Powercharging FireFox using GreaseMonkey
Today I discovered GreaseMonkey mozdev.org – greasemonkey: home. Greasemonkey is a Firefox extension which lets you to add bits of DHTML (“user scripts”) to any web page to change its behavior. In much the same way that user CSS lets you take control of a web page’s style, user scripts let you easily control any aspect of a web page’s design or interaction.
Installation takes all of 3 minutes and you can then start adding (or writing) GreaseMonkey scripts, I have started with a few scripts that do the following:
- Create a Table of Contents for any WebPage – it displays a select-list at the bottom of your webpage; the list contains all header elements (h1..h#) in the page. By selecting an element in the list, the browser scrolls to that position in the webpage. This is really useful!
- Add zooming to images – a nice but not as useful script that adds a zoom menu to any image displayed in webpages I visit; with this zoom-menu I can zoom in or out on these images (usually not resulting in a very sharp images by the way)
- Check Range. It lets you check or uncheck a range of checkboxes by clicking the first checkbox and then Shift+clicking the last checkbox.
There is a long list of GreaseMonkey scripts at http://dunck.us/collab/GreaseMonkeyUserScripts. Other examples include: Exchequer: Convert prices to your own currency by hovering over them. Handles multiple currencies with the same symbol., Expand TextArea: allows you to resize textareas., Expand TextArea: allows you to resize textareas., Expand TextArea: allows you to resize textareas., PostInterceptor: Intercept POST requests and let user modify before submit.
My challenge now of course is to write my own user scripts…
