📝 What’s new in Waterfox 56.2.13?

  • Updated Gecko Media Plugin components
    • Waterfox now supports the latest version of the Widevine CDM (v10). This should last for a while until Google sunsets this version.
    • A few memory leaks were fixed due to this upgrade
  • Upgraded from Widevine CDM to Widevine CDM 4.10.1440.19
  • Upgraded from OpenH264 1.6 to OpenH264 1.8.1
    • This should result in less crashing and better performance
  • Support filtering streaming response data via webRequest API (Thanks to hawkeye116477)
  • Support access keys in extension menus (Thanks to ChiaYen Kan)
  • User agent overrides are now much easier to add - with the options to have an automatic updating list depending on how users feel about this.


  • If upgrading from previous versions of Waterfox, you will be asked to re-enable DRM. After re-enabling, if videos with DRM do not work please restart Waterfox and videos should start to work again.
