One big complaint about search engines is they are all rather vanilla with their visual representation.  Wouldn’t it be better if you could color code things a ‘bit more?  One Greasemonkey script that does a great job at this is Colorful Search.

Is there much you can do to improve on the modern search engines?  They all do the same thing, so it comes down to who does it best – but is that the end of it?  Maybe not.  Inserting a cloud of search terms may help make even the best search engine out there even better.  Search Cloudlet inserts smart tag clouds into Google and Yahoo interface to help you search faster.

There has been a lot of buzz around Inquisitor, the new search engine plugin for Firefox from Yahoo.  It promises to “speed up your searches like no other”.  Does it deliver? 
The idea here is to search right from the search box, rather than be taken to a new page to view your search results.  Inquisitor, over time, will learn to understand you better and tailor your results to suit your needs. 
Keyboard shortcuts, that you can add yourself [...]

Filed under the “whoops! sorry about that!” department of PR over at Yahoo (then again, they haven’t changed it yet either).  It appears when you go to Yahoo.com via Internet Explorer 7, you are given a message to upgrade to Firefox 3.  How nice of them…

Thanks Yahoo, I am sure Mozilla and the Firefox team appreciates the support!

I have been fighting my own battle with the new Yahoo! Mail beta ads for some time now. Thanks to their partnership with my DSL provider AT&T, I now have the new “ads” feature and for some darn reason I just can not warm up to it. Well thanks to a reader submission I now have a way to ditch them and go back to the clean Yahoo! Mail beta interface.
All you need to do is to pick [...]

It looks like users of the Greasemonkey extension got one more reason to jump for joy. Thanks to this handy script, you can eliminate the ability for folks to track your searching habits.

So to alleviate that at least a little bit, I have written a little Greasemonkey extension that routes the searches you would normally make on Google, Yahoo!, or MSN through a secure search proxy over at http://www.blackboxsearch.com.
Just install Greasemonkey, install the script from here (http://www.nemik.net/blackboxsearch.user.js) and visit [...]
