Comment (by boklm):

 Those patches are fixing the build, however it seems it is not enough to
 get the sandbox working on Windows 64. After starting the browser the
 `about:page` tab stays blank. When trying to load a web page in a new tab,
 the tab also stays blank. After changing `security.sandbox.content.level`
 from `1` to `0` in `about:config` and restarting, the browser is working
 correctly.

 To try to debug this I tried setting `security.sandbox.windows.log` and
 `security.sandbox.logging.enabled` to `true`, but didn't see anything
 related to sandbox in the browser console.
