Google broken links

I have been browsing Google to find Spreadfirefox.com through keyword "Spread Firefox" obviously it is the first listing appearing there, the only problem I see is that there are some broken links listed by Google there I think is very important to fix:

This is the info Google shows for "Spread Firefox":

I find a weakness here so people looking for "Spread Firefox" will see these links and will not see results.

In this case it is recommended to add some 301 codes to redirect those links to main page or resources.

This is a very common mistake that site owners have to deal with. I have found that Search Engines take off credibility and rankings when find many broken links on a site and on the user hand, this is tedious and disconcerting.

I know for this site this mistake does not represent very big problem so it is a very valuable site and it has tons of references and links, but to a small site this may be seen as a weakness.

For spread firefox community: let's keep our sites as clean of broken links as possible.

How can we fix this?
