Pale Moon
Pro VerifiedPale Moon is an open-source, Goanna-based desktop browser for users who value interface customization, classic extension support, independent development, zero vendor telemetry, and a traditional single-process browsing design.
Independent Goanna Browser for Desktop
Pale Moon is an independently developed web browser built on the Unified XUL Platform and its Goanna rendering engine, which originated from older Mozilla technology but now follows a separate development path. The browser emphasizes desktop customization through complete themes, XUL extensions, configurable toolbars, familiar bookmarks, profiles, history, downloads, passwords, and tab controls. It contains no vendor telemetry, sponsored content, DRM module, or integrated AI features, and its default services are selected independently of major commercial browser platforms. Users can install language packs, search plugins, and project-specific add-ons from its own ecosystem. Its traditional interface and single-process architecture distinguish it from current Chromium and Firefox releases during everyday desktop use.
Pale Moon 34.3.2 is the current Windows release and delivers security fixes, stricter media validation, font-parsing corrections, NSS updates, and minor web-compatibility improvements. The verified 34.7 MB x64 installer requires Windows 7 SP1 or later and a processor with AVX support, while official 32-bit builds support older processors. Users who prefer external credential management can evaluate Bitwarden separately, but extension compatibility should be confirmed before relying on browser integration. The independent Goanna engine implements a deliberate selection of mature web standards, so some Chromium-focused sites or newer web applications may not work exactly as expected. Keep the browser updated and retain a maintained secondary browser for incompatible services that must work reliably.

Frequently Asked Questions About Pale Moon
Yes. Pale Moon is open-source software distributed under the Mozilla Public License 2.0, and users can download official desktop builds without paying a license fee. Its source code is available through the project’s developer resources, allowing inspection and community contributions within the license terms. Free use does not mean every branded build may be redistributed without conditions, because the project separately protects its name, logos, and official binaries. For normal installation, obtain the package carefully from the project’s download page or one of its listed mirrors. That approach reduces the risk of modified installers and gives you access to published signatures and checksums for verification.
It minimizes browser-vendor data collection, but it does not make web activity anonymous. The project states that the browser contains no telemetry, advertising, data gathering, or integrated cloud features designed to profile usage. However, websites, search providers, internet service providers, extensions, and network administrators can still receive information generated during normal browsing. Private windows mainly limit local history and session storage; they do not conceal your network address from sites or providers. Review the configured search engine, cookies, permissions, extensions, and synchronization choices according to your needs. For stronger anonymity or traffic routing, use a purpose-built tool and understand its limitations before relying on it.
It supports its own XUL-oriented add-on ecosystem and many legacy Firefox extensions, but current Firefox or Chrome extensions are not automatically compatible. The browser exposes lower-level extension interfaces and supports complete themes, lightweight themes, language packs, and search plugins through project-specific catalogs. Check the add-ons site for a maintained version made for the current browser release before installing anything. An old extension may load yet still be unsafe, broken, or incompatible with newer websites. The browser also retains NPAPI plugin support, but obsolete plugins can create serious security and stability risks. Install only software you trust, remove unused components, and retest add-ons after each browser update.
Pale Moon can struggle with sites that assume Chromium-specific behavior or depend on web technologies its independent engine has not implemented. Goanna and UXP follow a separate development path, so their standards support, JavaScript behavior, media handling, and layout results are not identical to Chromium or current Firefox. A failure does not necessarily mean the browser is outdated; it may reflect a deliberate feature choice or an application that tests only dominant engines. Update to the newest release, retry with problematic extensions disabled, and test a clean profile when diagnosing errors. If an essential banking, work, or streaming service remains incompatible, use a maintained secondary browser for that site.
Official Windows builds require Windows 7 SP1 or later. The regular 64-bit installer targets x64 systems and needs a processor with AVX support; the official 32-bit Windows build supports older processors. The supplied package baseline lists 2 GB of RAM, 1.5 GB of storage, and no dedicated graphics card requirement, although actual memory and disk use increase with open tabs, cached data, extensions, and profiles. Confirm that the operating system is fully patched and that enough free space remains for updates and temporary files. If the 64-bit program refuses to start on older hardware, verify AVX support or consider the maintained 32-bit build before installing it.
