Setting up the plug-in will take you no more than 30 seconds.
Open a page with the free version of Wordtracker.
See the text below left: “If you are using IE 7 or Firefox 2 ...”? Click on the link “Wordtracker keywords”.
A dialog box will appear.
Click "Add” and the window will disappear.
Now look in the upper right corner of the browser.
Click the arrow on the search bar and select Wordtracker.
Now you can type your word or phrase in the search panel
and get the result right away.
I hope you find this advice useful.
