[tor-commits] [tor-browser/tor-browser-24.1.1esr-1] fixup! Add mozIThirdPartyUtil.getFirstPartyURI API

[mikeperry@xxxxxxxxxxxxxx]

commit 2df3a6e502c52c4a8e3bc34921aad0eda80af340
Author: Kathy Brade <brade@xxxxxxxxxxxxxxxxx>

    fixup! Add mozIThirdPartyUtil.getFirstPartyURI API
    
    Add mozIThirdPartyUtil.getFirstPartyURIFromChannel() API.
    
    Marked getFirstPartyURI() as [noscript] since it cannot be
    called from JS due to its use of an nsIDocument parameter.
    See Tor bug # 8167.
