TrailFire is another great Firefox extension which will let you say anything anywhere on a web page. After installing the extension you can add a trail mark to any web page with your comments or notes. A trail mark can contain text, images, videos, audios and other media types. When you give several marks the same ‘trail name’ you are forming your own navigation path on the web that is called a ‘Trail’. Then a feature that I loved is that anyone with a compatible browser can follow a trail you have created with simple next and prev buttons, in addition that you can share you trails with your friends by sending them via email, posting them on your blog or by publishing them on Trailfire.com. Another annotation service that could change the way your browse the web.
