iMacros was designed to automate the most repetitious tasks on the web. With iMacros, you can quickly fill out web forms, remember passwords, create a webmail notifier, download information from other sites, scrape the Web (get data from multiple sites), and more. You can keep the macros on your computer for your own use, or share them with others by embedding them on your homepage, blog, company Intranet or any social bookmarking service.
Web professionals can use iMacros for functional, performance, and regression testing of web applications. The built-in STOPWATCH command captures precise web page response times. iMacros also includes support for many AJAX elements.
iMacros can be combined with other extensions such as Greasemonkey, Web Developer, Firebug, Stylish, Download Statusbar, NoScript, PDF Download, Foxmarks, Fasterfox, All-in-One Sidebar, Megaupload, Foxyproxy, Flashblock and Adblock.
