Copy text in Windows just like in Linux

I had been searching for a software that would bring the copy style of Linux to windows - which is - any selected text gets copied to clipboard automatically without having to click another time to copy.Similarly, paste is just a click on middle button.

While I haven't found a software that has this functionality throughout windows, there is a software - a firefox add-on actually called 'Auto Copy'- that does it.

Another add-on that goes along with it is 'Copy Plain Text', that removes the formatting data that also gets copied usually when you copy something - the things like Font design,colour,font size & other annoyances. So no more using notepad to get the plain text!
