I just wish they'd focus more on producing a great browser and less on random, wacky, side projects. Not that the side projects aren't interesting, but the browser is what I care about. Even this person, who is associated with Mozilla can't say anything more positive than "[w]e have a good browser...".
That said, he's right... `sudo apt-get install firefox`.
There are halo benefits to the side projects as well. Some experimental or otherwise "daring" functionality in a side project can become invaluable within the browser core at a future date. It's a bit like an external stimulus triggering a random mutation that proves to be beneficial.
Ex: Popup blocking required modification to the browser before it became a vital core feature.
