CoLT...hits the target Rated 5 out of 5 stars

Simply put, and quoting from the CoLT add-on page, this little extension adds two menu items to the context menu when a link is right clicked. These menu items copy both the hyperlink's text and URL to the clipboard in the format you choose: either as plain text, as an HTML hyperlink, or as a custom format (which you may specify)
It's a small extension (21 KB) that performs one simple function very well.

This review is for a previous version of the add-on (2.2.1).
