Small Firefox config to disable most of the junk and slightly improve privacy and user experience
This is a very minimal config, so it should be compatible with all modern Firefox versions and is unlikely to get broken by updates.
😌 Want to achieve true peace of mind?
Consider using Zen Browser instead to save yourself headaches. All updates will be free from the junk, regardless of what Mozilla decides next.
