Best one for copy/translate! Rated 4 out of 5 stars
But for me the translate function doesn't work anymore (Google/Bing -> German).
My fault, add-on fault or what?

"Popup Delay" (variable seconds):
Mouse movement in this Delay time stops Popup but copied selected text to clipboard.
Like "Auto Copy" addon with short flashing text after selection.
