Waterfox Privacy Notice


  • Speed up your computer

    Every computer program you run takes up some memory. When too much is used, your system can slooooowww down. Waterfox aims for a balance — using enough memory to let you browse smoothly and leaving plenty of memory to keep your computer responsive.

  • Stop running out of memory

    Chrome uses up to 1.77x more memory than Waterfox. If your computer is already low on memory, this can cause a significant slowdown. Using Waterfox’s latest version with multi-process can result in more available memory to run your favorite programs.

  • Browse faster, privately

    Explore the web faster with Waterfox Private Browsing. Only Waterfox’s private mode includes tracking protection which blocks ads with trackers from loading on pages. Decluttering sites means web pages can load faster.

More privacy

Waterfox doesn’t sell access to your personal information like other companies. From privacy tools to tracking protection, you’re in charge of who sees what.
