coComment [ cocomment.com ]
UPDATE: Dewayne Mikkelson pointed me to this [ SolutionWatch ]. The extra manual click for activating coComment can be automated through a script. Just install GreaseMonkey [ mozdev.org ] (a FF extension to execute user scripts on web pages), and right-click on the link to the script, selecting “Install User Script…”. Done !
