I used to love Gator — it made filling in online forms a breeze, and kept my credit card information handy so I didn’t have to pull it out every time I bought something online. But Gator apparently wasn’t satisfied with providing that great service, and started with a pop-up ad program; at select websites Gator would pop up an ad of a competitor. Annoying as all heck. Six Continents Hotels is obviously annoyed too — this week the company filed suit against Gator.
