The Speed Dial extension is a Firefox add-on that allows you to easily access your most used websites ina very easy, convenient way, just like the "speed dial" function in Opera. To show the Speed Dial tab, use the Speed Dial button (which can be added to the toolbar), or enter "chrome://speeddial/content" in your location bar.

To assign one website to Speed Dial, use the new "Set as Speed Dial" option in the bookmarks menu, or right click on the tab you want to add, and choose "Set as Speed Dial". That option is also available in the contextual area menu.

Speed Dial will be automatically loaded in blank new windows. It can also load in blank new tabs. To configure this, and other options, use the extension settings panel.
