Sync default preferences for OSX plugins from Firefox
Bug 759364 - Run the Silverlight plugin OOP in 32-bit mode on OS X. Bug 788399 - Always use async drawing for OOP windowless plugins.
> +pref("dom.ipc.plugins.enabled.i386.silverlight.plugin", true); Bug 759364 - Run the Silverlight plugin OOP in 32-bit mode on OS X. > When building on OS X 10.7 and up, the linker by default prevents code execution > on the heap. But the Silverlight plugin does execute code on the heap, and > crashes on startup when heap execution is forbidden. > > In the patch for bug 753248 we've stopped the 10.7-and-up linker from preventing > heap execution in the plugin-container process, but not in the main process. We > don't want to lose the protection against heap execution in the main process > (where most of our code runs), but think it's a reasonable compromise to allow > it in the plugin-container process. (Chrome behaves similarly -- see bug 753248 > comment #50.) > > This means that Silverlight doesn't crash in 64-bit mode (where it runs out of > process). But currently Silverlight defaults to running in-process in 32-bit > mode on the Mac, so it always crashes (and brings down the browser) in 32-bit > mode. > > Though we don't really support running in 32-bit mode, we gain flexibility by > making Silverlight run out-of-process in 32-bit mode. > -#ifdef XP_MACOSX > -pref("plugins.use_layers", true); > -#endif Bug 788399 - Always use async drawing for OOP windowless plugins.
