Whenever I try to access the "about:third-party" page in Firefox - it returns with 'Hmm. That address doesn’t look right.Please check that the URL is correct and try again.'

So what should I do?

That page is only available for the Windows platform and not for Mac and Linux. You can find all valid about pages list on about:about. 

#ifdef XP_WIN
    {"third-party", "chrome://global/content/aboutThirdParty.html",
     nsIAboutModule::ALLOW_SCRIPT},
    {"windows-messages", "chrome://global/content/aboutWindowsMessages.html",
     nsIAboutModule::ALLOW_SCRIPT},
#endif
