After being introduced by Opera in the 2007, most of the other web browsers started to release their own modifications of speed dial. For example: Chrome’s Homepage or Safari’s Top Sites.
Firefox labs has decided to implement a speed dial like feature by default. No, not the on similar to Google’s Chrome home pages.
Some of the features for the new tab window would be: opening a closed tab, recent pages, recent searches and zero-configuration. Another great feature would be “live bookmarks”. I just hope it is going to be integrated as default in Firefox 3.5.
