Greasemonkey is a extension of Firefox which allows users to do client level tweaking/changes in the web pages. Greasemonkey can be used  for following purposes:

  • To add new functionality into the web page.
  • To remove unwanted feature from the web page
  • To simplify your work with doing bulk jobs in single shot.

According to the Greasemonkey book (link given below) “Greasemonkey is a Firefox extension that allows you to write scripts that alter the web pages you visit. You can use it to make a web site more readable or more usable. You can fix rendering bugs that the site owner can’t be bothered to fix themselves. You can alter pages so they work better with assistive technologies that speak a web page out loud or convert it to Braille. You can even automatically retrieve data from other sites to make two sites more interconnected.”

Greasemonkey programming is not tough to learn as it is most of java scripting. But a little bit different. Dive into Greasemonkey is a book written to help programmers to write scripts for Greasemonkey. Though the book is pretty much outdated and it is clearly written on the Website that there are very rare chances of getting it updated, but still it is the best resource available online if you would like to get your hands on writing Greasemonkey scripts. Also you can get lot of help from the Greasemonkey Wiki (link is given in the References manual), which gets updates from time to time.
