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 the popular Firefox browser.
Having seen the advantages of 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 losing 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 Mozilla Firefox’s default layout if they so wish.
- Changed the way dates and times are formatted in the UI to properly adhere to the user’s regional settings in the O.S.
- Re-enabled the DOM Filesystem API for web compatibility.
- Moved the global user-agent override to the networking component. See implementation notes.
- Worked around crashes and run-time issues with module scripts. See implementation notes.
- Fixed a website layout issue with table-style elements potentially overlapping when placed inside a flexbox.
- Fixed some code logic issues with WebSockets.
- Fixed a regression when waking the computer from standby causing high CPU usage in some uncommon situations.
- Updated the list of prohibited ports the browser can use. See implementation notes.
- Updated root certificates.
- Windows: Changed the way downloaded files without an extension are handled. See implementation notes.
- Mac-beta: Improved version detection of macOS including Big Sur.
- Security issues addressed: CVE-2020-26978 and CVE-2020-35112.
- Unified XUL Platform Mozilla Security Patch Summary: 2 fixed, 1 deferred to the next release, 16 not applicable.
- The global user-agent override was moved to the networking component where it is actually implemented. The new preference name is a network.HTTP.useragent.global_override. Please note that using a blanket override is normally (very) counterproductive and does not, in fact, help much with privacy. It would also override the compatibility modes (Native/Gecko/Firefox) in Pale Moon. As such, the browser will now warn you if the user-agent is globally overridden (in preferences) and allow you to easily reset that override and re-enable the various compatibility modes.
- Prohibited ports: Pale Moon maintains a blacklist of ports the browser may normally not connect to on servers, to mitigate abusive web scripting employing your browser as an attack bot on servers (e.g. by connecting to mail servers or whatnot), NAT slipstreaming, and similar security issues. To more thoroughly prevent known abusable ports on servers, this list was extended with a number of additional default ports for various non-HTTP protocols.
- Downloaded files without a file extension: When a file without an extension is downloaded, we will now open the download folder where you may choose to take any specific action manually, instead of trying to execute it as a program or through an associated program.
