Activities and webslice in Firefox
This is the thing we like about Firefox, the thing that makes Firefox the best browser.
If some browser comes up with a cool feature, Firefox too will have it. If we want some feature in Firefox it is bound to come by sooner or later. There are millions of developers developing add-ons to make Firefox a better place for everyone.
Within 2 days of release of Internet Explorer 8 beta 1, its two main features Activities and webslics were available for Firefox. Get the feel of new features of IE8 in Firefox. Get the add-ons here Activities & webslice.
