| Waterfox 6.6.8 Jan 12, 2026 |
This release adds manual tab unloading (useful for freeing memory without closing tabs) and improves how unloaded tabs are represented, fixes a few import/UI issues, and includes platform specific improvements for macOS and Windows. General: When importing data from another browser, empty profiles no longer appear in the selection list. Added an Unload Tab option to the tab context menu to free memory without closing the tab. Unloaded tabs now show a wireframe preview (after the tab has been active at least once). Fixed an issue where the Show duplicate tab menu item option did nothing on the Settings page. Updated search engine aliases so they no longer take over single-character shortcuts, allowing you to assign them as you wish: Google: @g ??' @go Bing: @b ??' @bi Ecosia: @e ??' @ec Mojeek: @m ??' @mo Qwant: @q ??' @qw Waterfox Private Search: @w ??' @wps JPEG XL images should look better (thanks to @goodusername123): The decoder now uses a higher quality blue noise dithering pattern to cut down on visible banding, and its upscaling step clamps overshoot to avoid haloing when enlarging images. Color handling is more reliable; improved ICC/CMYK processing means images with embedded color profiles should match their intended colors more consistently. General JPEG XL stability/performance tweaks from the upstream library: tighter buffering and math paths that should make decoding a bit smoother and less crash-prone. Security fixes for MFSA 2026-03 Windows builds now come bundled with the required Visual Studio redistributable files, meaning Waterfox will run on a fresh Windows install even if no other programs have been installed yet. Removed the survey checkbox from the uninstaller. |

Firefox import fix: Fixed an issue that prevented importing Firefox data on Windows. Even if you have already setup Waterfox, you can still import your data via Settings (about:preferences) ??' General ??' Import browser data. |

Various fixes: Private Tab will now use your default selected private search. The context menu search while in private tab will also open a new private tab instead of normal tab. Fixed an issue where the Bookmarks widget in the status bar would not open submenus, so now all bookmark folders now work correctly when the button is pinned to the status bar. Fixed a minor issue where the “Status Bar” entry in the Toolbars menu would output internal errors to the browser console. Cookie banner handling no longer logs spurious errors when browsing localhost, IP addresses, or other internal hosts; in those cases Waterfox now silently falls back to the global setting. Security fixes in MFSA-2025-94 Region & Geo Detection: What was happening: Firefox’s Region subsystem could still make a one‑time request to Mozilla’s privacy‑preserving geo‑IP service to infer your country on first run. That inferred “home region” is used by multiple subsystems (search, DoH rollout, feature gating, telemetry). The backend is designed to be privacy‑sensitive and only runs once, but it was still an unnecessary external connection we’d rather avoid. What we’ve changed: Disabled network‑based region lookup The URL used for region detection (browser.region.network.url) is now empty and locked. Wi‑Fi–based region hints (browser.region.network.scan) was already disabled but is now locked as well. Fixed, non‑dynamic “home region” browser.search.region is now set to a fixed value (US) and locked. This prevents any background attempts to “correct” or update your region based on IP. Why this matters: No calls are made to Mozilla’s region/geo‑IP services for normal browsing and features that still look at region see a stable, non‑changing value instead of one inferred from your network. AI & Machine Learning: What was happening: None of the Firefox AI features or settings (AI link previews, chat integrations, etc.) were enabled in Waterfox, and no AI processin |
