While I was reading old posts (I have hundrends of posts left to read), I came across this post regarding Copernic Desktop Search caught my atention.
Copernic Desktop Search 1.5 Beta was released on February the 23.
Unlike other similar tools (google, yahoo, askjeeves…) Copernic suports Mozilla Thunderbird. This is the reason why I decided to give it a try. None of the others support Thunderbird, and don’t even support Firefox.
