When visiting sites (including Firefox's help page!) I am seeing double underlined links in green type randomly throughout website pages that link to a Groupon subscriber site. Is my machine compromised, or is it just Firefox 5.0?

You can block both intelliTXT and Google Ad-Sense with a hosts file and with Adblock Plus.

Having a good hosts file on your system can protect your entire system cross-application and all browsers and all your Firefox profiles against a lot malware. The hosts file must coded for www.example.com, example.com, anything.example.com -- Adblock Plus is more generic and can do more with less coding -- subscribe to the EasyList US filters as ADP will do nothing without filters. See links below.
