Check md5sum too, should be 9e89b250cc9adea6203188ac63fe7cff
Fixing permissions with ROM Manager seems to do the trick, thanks.
TWRP has option to fix permissions for any native sd rom as well, but in this case it failed to do so it seems.
EDIT: spoke too soon, browsers are still FCing unfortunately.. don't know why, md5 checksum was good also.
