Some of my add-ons work, some don't. But at the risk of getting set upon, I have to say, 3 doesn't seem much different from 2, to me (running and hiding, hands over ears)...
goto tools and add-ons and search for add-ons and do a search for speed dial :)
And firefox does tabbed browsing, the only difference is firefox as default doesn't have a new tab button, (which is one of the add-ons that doesn't work) but you can just do alt-tab for a new tab.
Thanks for that - but I like the look of the opera one, especially with the little + button to go to a new tab.
Also with Opera, there is two 'back' buttons - one which takes you back to the last page, one that takes you back to the original page that you entered the site on.
