sync to share data between your various installations/profiles of Firefox? You can include or exclude extensions from Sync. https://support.mozilla.org/kb/how-do-i-choose-what-types-information-sync-firefox

I just now realized that i have signed in on firefox developer edition and that must have caused this issue. I didn't know that extensions are synced. Thank you for your reply!
