Installed both and it does certianly seem quicker.

fasterfirefox installed no problem with microb rstarting after 10 seconds, but when installing speeddns, having pressed 'restart' it just seemed to wait there. After 30 seconds or so, I closed down all instances of Microb, started it up and speeddns was there on the addons page.

Nice 'easy' way of speeding up browsing
