The optimized version of Firefox
Pale Moon is a custom-built and optimized Firefox-based browser for Windows operating systems with current, high performance processors. It looks identical to the standard Firefox browser and supports Firefox extensions, themes and identities.
- Highly optimized for modern processors
- 100% Firefox sourced: As safe as the browser that has seen years of development.
- Uses slightly less memory because of disabled redundant and optional code
- Significant speed increases for page drawing and script processing
- Stability: experience fewer browser crashes.
- Support for SVG and Canvas, and downloadable fonts including WOFF
- Support for HTML5 and WebGL (v4+)
- Support for Firefox extensions (add-ons), themes and personas
- Support for OOPP (Out-of-process plugin execution)
- Able to use existing Firefox bookmarks and settings with this migration tool
What's new and fixed in Pale Moon version 24.7:
- Fixed some performance issues with the new rendering engine on Windows. Rendering should be faster for all objects on hardware-accelerated layers now.
- Font rendering on Direct2D will no longer fall back to greyscale in some situations, preserving ClearType.
- CSS outlines will now properly outline the object, and not the overflow area (e.g. box shadow).
- The delay for hiding the default status has been increased from 10 to 30 seconds to keep it on screen sufficiently long but not permanently.
- Queries for "can play type" on WebM videos now get an HTML5-compliant response ("maybe" instead of "yes" as per the specification when a codec is not included in the request).
- Pale Moon's gecko rendering engine and Firefox compatibility version now properly follows the minor version of Pale Moon again instead of always returning .0 - this should help UA sniffing websites to more easily detect Pale Moon or adapt to further-developed gecko 24 versions.
- When using dark/black personas (lightweight themes), the tab close buttons would be almost invisible. They have been lightened a little to make them clearer.
- Linux: the click behavior on the address bar has been unified with that on Windows, aiming for current-day desktop-clipboard use (select-when-clicked). This is configurable with a preference.
- "In-content" preferences (preferences displayed in a tab instead of the normal dialog box) has been removed because of redundancy and incompleteness.
- Checking for updates from the about box now always puts the user in control and never downloads anything directly from the about box. It will pop up the larger update window when an update is found.
- Google SafeBrowsing, which is defunct, has been removed from the browser. privacy fix
- Made the building of the Web Developer tools optional when compiling Pale Moon through --disable-devtools.
- The Atom-optimized version no longer ships with the Web Developer tools to slim down the browser for limited platforms where these tools are considered generally unneeded.
- Fixed domain highlighting in the address bar. It should no longer randomly lose this formatting when switching tabs or otherwise updating the browser UI.
- Fixed missing click-to-play overlay on some zoom levels for plugins embedded in an iframe.
- Fixed large delays in print enumeration on Windows, especially when printing to file: ports.
- Updated the list of known domain suffixes.
- Updated site-specific user-agent strings to prevent incorrect complaints from websites (google.com, aol.com, etc.) that use poor detection scripts.
- Added granular referer control. See the release announcement on the forum for more details on how to use this.
- Added gr locale to the status bar options.
- Disabled HQ image downscaling. This is a workaround for the broken Mozilla HQ downscaling back-end causing constant invalidations and redrawing if 2 downscaled images with the same source were in view.
- Updated the NSS library to 3.16.2 RTM to address a few critical SSL issues. security fix
- There was a possibility to lose the source frame for raster images if images had to be discarded in low-memory situations. This has been fixed. security fix
- Made refcounting logic around PostTimerEvent more explicit. security fix
- Prevented an invalid pointer state in docloader. security fix
- Added proper refcounting of font faces. security fix
- Android: lots of branding updates to make it more release-ready.
- Android: explicitly set the Pale Moon Sync server in preferences.
- Android: IonMonkey (ARM): guarded against branches being out of range and bail out if so. security fix
- Android: enabled Firefox compatibility mode on Android to allow the installation of extensions from AMO.
- Android: added a "Quit" option to the app menu to properly immediately close the browser.
- Android: IonMonkey (ARM): prevented a performance issue due to clobbering the primary scratch register.
- Android: enabled mobile-specific optimizations to increase performance on mobile devices.
- Android: enabled AES-128 and AES-256 in addition to RC4 for Sync.
