Just found a time saving extention for firefox which lets you copy anything to clipboard automatically when you select the text. This is real time saver if you can remember the features of "good old days MiRC" and Trillian. This one does copies to clipboard as soon as I select text or other elements of the web page. The other handy shortcut is "Paste on middle click" which makes Cntl-V unnecessary. It's a huge timesaver, just try it and you'll know.
AutoCopy's a free download, works wherever Firefox does.
