Pale Moon 33.4.1

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 33.4.1 (2024-11-05):

• Added a processor check to the 64-bit installer for Windows to check for AVX.
  Note: this check does not work on Window 7/8/8.1 and will allow installations on non-AVX processors there.
  Note: if you are running Windows 10 before build 2004 (before 20H1), this check may fail on AVX-capable CPUs and prevent installation.
• Improved handling of multipart/mixed documents. (CVE-2024-10461 and CVE-2016-2816) DiD
• Addressed CVE-2024-10463.

Changes in Pale Moon 33.4.0.1 (2024-10-09):

• Extension compatibility issues with the ghostbuster (leading to tab handling problems).
• Windows 7 compatibility issues in 32-bit builds on some systems (leading to application UI paint failures/black window).

Changes in Pale Moon 33.4.0 (2024-10-08):

• Introduced the “ghostbuster” concept; this is an automated internal mechanism to attempt cleanup of particularly problematic web content after a tab or window is closed. See implementation notes.
• Added support for the PROT_MPROTECT security feature on targets that use it (notably PaX and NetBSD).
• Implemented preferences to give the user control over the Same-Origin Policy (SOP) and CORS preflight. See implementation notes.
• Improved buildability on NetBSD and Altivec architectures.
• Fixed building issues on Apple Silicon Mac with XCode 16.
• Added workarounds for non-standard MSE/WebM/VPx encoding on YouTube that could cause video buffering and halting issues.
• Dev: Changed the default credentials mode for module scripts from ‘omit’ to ‘same-origin’, aligning with mainstream.
• Dev: Implemented getTransform and setTransform with DOMMatrix arguments.
• Dev: Implemented ES2023 Hashbang grammar proposal.
• Fixed an issue with JavaScript’s StructuredClone.
• Security issues addressed: CVE-2024-9396.
• Rejected: CVE-2024-9398 (properly informing the user about attempts to use unhandled protocols by web pages is considered more important than potential determination whether a handler for such a protocol is installed)

Changes in Pale Moon 33.3.1 (2024-09-10):

Changes/fixes:

• Backed out support for FFmpeg 7.0/libavcodec 61 (Linux) due to it causing a major regression in WebAudio (broken on all platforms). This is being worked on to re-land at a later date.
• Restricted the NotifyPaintEvent interface to chrome code only; there is no reason (other than potential tracking/fingerprinting) to have this accessible from content.
• Fixed a potentially exploitable issue in JavaScript (FetchName).
• Fixed a code correctness issue in XPConnect when creating sandboxes. DiD
• Added a warning for using externally handled usenet protocols.
• Security issues addressed: CVE-2024-8383 and CVE-2024-8381.
