BTW: Using the system principal for my sandbox lets me use the privileged XHR implementation in FF19+. However, this seems to break the code in FF<=18 (where I used a chrome window as the principal for the sandbox). I'd like to preserve backwards compatibility at least for a version or two. For now I'll use nsIXULAppInfo to check the version, but if there's a way to check the capability directly I'd prefer that. Can anyone point me to the bug where this behavior was changed? _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
