Internet Explorer 7 vs. Firefox 2.0 » A Complete Waste of Time

a quote here .... "I found it interesting to learn of one of the first cross-browser extension, called Trailfire. Trailfire is a Firefox Extension; Internet Explorer 7 add-on, and essentially a hosted service that allows users to comment on the websites they visit, leaving a 'trail' so to speak.... I believe we'll be seeing many more cross-browser extensions in the near future."
