A while back there was mention of Google not pushing Firefox like it used to.

This may be why.

Duck Duck Go Toolbar 1.1.4

Blocks 42 Million useless Web sites (with nothing but ads) and lets you more easily use our search engine (duckduckgo.com), which omits blocked domains from search results. If you’re like most people, you’ve been to many of these useless Web sites from either other search engines or by slightly mistyping Web addresses, e.g. yotube.com, facebok.com, turbotx.com, twitterr.com, etc. Fight typosquatting!

Is this popular? Well, there has been over 1,500 downloads just in a couple of days.

The add-on appears to block typo sites.

Not one to jump to conclusions, but when reading the long explaination, I came across this statement -

We partnered with the Parked Domains Project to develop this toolbar, which is a project that identifies parked/spam domains. These blocked domains have also been removed from our search results. For the full list of sites blocked, check out their Web site at http://www.ivegotafang.com/

According to IveGotAFang website:

What is a parked domain?

A parked domain is an Internet site without anything real behind it. Often parked domains are just generic Web sites that just have advertisements on them, e.g. arthritis-expert.com

How can I report parked domains?

Thanks—we need all the help we can get! You can report them on our site here. Or can you drag the following link (bookmarklet) to your link bar and report them whenever you see them “in the wild:” Parked Domain.

The last person to leave, please turn off the lights.
