Page Reboot - add a link to the page and that page will re-load at the interval you specify. Good for breaking news stories, sports results......basically anything that gets updated fast.

Secure Password Generator - my new favourite Firefox extension. At the click of a button, generate long password strings and copy them to the clipboard.

CoScripter - another Firefox extension for recording, automating, and sharing processes performed in a web browser such as printing photos online, requesting a vacation hold for postal mail, or checking bank account information.

HideLinks - Shorten links and password-protect your browser favourites.

Web2PDF - provide "save as PDF" capability for your blog or website.

AddThisPost - now you can allow visitors to your blog or article directory the ability to quickly add posts and articles they like to the bookmark sites they use. No extensive coding. No having to hunt down icons. Just include one simple line of code.
