Waterfox combines a Mozilla browser base with your own operation and privacy choices. You can organize tabs horizontally or vertically and use relationships between tabs as a tree in the vertical view. This allows you to keep different topics together.

The browser has its own styles and a built-in content blocker. So you don't have to look for a loose extension for every adjustment. Waterfox is maintained by BrowserWorks and follows its own version series. The current desktop version is different from old Waterfox Classic downloads.

Compare Waterfox with alternatives

If you want to switch within the Firefox family, look at the default settings in addition to extensions. Some variants focus on privacy, others on vertical tabs or more setting options. Importing bookmarks doesn't automatically mean that all your settings and saved sessions will go along.

Who is it for?

You often have many tabs open and want more influence on their layout, without leaving the Mozilla browser base.

Getting started

Download the current desktop release for your processor and system. Import your bookmarks, choose a tab format and check your main websites and extensions.

Privacy

Waterfox focuses on limiting telemetry and has built-in blocking. A search engine, website or enabled synchronization service still processes data according to its own settings and conditions.

Good to know

Windows, macOS, Linux and Android do not always have the same features or version numbers. This page describes the desktop version.

Please note

Use the current desktop release and check the processor requirements. Install old extensions only when they are suitable for your version; support for classic extensions does not mean that any old extension will continue to work properly.

Advantages

  • You can order tabs as tree structures.
  • You can choose from different styles and tab layouts.
  • You get built-in ad and tracker blocking.

Things to consider

  • Extended tab settings ask for familiarity.
  • Extensions may react differently to your own browser adjustments.
  • The Intel/AMD release requires a processor with SSE4.2.

Our verdict

Waterfox especially has something to add when you work a lot with tabs and want to adjust their layout. A tree structure can help in researching or comparing products, because you see which pages belong to the same subject. If you usually use three tabs, that extra control is less decisive.

Check your important extensions and try a few real work sessions before switching completely. Choose one clear tab layout instead of changing all the options at once. Keep track of updates and use the modern Waterfox edition; old Classic versions are not an equivalent alternative to the current browser.
