@remi But about three months ago you could click the 'add' button and it would populate the list with the tabs you had open or had recently closed, which was much more convenient. Now you have to open a tab, copy and select the address, then open the speed dial, click add and then paste the address. Not too bad for one site, but much less convenient for adding multiple sites in a row, and definitely a step backwards.
Now it show suggested sites, which is universally useless but I assume earns them something.
It is still possible to right-click a page and add it directly but you need to find an element which doesn't hijack the right-click.
