Chrome: Automator is one of the easiest ways to automate tasks on your Mac, and the ability to record mouse actions makes it so just about anyone can create their own workflows within seconds. Wildfire is a Chrome extension that attempts to bring a similar feature to Chrome.
Wildfire essentially allows you to create little macros based wholly in Chrome. Tap the record button, and Wildfire records everything you do, eventually turning that into a workflow. These actions can include mouse clicks, changing tabs, creating tabs, scrolling a page and inputting data. How useful this is depends entirely on how much time you spend in your browser and what you do with that time. Regardless, it's a neat tool that might prove useful for anyone who does a lot of repetitive tasks.
