Addendum: I tried disabling NoScript and Adblock, since this was the advice given for a similar problem with several other sites. The result was I now have to wait for the ad to load, but it still doesn't skip the 5-sec wait time, let alone skip the ad page completely. So, not only did this advice not help, it made things worse. With the economy sluggish, more & more individuals and small companies are using adf.ly, so it would be nice if this could be fixed. I'm using Firefox 19, but suspect all versions of Firefox have a similar problem with these types of sites.
