We need a simple Firefox extension (or addon, or whichever the proper terminology) that appears when you "right click" on the page in the standard dropdown. So there is like "save page", "save image", etc....and now our words will show up there as well.
When someone selects this options (our new option they see after installing the extension)....They are redircted to our web site with the time embedded as a string variable.
Also, there is a small configuration section I assume at the Top inside Firefox.
That's it really.
