Versie 19.0 van Pale Moon is uitgekomen, als opvolger van 15.4. Deze webbrowser maakt gebruik van de broncode van Mozilla Firefox, maar is geoptimaliseerd voor moderne hardware. De Windows-versie van Mozilla Firefox wordt namelijk ontwikkeld met een zo groot mogelijke compatibiliteit in gedachten. Mede door concessies aan oudere hardware is de browser niet zo snel als hij zou kunnen zijn, aldus Pale Moon-maker Moonchild Productions.
Pale Moon is functioneel nagenoeg gelijk aan Mozilla Firefox, maar biedt geen ondersteuning voor oudere processors. Ook zijn enkele zaken weggelaten, waaronder 'Accessibility features' en 'Parental controls'. Daarnaast is er een 64bit-versie van de browser beschikbaar. Het resultaat is een browser die soms tot 25 procent beter zou presteren. Meer informatie over het programma kan hier worden gevonden.
De download van Pale Moon is alleen in het Engels, maar met behulp van dit taalbestand en een kleine aanpassing is het programma ook in het Nederlands te gebruiken. Het programma gebruikt zijn eigen profielmap en deelt deze niet met Firefox, waardoor het mogelijk is om de twee naast elkaar te gebruiken. Deze uitgave is gebaseerd op versie 19 van Firefox en hieronder is te vinden wat er allemaal is veranderd en wat de verschillen zijn ten opzichte van Firefox 19.
Pale Moon 19.0 released!
Main points where this release differs from Firefox 19:
- 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.
- I'm aware that this may be inconvenient for users with a lot of add-ons installed, but the core engine changes are of too great importance not to push forward. Add-ons compatible with the v15 code base may not work properly or at all on the new release because of the far-reaching changes to the rendering engine, CSS and HTML5 implementations and evolving standards. It is strongly recommended not to force compatibility (changing files in xpi or telling pale Moon not to check extension compatibility) but instead to find updates for your add-ons, or, if no "Firefox 19" compatible versions are available, look for alternatives with the same functionality.
- HTML5-implementation is more complete.
- More elements of the still-evolving HTML5 standard have been implemented, giving the browser more functionality and features for web developers to use.
- A number of CSS statements have their prefix removed (-moz*).
- CSS statements that were considered provisional or experimental have been finalized, and the syntax with the provisional prefix "-moz-" has been replaced with the finalized CSS syntax. For example, "-moz-transition:" should no longer be used, but instead "transition:".
- Improvements to the layout and rendering engines
- The most important improvements in the gecko v19 core are improvements to the layout and rendering engine. This is all under-the-hood, to improve page display speed and the use of your GPU if possible.
- If you are using a language pack, you need to update it to the latest version!
- Pale Moon normally refuses to run an older language pack but if you have disabled version checking in the browser, you will end up with a non-working language pack when updating that will prevent the browser from starting. If this happened, you can start Pale Moon in safe mode and download the proper language pack for v19.0
- Update of the browser style. Main browser controls and the padlock look slightly different.
- This style change was mainly prompted by a strange glitch in the back/forward button, making it not work as it should with the Pale Moon theme and layout. The navigation controls have been slightly re-styled, specifically for disabled controls. To streamline the overall theme, the older "striped" padlock has been replaced with a look similar to the rest of the controls; Also a change in color from yellow to blue for regular HTTPS to stay in line with the rest of the identity panel.
- 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.
- This includes, among other things, improvements to scaled images (e.g. IE Chalkboard test) and certain types of gradients that are off-loaded to the GPU for rendering. Specific attention has been paid to mitigate a number of regressions present in current releases of Firefox, that would in fact cause the browser to stall or become completely unresponsive; most of these issues and solutions to them are Windows-specific.
- The builds no longer use PGO (Profile Guided Optimization) but are globally speed-optimized.
- PGO has shown to be less effective in VS2012 on the Mozilla code, and the workarounds/tradeoffs to circumvent compiler issues can, as a result, be removed, resulting in code that is optimized better overall. This decision is in line with the move away from synthetic benchmarks and towards overall browser smoothness and performance in daily use.
- The in-browser PDF viewer is not enabled
- Pale Moon's approach has always been that the browser should remain a browser, not spread thin over multiple disciplines or opening up security issues by integrating and enabling potentially exploitable code. The PDF viewer code for in-line viewing of PDF documents is present but disabled by default. It is provided as an emergency measure only (just like in v15) and you are at all times strongly urged to use a standalone, external viewer for PDF files.
- The PDF viewer has been available in Firefox Aurora and Beta builds for a number of months, and Mozilla has finally pushed it through to the release channel, but this is despite the fact Mozilla has acknowledged the existence of “several UX/rendering/stability concerns”.
- Several user interface items are present that were removed from Firefox
- In Firefox, switching Tabs to the bottom once they have been placed on top has to be done through about:config - Pale Moon retains the context menu option in both directions
- In Firefox, there no longer is a "Send Page" or "Send Link" context menu item to quickly open a new e-mail message in the configured mail application with a link to the current page or pointed link. Pale Moon retains this feature.
- In Firefox, the "Safe mode" startup dialog has one recovery function next to safe mode: reset the entire profile. Pale Moon retains several choices for troubleshooting and resetting parts of the profile, and completely resetting your profile is done from about:support instead.
