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. |
| Waterfox 6.6.6 Dec 9, 2025 |
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 |

| Waterfox 6.6.4 Oct 9, 2025 |
Theming: Resolved a long‑standing issue where Waterfox's styles could “leak” into the web page area. Customisations now apply only to the browser interface, not to website content. Improved handling of theme colouring to prevent contrast issues. Active tab context line has been enabled by default, after many requests. Tab groups: Smoother startup: automatic grouping now waits until your previous session has fully restored. It only applies to tabs you open after everything is loaded. Your existing tab order and groups are preserved at startup; nothing gets rearranged automatically. If you collapse your only tab group, you’ll still have a single ungrouped tab available. That tab won’t be pulled back into a group unless you choose to do so. Compatibility: Updated emoji support to Emoji 16.0.1 on platforms that don’t provide these characters natively, improving how newer emojis appear. |
