Page Update Checker (aka PUC pronounced as Puke) is a FireFox extension that automatically checks to see if Web pages have changed. Once installed, you will be able to right-click on any page in Firefox and select 'Monitor for Updates'. The PUC options will open up and you can select how often you would like PUC to download the Web page and see if it has changed. To return to the options menu later, select Tools-Page Update Checker Options. This version is the first release on CNET Download.com.
