Google is undisputedly the best search engine out there on the Internet, however there are a few ways by which you can customize Google and make it even better.

I have got 3 best free Firefox extensions using which you can customize Google by adding extra useful information to your search results and remove unwanted information like ads, spam and click tracking so as to improve the overall searching experience. The following are the 3 best extensions for Firefox using which you can improve the search results.

1. OptimizeGoogle:

Using OptimizeGoogle, you can get rid of text ads from Google search results, add links from about 10 other search engines, add position counter, product results and more. You can even filter your search results to see dead websites (using WayBack Machine) and remove click tracking so that you can search anonymously. Here is a list of some of the other useful features of this plugin:

1. Use Google suggest (get word suggestion while typing)
2. Add more security by using https wherever necessary
3. Filter spammy websites from search results page
4. Option to remove SideWiki
5. Add links to bookmark your favorite result
6. Add links to other news and product search sites

To install the plugin, just visit the OptimizeGoogle page from your Firefox browser and click on the Download button. Once installed, you can enable or disable the customization options from the Tools -> OptimizeGoogle Options.

After you customize Google to improve the search results, how about adding a feature that provides a way to preview the website in the search results itself? Here is a miracle Firefox extension to this job for us.

2. SearchPreview:

SearchPreview (formerly GooglePreview) will insert thumbnail view of the web page into the Google search results page itself so that you can take the guess work out of clicking a link. Just install the plugin, reload Firefox and you will have the SearchPreview at work. You can install this plugin from the following link:

OptimizeGoogle and SearchPreview have made our search results smarter and faster. Now how about safer? Well you have another Firefox plugin to make your search results safer as well. Here we go.

3. McAfee SiteAdvisor:

This is a free browser plugin that gives safety advice about websites on the search results page before you actually click on the links. After you install the SiteAdvisor plugin, you will see a small rating icon next to each search result, which will alert you about suspicious/risky websites and help you find safer alternatives. These ratings are derived based on various tests conducted by McAfee.

Based on the quality of links, SiteAdvisor may display Green, Yellow, Red or Grey icon next to the search results. Green means that the link is completely safe, Yellow means that there is a minor risk, Red means a major risk and Grey means that the site is not yet rated. These results will guide you to Web safety.

SiteAdvisor works on both Internet Explorer and Firefox which you can download from the following link:

Here is a snapshot of all the 3 plugins at work:

I hope you enjoy these 3 plugins which make your searching experience a lot more simpler and safer.
