Portable Fonts Mode in Firefox

After reading the Bug 998844, I knew that Mozilla Firefox had supported a portable font mode since 32.0, but it was only enabled on Android, so now I use –enable-bundled-fonts to enable this feature for desktop firefox, here is the prebuilt test edition’s TEST LINK, of course, I haven’t applied most optimization for the test edition.

You can put some fonts to firefox/fonts directory to check whether the feature is effective.

And another thing, I try to add Google GEO API Key and Google Oauth API Key to this edition, and the custom build editions have lacked these keys for a long time, which cause some functions not to work. You can try the GEO link1 and GEO link2 to test Google GEO API. And you also can try to use Firefox Hello service import Contacts to test Google Oauth API.

Additionally, Mozilla has provided a new about:config option dom.ipc.plugins.flash.disable-protected-mode to configure Flash protected mode off since 35.0, and you can set it to true to test it. You can read the details from Bug 1108035 and Bug 1112709, I also use the Bug 1112709 patch.

I plan to add these features to my 35.x release edition, and after my 35.0 is finished, I will check it in order to make it pass virus total test, so that will cost me some time and may decrease some performance.

Rendering problems after Fx32

Someone encountered some rendering problems after fx32 is released, and some issues are caused by OMTC, and some issues are related with GPU. Mozilla continuously fixed the related bugs until present.

After Fx34 is released, I noticed someone on Win7+ also has the strange issue, their part of about:support is

AzureCanvasBackend          skia
AzureContentBackend         cairo
AzureFallbackCanvasBackend  cairo

And I think the normal value is

AzureCanvasBackend          direct2d
AzureContentBackend         direct2d
AzureFallbackCanvasBackend  cairo

I asked someone for their GPU hardware, which is Intel HD Graphics 4400 / AMD Radeon HD 8670M Driver Dual GPU.

I searched the type in Mozilla Bugzilla, it seemed Fx33 changes limited the Dual GPU type, which will disable some features and they caused some issues, you can see in Bug 1097321. It is fixed in Fx37, and I try to ask someone who has the issue use the edition, which solved their problems.

Maybe the custom builders should consider the Bug 1097321 patch next edition.
