In a completely new firefox profile in settings, under "Sync", the option of "Firefox Labs" are present. But after applying user.js it is gone. How can i enable it?
Before using user.js

After using user.js

Ive tried reading through the user prefs changed in the user.js, but i couldn't find anything related to experimental or labs that when changed, would make Firefox labs reappear(although i did not try to disable/enable EVERYTHING)
