Changes in Pale Moon 19.0 (2013-02-20):
* Update of the underlying Firefox (gecko) code to v19. This has a number of consequences:
o Add-ons and themes may need to be updated since the UI code has changed.
o HTML5-implementation is more complete
o A number of CSS statements have their prefix removed (-moz*)
o Javascript now uses the IonMonkey engine by default, which is a new (faster) engine
o Improvements to the layout and rendering engines
o 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.
