Web Dev/Design Firefox Extensions


Use the eyedropper to pick the colour you’d like to steal from a website. Alternatively, get it to analyse and display all the colours used on a website and steal them that way.


View and edit HTML, CSS and JavaScript in Firefox. Great for seeing results of any little changes instantly.


We all know chaps like to measure things, no matter how small. Now you can measure your website.

Screen grab!

Great extension for taking a full screenshot of a website – top to bottom no matter how big. You can also take screenshots of any selections you wish to make.


Create your own style sheets for websites and customise the way they look. Great for getting rid of adverts or making all the text your favourite colour – pink!
