Waterfox bygger på samma kod som Mozillas Firefox med den skillnaden att i Waterfox ingår enbart 64-bitars kods.
Waterfox, based on the Mozilla platform but created exclusively for 64-bit systems, has one goal in mind: speed. The only thing you may need to consider is that your plug-ins must be 64-bit, also.
Features
- Built with Clang-cl on Windows
- No Adobe DRM
- No Pocket
- No data collection
- Run every 64-bit plugin
- Run every add-on (even unsigned ones!)
- Windows XP 64-bit support
Note: While the software is classified as free, it is actually donationware. Please consider making a donation to help support development.
What’s new in version 140.8.0
Security
- Fixed multiple security vulnerabilities as described in Mozilla Foundation Security Advisory 2026-15.
- Fixed 3 CVEs in the JPEG-XL image decoder.
Bug Fixes
- Certificate reliability improvements: Fixed an issue that could cause “Unknown Issuer” certificate errors on certain sites, most commonly on Linux. Waterfox now refreshes intermediate certificate data as needed to keep HTTPS sites loading securely. No browsing data is collected but Waterfox may contact Mozilla’s certificate update endpoints to fetch missing intermediate certificates and revocation data.
Stability
- Printer driver isolation (Windows): Printer drivers are now loaded in a separate process, preventing buggy drivers from crashing Waterfox. This uses Windows’ application-level printer driver isolation to keep third-party driver issues from bringing down the browser.
Performance
- Small performance improvement in JPEG-XL image decoding (improved LUT loading and added RGB offset dithering).
Experimental
- Ogg Theora support can be re-enabled by setting media.theora.enabled to true in about:config.
