When launching firefox right after FC4t3 installation, the release notes cause a JavaScript error, from the release note doc's onload event, apparently because /usr/share/doc/HTML/offsite.js is missing.
I've removed the reference to offsite.js for now. I'm not sure if it's supposed to be there.
Judging from reading the diff on the commits mailing list, that's not enough, the error comes from: <body onload="OffSite();"> ...where the OffSite() function is probably defined in the missing offsite.js and is thus undefined. So, if removal is the way to go, the onload="..." attribute should be removed completely from the <body> tag too.
Also fixed, thanks.
