A little firefox zealotry.
You select text and it is automatically copied to the clipboard. No tiresome Ctrl-C, no right click, very simple and very elegant. It basically bypasses the Ctrl-C involved copying snippets of text to the clipboard. It also has another trick “Paste on middle click” which makes Ctrl-V unnecessary. If like me you are always copying huge slabs of script and stuff from the web it’s a great little timesaver.
You can get Auto Copy from the Mozilla extensions site.
