What features does Waterfox currently have?

  • Disabled Encrypted Media Extensions (EME)
  • Disabled Web Runtime (deprecated as of 2015)
  • Removed Pocket completely
  • Removed all telemetry/data collection being sent back to Mozilla
  • Disabled the 64-Bit NPAPI white-list so that the user can decide what plugins they can run (doesn’t make sense for Mozilla to do this as most of their user base probably aren’t technically proficient), but it’s something Waterfox users are capable of handling.
  • I’ve also allowed unsigned extensions to run as well as there are still some old extensions people like to use (it’s disabled by Mozilla for the same reason as above)
  • Windows XP 64-Bit support
  • ICU updated to 57.1
  • Removal of Sponsored Tiles on New Tab Page


  • When using a profile shared by Firefox, sponsored tile and snippet URLs may overwrite default Waterfox settings, enabling them again
  • Automatic updates will be delayed by 24 hours to make sure there aren’t any pressing issues before seeding to everyone.
