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
This is a new major release with a lot of changes and improvements:
- Update of the underlying Firefox (gecko) code to v19. This has a number of consequences:
- Add-ons and themes may need to be updated since the UI code has changed.
- HTML5-implementation is more complete
- A number of CSS statements have their prefix removed (-moz*)
- Improvements to the layout and rendering engines
- If you are using a language pack, you need to update it to the new version
- Update of the browser style. Main browser controls and the padlock look slightly different.
- Several Pale Moon specific improvements to the rendering engine, noticeable in general use and certain benchmarks, to prevent browser stalls or high CPU usage on certain pages.
- The builds no longer use PGO (Profile Guided Optimization) but are globally speed-optimized.
