A small icon will prompt up after you selected some text. The selected text will auto copy to clipboard when you move the cursor over the icon.

You'll need a userscript client that supports GM_setClipboard, or it will prompt an alert. (both Greasemonkey & Scriptish support the API)

I wrote this script because Firefox's copy in contextmenu is very unreliable, it makes my life easier...
