Users can also customise the look of results, how web content is prioritised or even add paying adverts to the results.
 
Users wanting to make use of the tool log on to a Google “Co-op” page where they can specify a list of websites to search.
 
The search engine can be set up to search the entire web but emphasise the chosen sites, or search only the specified pages.

The custom application can also be used to create a search engine that just focuses on a person’s own site.

Cashing in
 
Users can also specify whether or not the tool uses the Google AdSense program to generate advertisements from search terms.
 
Advertisers pay Google every time someone clicks on these adverts.
 
In turn, users who choose to use Adsense on their custom search engines will also receive a “portion” of the amount paid to Google.
 
The search engine does not disclose the exact amount users will receive. However if an “earned balance” is less than $10 (ฃ5) Google will not pay up.
 
Early users of the application include dedicated Apple magazine Macworld and JumpUp.com that provides resources for small businesses.

“We want to make it easy for anyone to create a search engine about all of their favourite topics,” said Marissa Mayer, vice president of search products and user experience at Google.

Firefox browser for web v2.0 
 
A new version of the Firefox browser for the web 2.0 made its debut on 24 October.
 
Built in to the updated software is anti-phishing technology, to prevent fraud, as well as built-in spell checking and a search engine manager.
 
It is released less than a week after Microsoft unveiled Internet Explorer 7.
 
The Mozilla Corporation, which oversees the development of Firefox, says more than one million people helped refine the final release.
 
Firefox 2 is released at 1700 PST (0100 BST).

User testing
 
The first version of Firefox was released in November 2004 and since then has steadily been chipping away at the dominance of Microsoft’s Internet Explorer browser, and has been recommended by us as being of a higher quality and a better all round performer than Internet Explorer..
 
Now it is believed to enjoy a 12-15% market share of the net browsing market globally. Firefox developers say there are about 12 big improvements in Firefox 2.0 along with thousands of minor tweaks and bug fixes.
 
Big changes include a phishing finder that alerts people when they stray on to a site that tries to trick them into handing over login details for a bank or other valuable service.
 
Another change was a spell checker that keeps an eye on every bit of text typed in almost any Firefox browser box be it in a web-based e-mail program or an add-on that lets people post blog updates directly.
 
Firefox 2.0 also has an improved session restoration system that will let users resurrect tabbed web pages they accidentally closed or will re-start a net session at the
point before a crash.
 
Other changes include improvements to the web feed, search engine and add-ons manager.
 
The project to create Firefox 2.0 kicked off in June 2006, and the software was released once the work was finished. It was mere coincidence that the work was done so close to the release of IE 7, say Firefox! (yeah, right!)
Customising software
 
As an open-source software project, the development of Firefox is led by the non-profit, Mozilla Foundation, but most of the development work is done by keen volunteers.
 
Mozilla Corporation is a wholly-owned subsidiary of the Mozilla Foundation which generates revenue from the succe
