Source: Greasemonkey UserScripts Updater
Greasemonkey userscripts can be very helpful in many situations that are regularly encountered on the web. They manipulate elements on a website to either remove, add or change them without the user noticing in the background. There are basic scripts that have been designed for one specific purpose like removing all ads on a website or adding download links to photos but also more advanced scripts that combine many new elements into one script. What all have in common is that there is no way of getting informed about script updates. At least not by normal means. Script updates are important as userscripts have to be modified if websites change elements on their pages. Results can be non working or broken userscripts.
