Pale Moon (64bit)25.3.0

Pale Moon is an Open Source, Firefox-based web browser for Microsoft Windows, focusing on efficiency and ease of use. Make sure to get the most out of your browser!

Pale Moon offers you a browsing experience in a browser completely built from source with carefully selected features and optimizations to maximize the browser's speed*, stability and user experience, while maintaining compatibility with the thousands of Firefox extensions you have come to love and rely on.

This browser, even though close to Firefox in the way it works, offers a different set of features than its sibling. A few carefully selected features have been disabled that are not in high demand, and that do not interfere with the way web pages are displayed or function; all to maximize the efficiency of the browser. Please see the page with technical details to learn exactly what the browser supports, and what it doesn't support. For example, if you need accessibility features or parental controls, then please visit the Firefox homepage and get the official, non-optimized version of the browser.

Pale Moon will continue to provide appropriately sized grouped navigation buttons, bookmark toolbars enabled by default, tabs next to the default page content (easy to switch) and at least no functional status bar and more freedom of customization, to name a few things.

Pale Moon is and will always be open source and completely free to download and use!

What's New

Version 25.3.0

  • Overhauled WebGL. It now properly supports depth textures, shadow mapping and glow shaders.
  • Note that older operating systems or older/embedded video processors may be limited in their support of these features.
  • Updated the ANGLE library to a much more current version.
  • Removed the crash reporter code completely to improve overall browser responsiveness and operation.
  • Please note that a necessary victim of this has been the in-browser (devtools) SPS profiler because of its reliance on crash reporter data-gathering tools.
  • Removed the Mozilla Plugin Finder Service (no longer in use @Mozilla).
  • Android: removed the Mozilla "product announcements" service.
  • Re-added control of the number of concurrent tabs to be restored from a session with browser.sessionstore.max_concurrent_tabs (accepted values 1-10)
  • Significantly improved performance and accuracy of date/time/timer handling.
  • Significantly improved performance of the creation of DOM elements with plain text content.
  • Added several significant performance optimizations for arrays and strings in javascript.
  • Added several code performance optimizations and bugfixes in SVG, the presentation shell, SCTP, style gradients and CSS parsing routines. (Thanks, Axiomatic!)
  • Added an "Open link in current tab" context menu entry on links for UI consistency.
  • Updated styling of the browser with personas (lightweight themes) once more to improve display in tabs-on-top mode, improve overall legibility of tab text, and display of inverted close buttons on some controls on dark personas.
  • Added a special case check for the Flash plugin version check on Linux failing due to commas instead of periods in the version string.
  • Added Windows 10 compatibility in executable manifests.
  • Android: Fixed a crash on GL canvas surfaces.
  • Fixed incorrect Sync "howto" instruction links from the Sync dialogs.
  • Fixed the color of selected tabs in Linux when personas (lightweight themes) are in use that do not match the overall tone of the OS system theme.
  • Fixed a bug where a variable in parentheses would abort Javascript parsing.
  • Fixed a bug where the address bar would incorrectly be cleared.
  • Fixed padding issues for dropdown lists.
  • Fixed DNS lookups so proper record types are requested for IPv4 and IPv6.
