You may have seen Pocket-lint feature a handy Chrome search result blocking extension during our App of the Day series recently, and now the option has been extended to all browsers, without the need for a plug-in, courtesy of Google's new search blocking option.

The move means that you'll be able to permanently remove certain domains from your search results, with Google saying you're free to block sites "whether it’s offensive, pornographic or of generally low quality". Gives a whole new meaning to cock-blocking, eh?

You can block sites using the new "Block all" option that comes up next to the cached and similar options below the search result, upon returning to the search page.

You'll get confirmation that the site you've requested to block has been noted and you'll also have the chance to undo your blocking if you accidentally drop the B-bomb on a respectable site.

It's all linked to your Google Account, and you'll be able to manage your blocked site lists from within your account settings.

Google is saying that at the moment it isn't using the domains getting blocked within its rankings, but have said that it will "look at the data and see whether it would be useful as we continue to evaluate and improve our search results in the future".

Blocking is rolling out over the next couple of days in English for people using Chrome 9+, IE8+ and Firefox 3.5+. It will be expanded to new regions, languages and other browsers soon.
