Is there anyway to get a dropdown list of addresses typed on the address bar like Opera 12 ?

Still a die hard user of 12.17 here, the only feature left for me to switch would be a drop down address bar.

Since I have a arm injury I dont like using shortcuts so will remain on 12.17 or switch to another browser.. im liking portable firefox at the moment.

Is there an option or config to have the drop down address bar of your past URLs
you have entered like in Opera 12.17 ?

Its good to change GET variables when your tinkering with scripts.
