I use Firefox 4.0 (Windows) as my browser and want to do the following:
Highlight any kind of text in a browser window/tab.
Right click on the highlighted text.
In the context menu, choose from a list of all my installed search engines.
After having chosen the search engine, the search result for the highlighted text should open in a new tab.
Is there a tweak or add-in for Firefox which makes this possible?
