Pale Moon 32.3.0 changelog:

This is a major development update, further improving web compatibility.


  • Added the (hidden) preference browser.history.menuMaxResults to allow users to control how many history entries are listed in the menu. Setting this to 0 will hide history menu entries altogether, and any positive number configures how many entries the entries are limited to. The default if not defined is 15.
  • Switched C++ language level used to C++14 on all platforms.
  • Web compatibility and scripting improvements:
  • Implemented geometry .from* static constructors for web compatibility.
  • Implemented partial support for CSS calc() in color keywords.
  • Implemented Array "find from last" feature (findLast and findLastIndex).
  • Implemented Object.hasOwn(object,property).
  • Implemented several additional Intl API methods and functions. This improves web compatibility with sites making use of things like hourCycle, advanced DateTimeFormat, Intl.Locale, and Intl as a constructor.
  • Cleaned up some unused code.
  • Removed support for Mozilla "experiment" type extensions.
  • Improved the JavaScript garbage collector's sweeping. This should fix a few intermittent crashes and improve performance.
  • Implemented some structural changes to the source to make future porting easier, and preparing for switching to C++17.
  • Removed handling of symlinks for directory linstings to prevent potential security issues by walking symlinks when uploading. This effectively reverts a change made in Firefox 50 where this functionality was introduced. A case of "Not such a good idea after all" ;-)
  • Updated the list of extensions on Windows treated as "executable".
  • Security issues addressed: CVE-2023-37208.
  • Made preparations for for requiring Authorization in CORS ACAH preflight.
  • Since no browser honors this part of the spec at the moment this is left disabled until there is consensus among browsers.
  • UXP Mozilla security patch summary: 2 fixed, 2 rejected, 20 not applicable.
