Pale Moon (64-bit)

What's new in this version:

Most notable user-facing/implementation changes:
- Implemented Global Privacy Control, taking the place of the unenforceable "DNT" (Do Not Track) signal. If you previously enabled DNT, then this preference will be adopted for Global Privacy Control (GPC). Through GPC, you indicate to websites that you do not want them to share or sell your data.
- "Default browser" controls in preferences has been moved to "General"
- Updated emoji support to Twemoji 13.1
- Implemented Selection.setBaseAndExtent() for web compatibility
- Implemented queueMicroTask() for web compatibility

For add-on developers:
- Pale Moon now internally identifies with the Firefox GUID. This does not affect how it identifies to the web.
- Direct support for legacy Firefox extensions has been restored. Pale Moon-exclusive extensions will need to be updated to target the Firefox GUID in their install manifest and, where applicable, in their JavaScript components and overlays.
- The browser no longer lives in a "browser" distribution subdirectory. If you are hard-coding paths this may affect you.
- appinfo.platformVersion is frozen for backwards compatibility. If you need to detect the platform version, you should use appinfo.greVersion instead.
- Themes: scrollbar-width is now mapped to an attribute on scrollbar controls (bars, resizers and corner controls) for better theme support of thin scrollbars.
- Language packs: the entire internationalization structure has changed; because this required re-verification of translations, some language packs may have a few more untranslated strings in them at the moment until our volunteers over at Crowdin catch up on the new milestone.
