Update Scanner is a Firefox plugin which will automatically scan and inform users about changes and update of a website. Users can add any websites to the monitor lists.
There are some websites which don’t provide RSS subscription, or you want to get update about the comment on article, but the author didn’t install “Subscribe To Comment” plugin. So, how are you going to get informed when there are changes on those website? View them everyday? Sure this is not a smart way.
Update Scanner can help users on this, by add a option to Firefox context menu. When you want to monitor changes on certain website, simply right click and choose “Scan page for updates” and you can set the scan frequency and threshold, so that you won’t get update too often.

If you would like to manually scan all websites in your list, you can go to Tools -> Update Scanner. A sidebar will appear and show you the list of websites that you monitor.
Tips: I would suggest that you set the Autoscan to a larger value, so that you can save your bandwidth for other usage.

Seems like this Update Scanner will browse those sites in the background to check for any updates? -_-
Probably useful for those who need it, not me though.
Seldom got blogs that don’t provide RSS subscription. So I just skip this.
Anyway, nice finding!
“Seldom got blogs that don’t provide RSS subscription.”
That’s true, but many of them do not install subscribe to comments plugin. So this tool is still pretty useful when we want to follow up comments of a blog.
I use this all of the time. Great tool. I am trying to find out where the file is saved on my hard drive so I can transfer to another computer.
