Pale Moon is a custom-built and speed optimized Firefox browser. The project uses contributed Open Source code to create a full-featured, speed optimized browser based on Firefox browser.

Having seen the advantages on other systems (e.g. Linux) with regards to programs being compiled specifically for the capabilities of the machine it is installed on, it became obviously clear that Windows users were at a disadvantage.

Mozilla only releases windows executables with maximum compatibility in mind, meaning that Firefox is made to run on as many different systems as possible, sacrificing efficiency and speed in the process to be compatible with, by current standards, absolutely ancient hardware.

Mozilla does not provide optimized browser packages for Windows. That means you may be lose speed and efficiency when you use your browser.

That needs to change. Therefore Pale Moon project offers custom-built and optimized Firefox browsers for Windows Operating Systems. Make sure to get the most speed and efficiency out of your browser!

Pale Moon Main features:

  • Highly optimized for modern processors
  • 100% Firefox sourced: As safe as the browser that has seen years of development.
  • Support for Firefox extensions (add-ons), themes and personas
  • Able to use existing Firefox profiles, bookmarks and settings with this migration tool
  • Uses slightly less memory because of disabled redundant and optional code
  • Significant speed increases for page drawing and script processing
  • Support for HTML5 and WebGL (v4)
  • Stability: experience fewer browser crashes.
  • Support for SVG and Canvas, and downloadable fonts including WOFF
  • Support for OOPP (Out-of-process plugin execution)

Users will find a slightly more conservative approach to changes in the user interface in the Pale Moon browser. It, although very close to Firefox, is (now more obviously so than before) a different product. However, these differences in layout do not prevent anyone from configuring their browser interface to exactly the way they want it to look and work. Including like Mozilla Firefox’s default layout if they so wish.

Changes in Pale Moon 32.2.0 (2023-05-16):

  • Implemented dynamic module imports. See implementation notes.
  • Implemented exporting of async functions in modules.
  • Implemented JavaScript class fields. See implementation notes.
  • Implemented logical assignment operators ||=, &&= and ??=.
  • Implemented a solution for websites using the officially deprecated ambiguous window.event. This is disabled by default but can be enabled through about:config’s dom.window.event.enabled preference. See implementation notes.
  • Implemented self.structuredClone() (this may be very obscure to anyone except web developers. Apologies 😉 )
  • Implemented Element.replaceChildren. Once again primarily a web developer note.
  • Improved Shadow DOM :host matching.
  • Implemented WebComponents’ CSS ::slotted() and related functionality.
  • Improved page caching in our memory allocator.
  • Added support for FFmpeg 6.0, especially important for bleeding-edge Linux distros.
  • Fixed a potential drawing deadlock for images, specifically SVG. This solves a number of hang-on-shutdown scenarios.
  • Fixed various crashes related to WebComponents and our recent JavaScript work.
  • Fixed various build-from-source issues on secondary target platforms.
  • Fixed various small browser front-end scripting issues that could lead to errors or broken functionality.
  • Fixed handling of async (arrow) functions declared inside constructors.
  • Fixed various small JavaScript conformance issues.
  • Fixed an issue where JavaScript (only in modules) would not properly create async wrappers.
  • Updated the DOM Performance API to the current spec (User Timing L3).
    See implementation notes, especially if you intend to use this in web content for critical functionality.
  • Updated keypress event handling to send keypress events on Ctrl+Enter.
  • Updated internal JavaScript structures to make future porting easier, as well as improve JavaScript performance.
  • Updated window handling and styling on Mac.
  • Updated the Freetype lib to 2.13.0.
  • Updated the Harfbuzz lib to 7.1.0.
  • Updated our DNS lookup calls to use inet_ntoa() instead of the deprecated inet_ntop().
  • Updated the Fetch API to use the global’s base URL instead of the entry document’s base URL for spec compliance.
  • We no longer support the outmoded fontconfig on GTK systems.
  • We no longer parse or return the body of known-empty responses from servers (content-length of 0, or in case of HEAD or CONNECT methods).
  • Implemented scaled font caching on GTK, improving performance.
  • Fixed a build issue when building for Linux on ARM64 on later distros.
  • Split out more parts of the browser into separate .dll files on Windows to reduce compiler strain and an oversized xul.dll
  • Removed mozilla::AlignedStorage (code cleanup).
  • Builds for FreeBSD now use xz for packaging instead of bzip2. By request, we now also offer GTK2 builds for FreeBSD.
  • Merged the preference dom.getRootNode.enabled into the dom.webcomponents.enabled pref. See implementation notes.
  • Fixed a potential DoS issue with JPEG decoding.
  • Fixed a potential issue in Windows widget code that could lead to crashes.
  • Disabled potentially hazardous external protocols on Windows.
  • Added known-problematic .dlls to the internal blocklist.
  • Security issues addressed: CVE-2023-32209, CVE-2023-32214 and several others that do not have a CVE designation.
  • UXP Mozilla security patch summary: 4 fixed, 1 rejected, 27 not applicable.

Changes in Pale Moon 32.1.1 (2023-04-18):

  • Fixed a crash in CompareDocumentPosition with Shadow DOM.
  • Fixed a crash with display:contents styling.
  • Added a preference to disable the TLS 1.3 protocol downgrade sentinel (see implementation notes).
  • Changed the way large clipboard copy/paste operations are handled, improving privacy (see implementation notes).
  • Improved filename safety when saving files to prevent potential environment leaks (bis).
  • Improved sanity checks of MIME type headers.
  • Security issues addressed: CVE-2023-29545 and CVE-2023-29539.
  • UXP Mozilla security patch summary: 2 fixed, 1 rejected, 49 not applicable.
