IOpus iMacros is a free Firefox extension [1] and IE add-on [2] that may save you a lot of work. Here’s what the site says about the Firefox version: "If you love the Firefox web browser, but are tired of repetitive tasks like visiting the same sites every day, filling out forms, and remembering passwords, then iMacros for Firefox is the solution you’ve been dreaming of! iMacros was designed to automate the most repetitious tasks on the web. If there’s an activity you have to do repeatedly, just record it in iMacros. The next time you need to do it, the entire macro will run at the click of a button!"
I’m not so sure about using iMacros for passwords; RoboForm remains my top choice for that function. However, for automating web tasks like completing forms, checking stock prices, hotel rates, air fares, web forums or general website testing, this is an outstanding free tool. For support and usage tips check out the IOpus site [3]. Freeware, Windows 2000->Vista, Firefox 2 or later or Internet Explorer 6 o later, 237KB (FF), 3.43MB (IE).
