iMacros is a browser based application for macro recording, editing and playback for web automation and testing. It is provided as a standalone application and extensions for the Mozilla Firefox, Google Chrome, and Internet Explorer web browsers. Developed by iOpus/Ipswitch, It adds record and replay functionality similar to that found in web testing and form filler software. The macros can be combined and controlled via JavaScript. Demo macros and JavaScript code examples are included with the software. Running strictly JavaScript based macros were removed in later versions of iMacros browser extensions. However, users can use alternative browser like Pale Moon, based on older version of Mozilla Firefox to use JavaScript files for web based automated testing with Moon Tester Tool.
